These locks are incredibly hard to get open even if you know the combination, because the ones that are actually installed in schools haven't worked properly in 20 years.
At my school, it was the other way around. As long as you got the first number right and you were within about 7 of the second and third numbers, you were good. Several times I ended up learning on lock turn in day that I’d been using incorrect numbers that were just close to the real ones.
We need to pay 50 dollars for our hallway lockers so I just use my gym locker for my stuff, we just have normal locks and I don't even use one since no one takes stuff (except for me taking locks lol)
I didn't have time to go to my hall locker, but my gym locker was a trip. I had to put the combination in exactly, but all of the numbers were slightly off. 40 was 38.5 and had to be exactly 38.5. And none of the digits were off by the same amount.
This reminds me, when I was a youngin I was sitting in the halls at highschool, wasting time, and four kids came upon a random locker, ripped the locker door out, lock, hinges and everything and chucked it out a window.
His doors are damn near pick resistant. He showed us in one video that he has a lock with a feature that lets him know if someone tried to pick it and makes the door unlockable, even with the key, if that security feature is set off.
I would not bother locking things at all if I had his knowledge. Imagine knowing your front door can be opened within 1-5 minutes - try to sleep comfortably with knowing that.
“Doesn’t require precision” clearly he’s never encountered one that’s like 20 - 30 years old and had to input the combination 6 different times the exact same way but for some reason doesn’t decide to open until the 7th
@@Averns TBH, in middle school, I just used a small hammer and chisel to break the core, and I would just open the lock with a screw driver for the rest of the year.
When I was in HS, me and my friend made a key for the back of the combination locks. It was pretty simple. We filed down old house keys until they would fit the keyway. (we were into locks and keys so we had a collection) Then filed a little more and a little more until it would open the locks with a little bit of upwards pressure. Not a perfect fit, but good enough when you knew the simple trick. I was never a thief, but I did get some pleasure in messing with the faculty. The teachers had a bank of lockers and other cabinets they used for storage. They would use old student locks and flip them around so the back faced forwards to facilitate easy access with the key. I would stealthily open them and flip them back the 'right' way. It made me smile anyway. I'm old--these were the days well before video surveillance of everything.
@@thinkiamsad Not a bump key. One that was filed close to the correct bitting. You just had to push it up slightly. We didn't have a key blank so we filed down old house keys that had similar warding until they fit the keyway, then filed some more.
lol so true, my dentist is the same, he taps around with his intruments "4 is binding, 2 is sound, 7 is clear, a negative on 3" it's hilarious i have to choke my laughter wondering what he is talking about
...unless you already know one combination (eg. know the student that used that locker before). Then it's just 50 possible offsets (0 included in case noone bothered to change it) - with the low precision, 25 tries maximum. And since 5 offsets must add up to 50, if you know the combination was only changed once... you almost always need to try a SINGLE-DIGIT number of combinations. That's mere seconds of playing with it, and you have your old locker back. Boy, truly Security with a capital S... Good thing this thing is likely to be old and worn out in reality. Anyone trying that may easily miss the right combination, keep trying and give up, just because even the right one hardly works.
At my high school, the locks were one of three possibilities: 1) The locker won't open even with a master key. 2) The locker would open if you just bopped the locker lightly. 3) You could open it in 2 seconds with a quarter. And the teachers would still complain that we wouldn't leave our phones in our lockers. XD
In mine, it was a case of seeing who used their locker. If someone used their locker, they’d definitely jammed the latch with a pencil or pen and you could just pull the handle, and if they didn’t then you didn’t have any reason to get in their locker
Ik this is late, but ima post; for us, people just put pencils in a certain part in the lock or whatever, so it wouldn't lock and would slightly be open because of just how B A D the locks were. Even if you DID get the combo right, it wouldn't open. Heck, one time someone ended up punching and denting their locker in rage because it wouldn't open.
@@niero4201 You fr? Dang, you're lucky. For me I just put the code in normally, but then you had those kids that did that pencil thing. Then you had the rare handful that brute forced it.
Phones? You guys had it easy... Corded landlines were all everyone had when I went to high-school. Yep, we had to walk uphill, both ways, everyday also..
This explains how I opened my locker every day without looking at the dial. I'd just kind of turn it in a sort of correct way but super sloppily. Apparently no precision needed
My Master Lock combination on locker at work is the same way. I can be off by 2 to 3 numbers on all 3 and it still opens. lol I never understood how that could be until today when I watched this video.
@@malthuswasrightThe ones at my high school were also ridiculously precise which is now hilarious to me considering that it was a school way out in the country side.
In my HS we're not allowed to take our book bags around to our class, Im guessing for safety, One of my friends got detention for taking his around for a not puting his backpack in his locker for 4 days in a row.
i remember my gym lockers combo to this day "ehhh somewhere around 20, next 10-15 and finally ohh your telling me it doesn't matter, Thanks gym locker" edit: after finishing the video i now know why i was able to do this
Funny how my teachers always said "it's impossible to brute force these locks" I feel like I should clarify that I mean brute force in the sense that you can’t try every combination in a reasonable amount of time.
The teacher either was told that by someone they assumed to know better than they, or, more likely, knew that it could be brute forced, but told you it couldn’t be done so that people wouldn’t try it.
The two high schools I've been to in Canada, we've never had these kinds of locks on our school lockers. You always had to bring your own lock (or buy one from the office for like 2 bucks), and then they had every student just fill out a little sheet saying which locker number was yours and what your lock combo was (everyone got to hunt around the school and just find a locker with no lock on it, and choose the one they wanted first-come-first-serve style, which was kinda fun tbh). And then, if you forgot your combo or whatever, they just had a big-ass pair of bolt cutters that the janitor was always more than happy to go retrieve lol
Ive never seen combination locks on lockers, where i live (try to guess) all the lockers have key locks built into the door I remember that when i managed to drop my locker key into the bottom of my bag, i was amazed that one of the staff carried a key on them which was able to open my locker (I generally just had my PE kit in my locker, and sometimes i put my school bag in there as well during lunchtime as we were not allowed to take our bag into the lunch hall, and sometimes i had cookery ingredients in the locker, in which case i would have to leave my bag unguarded outside, especially after the fire alarm incident that happened as a result of bags in the hallway, and there was a one way system, so to enter the dining hall you had to go out and walk around the outside of the building, and then after leaving your bag outside the door, go in through the door into a hallway, and at the end of the hallway head through the door on the left, and when heading out of the dining hall you had to go straight ahead instead going along the corridor on the right)
In America, our middle schools are like that. You brought your own padlock to school on the first day. Don’t remember having to write the combination down for teachers, though. We did get assigned lockers with these locks for the locker room, though.
Middle school and the first year of high school, we had locks a lot like these, though a little different. I forget what number the dial went up to, but the tolerances were such that you could be ±2 on each number and it would still work. Also, IIRC the third number _did_ matter, because you could turn past it and the lock would re-close. While I was in high school though, the school got added onto and remodeled, and all the lockers were replaced. Instead of installing permanent combination locks, the school issued combination padlocks -- presumably with the little keyhole in the back keyed the same (or to one of the same few keys). At the beginning of the school year, you'd pay a deposit of several dollars and get your lock. And at the end, you'd turn your lock back in and get your deposit back. Still cool to see how the combinations are changed on the installed locks. I'd suspected it involved holding the button on back and turning the dial, but didn't know the details. I knew they changed the combinations over the summer, but hadn't realized they probably rotated it between several different ones -- much easier to change hundreds of them this way!
@@AaronOfMpls If passing 3rd digit caused a reclose, if the lock was as cracked then apply slight opening force on the door so that when the bolt slid out of the way the door would open, or become very hard to turn in which case you just turn it a bit-try to open-repeat until door opens- don't need to know the last digit.
@@ferretyluv Lol you can't really speak for one of the world's largest countries and just assume it's the same everywhere. Especially with every city and county having their own school system. That's not even close to the standard here.
Still more secure than the locks my highschool used. I used to shim mine with a piece of super cheap plastic. It was actually probably faster than opening it with the combination. Would have been even faster if I used something metal.
I’ve had a few lockers before which would pop open if you gave them a good whack. Then the others could be easily raked open in seconds. But they did have only about a 1-1.5 number area around the proper combo. Do they were quite good in that respect.
The lockers at my middle school had a plastic locking mechanism, so after repeated use they wouldn't even close properly because the metal catch had carved a notch through the plastic locking lugs.
@@luxzartheglorious my best friend in middle school had one like that but you had to kick it extremely hard to make the magic happen. He eventually broke his foot after doing that every day for months.
Here is the real bypass at my high school: hold up the unlock latch, bang the locker with your closed fist or palm of hand, cheap flimsy sheet metal plus terrible tolerances on the lock lack means you can open the door faster than even a key. After I realized this I literally forgot my combination after the start of Junior year. It worked on every locker I was assigned.
I did the same thing my senior year since I didn't actually use my locker often enough to remember the code. I also coincidentally stole a lot of things from people's lockers that year.
The 5-year code rotation cycle that exactly corresponds to the number of years a student spends at the school is actually ingenious. If I was a school principal, I would be instantly sold!
I can picture some janitor at a HS somewhere watching this video, trying to figure out how to get a nerdy kid outta the locker he was stuffed and locked inside
@@BobTheHatKing you are suprised in what kind of small spaces humans can fit Esp geeky pre teens. Tooootallly unrelated. A gymbag is no fun but atleast flexible enough to allow some movement
When I was in HS, many years ago, the offset was 90 degrees, which I figured out because I couldn't picture the administration keeping accurate track of thousands of combos, so I knew there had to be a pattern. It seems I wasn't the only one to figure out the 90 degree offset so Master had to add a bit more complexity.
Interesting. Having 90 changes is criminally lazy. The offset is just notches in a disc. Having random offsets is just a matter of punching the notches in different places.
My reasoning at the time was that they just turned the dial 90 degrees wrt the guts. I.e. no offset disc. And to be fair, I have no idea who the manufacturer was.
Pretty sure you are right dave. It just allowed the front dial to slip and click into place in a second position, meaning the combination was exactly the same, but the dial face was cosmetically turned.
So, you mean the possible combinations for the lock were one-quarter of the disc, followed by same, followed by same? So with 50 numbers you'd have 13 combinations? That's pretty pathetic.
That would probably be prohibited today. An administrator needs to be able to quickly open a locker at will, without 10 minutes, 4 small diameter cutting wheels, and an angle grinder.
Alex Jamieson my school made us buy one as well, but we had to give the combination to a teacher. Which didnt mean anything since you could just swap the locks.
@@bluemaster75 Nothing. It’s simply naivety of some kind. This comment was posted two years ago and I really hate being clowned on for old comments I forgot I made.
So happy to have confirmed that the lock combinations have an offset that's the same with each iteration. I managed to figure that out from my own locker in high school (had the same one for four years with a different combo each year) but never had proof for my theory. 😄
I got out in 00, but I think we have all had that dream of running late for class in the morning having forgot to do our homework, and our locker combo not working, etc.. lol
I had to go to the office after each summer to be reminded what the number was...LOL It wasn't important enough to remember once school was out. Same lock for 4 years and I still have no clue what it was, but I know my first Phone number when I was little from the early 80's.
Step one: plan your attack on an unused locker Step two: try 5-10 different combinations throughout the day as to avoid suspicion Step three: repeat on the next day until locker opens Step four: ?????? Step five: 2 lockers lmao
Having the last position of the lock literally be functionless is inexcusable for anything purporting to be a "lock". When I was in school I was a relatively upstanding kid, but knowing what I know now, so much mischief would have happened. I still have one of my old combination locks with the master key cylinder on the back.
Even with a combo padlock, the last number is essentially meaningless (though not quite), as you can just quickly pull up and down on the shackle as you run down the numbers trying to brute force them. (If you pick the wrong third number, it's not like it resets or anything.) I had a method with early-mid-90s Master padlocks that gave me the middle digit of the combination, and brute forcing them was a snap, as you went up by two for the first digit, dialed in the second digit, and then just shook the lock/shackle up and down as you dialed down the last digit. I brute forced about a dozen of those within three or so minute (each).
I figured this out while I was in high school too, just a couple months into my freshman year I stopped even remembering the last digit and would just do the first 2 and turn till it opened
This is how the lockers at my high school were, all of the locks had a master key in the back and were all the same key, between the gym lockers and the hallway lockers. Each school year they'd take all the locks off and redistribute them, and then at registration you'd get your new combo (But you kept your locker all 4 years). My junior year someone got ahold of the master key, blocked one of the doors that never got checked, and came in on a Saturday and took all the locks off, and then put them all back on different lockers. So come Monday morning, nobody in the entire school could get into their locker, and the only way to look it up was with the code off the back of the lock.
Andrew Bowers that is a batshit insane system though. The other way around - keep the lock, change the locker - would seem to be much more useful. Or do you regularly have situations where a student and the school both think he’s gonna come back next year, and then they don’t?
I still remember my locker combination from 7th grade back in 1982. 17 - 35 - 03. I've often wondered what great things I'm not accomplishing because my brain is cluttered with such things.
I had the combinations to every single locker in the whole school. After opening a couple I got bored and did absolutely nothing with my new found super power after that.
I worked with these locks before, but the version we had had some sort of way to make it so that if you don't turn it to the final digit purposefully before twisting it further, it would just reset. There was still a pretty wide tolerance and if you just twisted it fast with decent force, it still didn't matter what the last digit was. But it did seem to be a little more secure than this one, if it was only marginal
Heh, never once had to input the combo on a locker - just lift and kick the bottom of the locker (door part). The door would vibrate enough to simply skip off the hook or slot the bolt slid into. Could open any locker, after doing enough time (bout 1/3 of a school year) the hook or slot would have eroded away enough to only require a semi forceful palm strike near the lock (technically the hook or slot on the other side) to open, no lifting required. Was very interesting to finally know what that button on the back was for though!
@@davelowets The goal would be hiring him so you can make sure it's difficult not some design flaw weakness to just pop it off so they move onto something else otherwise if they really want in it's I'm going to remove the lock with a semi.
Wow! Between middle school & high school AND the job I worked for 33 years, If I had just a penny for every time I opened one of these locks I could buy steak dinners for several people!!
I too was the go-to when someone forgot their combination. However i used my ears rather than trying out every combos. I do not know how that kind of approach is called, listenning to the klicks made as each gate frees a pin, mind shedding some light?
quick estimate because i'm bored (using numbers from my school/work routine and easy round numbers) School: 40 weeks of school per year 5 days a week (40*5=200 days) 7 years of school (200*7=1400 days) assuming 4 opens per day (4*1400=5600 openings during school) Work: 33 years of work 49 weeks per year (33*49=1617 weeks) 1617 weeks 5 days a week (1617*5=8085 days) assuming 2 opens per day (8085*2=16170) Total: 16170 work opens and 5600 school opens (16170+5600=21770) 21770 cents shuffle the decimal $217.70 assuming $15 dinner plus 8% tax (15*.08=1.20+15=16.20 per meal) $217.70 divided by cost per meal (217.70/16.20=13 meals with $7.10 left over) 13 meals with $7.10 left over
This lock brings back so many physically painful memories. I had one of these on my old gym class locker from back in the 7th grade. I nearly had to twist my arm out of socket just to open the locker. I clearly couldn’t do that now as Arthritis has set in since then.
I never had to remember my combination back in high school. All I had to do was turn the dial back a few numbers to the last combo number, and it would open right on up. It definitely made those four years of passing periods much easier.
My middle school had regular combination locks, not ones with deadbolts. I vaguely remembering hearing about a trick where you just turn the lock around on it's side and slam it hard, and BAM it opens. Public schools are never known for buying top quality for their student's security. I also remember the prank where someone could undo your lock and turn it around facing the locker so it was a pain to open.
This is one of a number of reasons I never kept anything of importance in school lockers. If I suspected someone was getting into my locker, I'd leave them a nasty surprise; like a tasty pastry, laced with ipecac.
Imagine if someone one broke in his house with a lot of evidence on how they opened a lock and he will just make a video on it and tell how the robber used a unnecessary difficult way of opening it
At my school, half of us don’t even lock our lockers, we just turn it very slightly before it locks, so it’s shut but not locked. I bet if you go along a wall and check every locker, you’d find that many of them used the “locker trick” bc we’re too lazy to open them 😅
WOW!!!! I just won one of these locks in one of SE Lock and Key's giveaways and have been experimenting (playing) quite a lot with it. I was amazed with all the features of this simple looking, everyday lock but LPL has shown me much about it that I hadn't figured out even with some instructions. Thank you for this great video.
I remember that my high school had padlock style locks with the same type of dial as these. Because they were so old, you could figure out the combination by turning them slowly and listening for where the dial 'caught'. Was quite useful when you'd just come back from break and forgotten the combination.
Has someone built a computer controlled stepper motor gizmo that will work through all of the possible combinations (reduced by the shortcuts described in this video) to make quick work of automatically opening one of these? That would be neat to see in action.
Although it's not mechanically going through combinations, thieves use laptops to run through code combinations to get around new car security and ignition interlock systems.
I was too lazy to put in my combination every time, so I rigged my locker to open from just jiggling the handle. other people I knew did the "set the first 2 digits when you leave so you just have to put in the last when you get there", so anyone could've just walked by, pulled up on the handle and spun and it would open. high school kids are dumb
@@darkmagician1184 I guess I'm old now...what would one take from a locker in the 90-95 time frame? No cellphones, no laptops (not the small ones...lol), maybe a graphics calculator and some text books. I guess kids have too much now like iPhones and laptops, and tablets.
When I was in school, half the lockers had a combo of "Kick and Yell!". I don't miss those days... I do have some vintage lockers in my garage (inherited through in-laws)... but none have locks on them (they were used with padlocks). Thank goodness!
You are a genius to figure this out. As for me, (thanks to your video's) the only number I need for this combination lock is "22" which is the caliber I would use for the Ramset !!! LOL
The first two combination numbers were my sixth and seventh grade combinations to the digit... which leads me to believe there is a lot more commonality between a set of locks at a given campus than might be desirable for security. For administrative logistics on the other hand... beautiful.
This reminds me of when I bought 300$ worth of those circular Masterlocks that have the really hard to access shackle, and put them on the lockers of everyone I didn't like, it was a fucking hoot
I decoded the locks where you can change the combo and I would change it so they have to get maintenance to cut if off😂😂 never opened lockers just change combos
My school here in northern Europe had nearly unpickable disc detainer locks, but the door itself was easy to swerve open by force with a bottle opener or other piece of metal without breaking anything, since they gave in so much.
Last year, the school's lockers had this "glitch" we all discovered. Basically, the locks wouldn't auto scramble right, so if you closed the lock, you could just turn the dial by one number and it would open again. A lot of people used that trick to get their lockers open fast if they were in a rush. Its probably why the school changed the locker locks this year.
Very interesting! Over 30 years ago, I wrote software for a company that sold applications to school districts, and we had an application that managed these multiple locker combinations. Some poor sod at the school district had to sit down with the book or printout or whatever and manually key in all five combinations for probably over a thousand locks, but once the data was in, it was easy to do the lock change every year (apart from the manual effort of physically stepping the locks to the next position). When our software printed student class schedules for the students, we just picked up the correct combination based on the student's assigned locker number. Not bad for a software stack written in COBOL, I'd say. Today, I imagine (hope) you just get a piece of software from Master with your lock order that preloads all that combination data for you, and/or a dump file that contains the data in a usable form.
My new job has these for some of their lockers. Being the genius that I am, I left the sticky note with the combination inside my locker which also contains all of my keys (car and house) Hopefully, this video and and the comments can help me get home tonight.
We had these on my highschool and just turning them randomly to all directions they would likely open in less than a minute or two. They're just deeply flawed.
Sometime during my high school years I figured out that all the combinations changed by 3 or 4 plus or minus every year. I could get in lots of lockers by my senior year. Friends told me old combos and I converted. :) I never abused my knowledge but found it humorous.
Years ago I worked at a large company and my locker there had a lock like this on it. One day something broke on the inside of the lock and the latch wouldn't move. My manager had to call someone from key control to come out (which took a while) and as I couldn't go anywhere as my keys were in the locker they had to keep me on the clock. He tried a few of the multitude of keys he had but none worked so he wound up drilling the lock off at the attachment points. I bought a padlock of my own and used that to secure the locker from then on (there was a place to put a standard padlock).
LockPickingLawyer Agreed. I didn't have a choice while the original lock was on there. For a few days I used some cheap keyed padlock I had at home until I could get to the store and buy a combo lock so I wouldn't have to worry about losing the key. I bought a Master Speed Dial lock. It worked well and after a while I was able to open it faster than any key or standard combo lock. I liked how I could set my own combo of any length, I had 6 "digits" set on mine (so 4,096 possible combinations if I did the math right). Have you opened a Speed Dial lock on the channel and if not could you? I'd especially be interested in seeing the body opened up and an explanation of the mechanism.

I dunno, in many jobs, having the equipment break down through no fault of your own so you can’t work but still have to be paid sounds like a win. Doesn’t work in lawyering, obvs.
One combination to my HS locker was 15 - 17 - 47, suddenly remembered shortly after watching the video and reading some comments. (It's been a long time --- I graduated in 1977.) I believe the offset between combinations on that one was either five or seven digits, not different each time, but the same spacing all round (I could be wrong here). The Master combination dials we had required turning to the correct third setting, and opening the door required lifting a slide. I was well aware that there was about a one-and-a-half digit slop in my dial. Whether or not that was typical at that school I don't know, but it seems pretty tight for a Master.
I worked in a harddware store several years back and there were two boxes of these locks on the shelf, where they had been for a long time. One day I caught the local locksmith in the store and asked him to explain them to me. He took one look at the boxes and told me the combinations and keys had both been lost and the school actually gave those locks to the hardware store because they couldn't use them. I went by that store two weeks ago and all those locks are still there. Interesting situation.
I lived most of my childhood and teenage years outside of the US. Lockers were a movie thing through out my formative years, and just like with most things regarding the American high-school lifestyle that I knew about, it was just a fantasy. I just had a backpack that I prepared the day before for tomorrow's schedule and to leave anything at the school intentionally was just something that you tried to avoid. Anyway, when I moved to the US to finish high school, I was given a locker for the very first time. Neat! At first I was kinda exited ("Wow, just like in those melodramatic TV series!" I thought), but ultimately I never ended up using it. I think there were three attempts of usage. The first two were trying to remember whether I should turn clock-wise or counter clock-wise to make it work and failing several times before the lock just opening without knowing exactly how, and by the third attempt I just realize that I totally forgot my combination. Moving from classroom to classroom was also new to me (back in my previous schools the tendency was the teachers moving from classroom to classroom), so I found running from classroom to locker -fight with the locker- to classroom a real hassle, and is not like I found the idea of leaving stuff in school very comforting. So, yeah, that locker that was given to me stood unused and empty for two full years.
My hs locker combonation: "Lift the lever and turn the locks dial right then left any amount you want, then turn it right until it unlocks" I don't think the deadbolts hold up very well and the things are never changed..
What I think is really crazy about this is that's my locker combo from when I was in high school. I loved it because it was so easy to remember, and then once you realized that you didn't have to be exact with it it made getting stuff out even easier. Then people started losing stuff out of their lockers, and I knew it had to do with how easy it was to open the lockers. Some people bought extra locks to put on their locker and others just stopped using them altogether. I didn't want to buy a lock because the school said that if they needed to search your locker, and you weren't their to remove your lock, they would just cut it off and they said they didn't have to replace it. I didn't have a lot of money so I needed to find a cheap way to secure my stuff. Our lockers had the pull tab on them as well to open them, so I was able to add a second layer of security by putting a medal cylinder from one of my pens in that space.
@@Cubeeeeeeeee haha that sucks hey those janitors can be handy. one time i told a janitor that i forgot my keys to my bike lock and i needed to go home urgently, so they got the bolt cutters out and cut the lock off for me. the funny part is it wasn't even my bike
@@bmxscape reminds me of my friend whose number-combo bike lock was broken by bullies and had to ask the janitor for help, I was with her. We both thanked the janitor for cutting the thing and I gave her my bike-lock since my bike was an old kids bike for maybe 7 yr olds even though I was 11
I mostly watch these videos because I love hearing people talk about their special interests/hyperfixations/random interests Also I love the sound of combination locks
I work at a highschool and we recently got a batch of locks with only the first combo given. I looked up this video to remind myself how to find the other ones. I was shocked (though I shouldn't be considering it's Master Lock) to find that of the batch of 50 there were only 2 different offset patterns. -5, -6, -8, -7, -24 and -7, -5, -6, -8, -24. One of those appears in this video and looking through our books of the older locks in the building they follow the same two offset patterns. You will also notice the final offset is always -24 witch I feel like means you have even better odds of brute forcing the lock. These things are such garbage.
They probably intentionally designed to have some buffer in the combination length because it’s kids using it and it’s more important they access their locker than have to worry about anyone picking it

These locks are incredibly hard to get open even if you know the combination, because the ones that are actually installed in schools haven't worked properly in 20 years.
At my school, it was the other way around. As long as you got the first number right and you were within about 7 of the second and third numbers, you were good. Several times I ended up learning on lock turn in day that I’d been using incorrect numbers that were just close to the real ones.
I started in the middle of the school year,so I got a pretty old locker. It jams a lot and I have managed it now.
@@nordbrah6611 I'm a senior in high school, and I've never even used my locker since 8th grade
We need to pay 50 dollars for our hallway lockers so I just use my gym locker for my stuff, we just have normal locks and I don't even use one since no one takes stuff (except for me taking locks lol)
I didn't have time to go to my hall locker, but my gym locker was a trip. I had to put the combination in exactly, but all of the numbers were slightly off. 40 was 38.5 and had to be exactly 38.5. And none of the digits were off by the same amount.
Lol I remember being able to shake the hell out of my Locker and It would open
We could just pull ours open
All we did is just hit them a few times
The lowest-skill of raking attacks
Yep, ours was one solid kick with the side of the foot against the bottom. Literally didn't know my combo the next 3 years of hs after I learned this.
This reminds me, when I was a youngin I was sitting in the halls at highschool, wasting time, and four kids came upon a random locker, ripped the locker door out, lock, hinges and everything and chucked it out a window.
i wonder if he uses keys to his house or just picks the doors
You probably wouldn’t want to pick ur own doors since there is always a chance to screw up the lock
@@NegevLord yes but he is lpl, he wouldnt rlly screw it up
His doors are damn near pick resistant. He showed us in one video that he has a lock with a feature that lets him know if someone tried to pick it and makes the door unlockable, even with the key, if that security feature is set off.
Good question.
I would not bother locking things at all if I had his knowledge. Imagine knowing your front door can be opened within 1-5 minutes - try to sleep comfortably with knowing that.
“Doesn’t require precision”
clearly he’s never encountered one that’s like 20 - 30 years old and had to input the combination 6 different times the exact same way but for some reason doesn’t decide to open until the 7th
Ikr it's a small thing but proper working lockers are a huge quality of life improvement but nope let's buy 20 tv to put in hall ways well never use

And sometimes you have to get the combination wrong in order to open the locker but maybe this just happens to me
When I was in HS, me and my friend made a key for the back of the combination locks. It was pretty simple. We filed down old house keys until they would fit the keyway. (we were into locks and keys so we had a collection) Then filed a little more and a little more until it would open the locks with a little bit of upwards pressure. Not a perfect fit, but good enough when you knew the simple trick. I was never a thief, but I did get some pleasure in messing with the faculty. The teachers had a bank of lockers and other cabinets they used for storage. They would use old student locks and flip them around so the back faced forwards to facilitate easy access with the key. I would stealthily open them and flip them back the 'right' way. It made me smile anyway. I'm old--these were the days well before video surveillance of everything.
So basically just bump keys for raking attacks, right?
@@thinkiamsad Not a bump key. One that was filed close to the correct bitting. You just had to push it up slightly. We didn't have a key blank so we filed down old house keys that had similar warding until they fit the keyway, then filed some more.
With the right slight of hand, I've found that you can still get away with this kind of thing :)
Is a bump key different than a jiggler? I was thinking it sounded like you made a jiggler until you said it wasn't a bump key.
As a student going to Freshman year of HS this September; at my school we only have video surveillance at the entrances and exits.

manufacturer: our lock has 125.000 possible combinations
LPL: actually its 400
...unless you already know one combination (eg. know the student that used that locker before). Then it's just 50 possible offsets (0 included in case noone bothered to change it) - with the low precision, 25 tries maximum. And since 5 offsets must add up to 50, if you know the combination was only changed once... you almost always need to try a SINGLE-DIGIT number of combinations. That's mere seconds of playing with it, and you have your old locker back. Boy, truly Security with a capital S...
Good thing this thing is likely to be old and worn out in reality. Anyone trying that may easily miss the right combination, keep trying and give up, just because even the right one hardly works.

@Robert Slackware why do you have that many keys lmao
At my high school, the locks were one of three possibilities:
1) The locker won't open even with a master key.
2) The locker would open if you just bopped the locker lightly.
3) You could open it in 2 seconds with a quarter.
And the teachers would still complain that we wouldn't leave our phones in our lockers. XD
In mine, it was a case of seeing who used their locker. If someone used their locker, they’d definitely jammed the latch with a pencil or pen and you could just pull the handle, and if they didn’t then you didn’t have any reason to get in their locker
Ik this is late, but ima post; for us, people just put pencils in a certain part in the lock or whatever, so it wouldn't lock and would slightly be open because of just how B A D the locks were. Even if you DID get the combo right, it wouldn't open. Heck, one time someone ended up punching and denting their locker in rage because it wouldn't open.
@@redhero6377 Reading this stuff is pretty funny, no school I've attended has used lockers.
@@niero4201 You fr? Dang, you're lucky. For me I just put the code in normally, but then you had those kids that did that pencil thing. Then you had the rare handful that brute forced it.
Phones? You guys had it easy... Corded landlines were all everyone had when I went to high-school. Yep, we had to walk uphill, both ways, everyday also..
This explains how I opened my locker every day without looking at the dial. I'd just kind of turn it in a sort of correct way but super sloppily. Apparently no precision needed
lol
My Master Lock combination on locker at work is the same way. I can be off by 2 to 3 numbers on all 3 and it still opens. lol I never understood how that could be until today when I watched this video.
@@BIGgamez78 The ones we used to have at work (in govt) were really precise. You couldn't even be one notch out.

I always carried everything in my cinder block of a backpack lmao. Didnt even bother remembering what my locker number was
books were in backpack, everything else was in my jacket pockets(stupidly big pockets, made it weight like 10lbs alone)
Did the same. In my opinion if you found something worth stealing in my 80 backpack you could keep it.
In my HS we're not allowed to take our book bags around to our class, Im guessing for safety, One of my friends got detention for taking his around for a not puting his backpack in his locker for 4 days in a row.
My senior year I forgot where my locker even was, let alone the combination. I don't even remember if I had anything in it. I opened it once...

Why bother writing down the third number? The real third number is turn it till it opens.
True, for the sports I guess?

Idk man, me and my locker have a love-hate relationship and sometimes it won't give me shit until I've spent a good 10 minutes on it
Funny how my teachers always said "it's impossible to brute force these locks"
I feel like I should clarify that I mean brute force in the sense that you can’t try every combination in a reasonable amount of time.

@@moonsoul-nightcore8177 on my way to steal an electric drill from the shop class and just remove it from existance
I always just whacked the locker with an open hand and it would pop open. A lock is only as secure as the attached object.
Teachers have a lot to learn
The teacher either was told that by someone they assumed to know better than they, or, more likely, knew that it could be brute forced, but told you it couldn’t be done so that people wouldn’t try it.
The two high schools I've been to in Canada, we've never had these kinds of locks on our school lockers. You always had to bring your own lock (or buy one from the office for like 2 bucks), and then they had every student just fill out a little sheet saying which locker number was yours and what your lock combo was (everyone got to hunt around the school and just find a locker with no lock on it, and choose the one they wanted first-come-first-serve style, which was kinda fun tbh).
And then, if you forgot your combo or whatever, they just had a big-ass pair of bolt cutters that the janitor was always more than happy to go retrieve lol
Ive never seen combination locks on lockers, where i live (try to guess) all the lockers have key locks built into the door
I remember that when i managed to drop my locker key into the bottom of my bag, i was amazed that one of the staff carried a key on them which was able to open my locker
(I generally just had my PE kit in my locker, and sometimes i put my school bag in there as well during lunchtime as we were not allowed to take our bag into the lunch hall, and sometimes i had cookery ingredients in the locker, in which case i would have to leave my bag unguarded outside, especially after the fire alarm incident that happened as a result of bags in the hallway, and there was a one way system, so to enter the dining hall you had to go out and walk around the outside of the building, and then after leaving your bag outside the door, go in through the door into a hallway, and at the end of the hallway head through the door on the left, and when heading out of the dining hall you had to go straight ahead instead going along the corridor on the right)
In America, our middle schools are like that. You brought your own padlock to school on the first day. Don’t remember having to write the combination down for teachers, though. We did get assigned lockers with these locks for the locker room, though.
Middle school and the first year of high school, we had locks a lot like these, though a little different. I forget what number the dial went up to, but the tolerances were such that you could be ±2 on each number and it would still work. Also, IIRC the third number _did_ matter, because you could turn past it and the lock would re-close.
While I was in high school though, the school got added onto and remodeled, and all the lockers were replaced. Instead of installing permanent combination locks, the school issued combination padlocks -- presumably with the little keyhole in the back keyed the same (or to one of the same few keys). At the beginning of the school year, you'd pay a deposit of several dollars and get your lock. And at the end, you'd turn your lock back in and get your deposit back.
Still cool to see how the combinations are changed on the installed locks. I'd suspected it involved holding the button on back and turning the dial, but didn't know the details. I knew they changed the combinations over the summer, but hadn't realized they probably rotated it between several different ones -- much easier to change hundreds of them this way!
@@AaronOfMpls
If passing 3rd digit caused a reclose, if the lock was as cracked then apply slight opening force on the door so that when the bolt slid out of the way the door would open, or become very hard to turn in which case you just turn it a bit-try to open-repeat until door opens- don't need to know the last digit.
@@ferretyluv Lol you can't really speak for one of the world's largest countries and just assume it's the same everywhere. Especially with every city and county having their own school system. That's not even close to the standard here.
Still more secure than the locks my highschool used. I used to shim mine with a piece of super cheap plastic. It was actually probably faster than opening it with the combination. Would have been even faster if I used something metal.
mine would open if you hit the locker
@@luxzartheglorious the fonzie of lockers.
I’ve had a few lockers before which would pop open if you gave them a good whack. Then the others could be easily raked open in seconds. But they did have only about a 1-1.5 number area around the proper combo. Do they were quite good in that respect.
The lockers at my middle school had a plastic locking mechanism, so after repeated use they wouldn't even close properly because the metal catch had carved a notch through the plastic locking lugs.
@@luxzartheglorious my best friend in middle school had one like that but you had to kick it extremely hard to make the magic happen. He eventually broke his foot after doing that every day for months.
Here is the real bypass at my high school: hold up the unlock latch, bang the locker with your closed fist or palm of hand, cheap flimsy sheet metal plus terrible tolerances on the lock lack means you can open the door faster than even a key. After I realized this I literally forgot my combination after the start of Junior year. It worked on every locker I was assigned.
I did the same thing my senior year since I didn't actually use my locker often enough to remember the code.
I also coincidentally stole a lot of things from people's lockers that year.

The important thing to remember with these locks is that the odds of school admin actually changing the code (if they even know how) is about -14%

Esp geeky pre teens.
Tooootallly unrelated.
A gymbag is no fun but atleast flexible enough to allow some movement
When I was in HS, many years ago, the offset was 90 degrees, which I figured out because I couldn't picture the administration keeping accurate track of thousands of combos, so I knew there had to be a pattern. It seems I wasn't the only one to figure out the 90 degree offset so Master had to add a bit more complexity.
Interesting. Having 90 changes is criminally lazy. The offset is just notches in a disc. Having random offsets is just a matter of punching the notches in different places.
My reasoning at the time was that they just turned the dial 90 degrees wrt the guts. I.e. no offset disc. And to be fair, I have no idea who the manufacturer was.
Pretty sure you are right dave. It just allowed the front dial to slip and click into place in a second position, meaning the combination was exactly the same, but the dial face was cosmetically turned.
You do the best vids!
So, you mean the possible combinations for the lock were one-quarter of the disc, followed by same, followed by same? So with 50 numbers you'd have 13 combinations? That's pretty pathetic.

Alex Jamieson My school still gets us buy locks. Not a big deal, a pair of cutters can easily cut any common locker lock.
Alex Jamieson my school made us buy one as well, but we had to give the combination to a teacher. Which didnt mean anything since you could just swap the locks.

Preach
Step one: plan your attack on an unused locker
Step two: try 5-10 different combinations throughout the day as to avoid suspicion
Step three: repeat on the next day until locker opens
Step four: ??????
Step five: 2 lockers lmao
Anyone who knows where your locker is would find it suspicious. Also anyone who knows that that particular locker is unused.
Having the last position of the lock literally be functionless is inexcusable for anything purporting to be a "lock". When I was in school I was a relatively upstanding kid, but knowing what I know now, so much mischief would have happened. I still have one of my old combination locks with the master key cylinder on the back.
htomerif its because the last is mostly just a pulling action type thing
Even with a combo padlock, the last number is essentially meaningless (though not quite), as you can just quickly pull up and down on the shackle as you run down the numbers trying to brute force them. (If you pick the wrong third number, it's not like it resets or anything.) I had a method with early-mid-90s Master padlocks that gave me the middle digit of the combination, and brute forcing them was a snap, as you went up by two for the first digit, dialed in the second digit, and then just shook the lock/shackle up and down as you dialed down the last digit. I brute forced about a dozen of those within three or so minute (each).
I figured this out while I was in high school too, just a couple months into my freshman year I stopped even remembering the last digit and would just do the first 2 and turn till it opened
This is how the lockers at my high school were, all of the locks had a master key in the back and were all the same key, between the gym lockers and the hallway lockers. Each school year they'd take all the locks off and redistribute them, and then at registration you'd get your new combo (But you kept your locker all 4 years). My junior year someone got ahold of the master key, blocked one of the doors that never got checked, and came in on a Saturday and took all the locks off, and then put them all back on different lockers. So come Monday morning, nobody in the entire school could get into their locker, and the only way to look it up was with the code off the back of the lock.
Andrew Bowers that is a batshit insane system though. The other way around - keep the lock, change the locker - would seem to be much more useful. Or do you regularly have situations where a student and the school both think he’s gonna come back next year, and then they don’t?
I still remember my locker combination from 7th grade back in 1982. 17 - 35 - 03. I've often wondered what great things I'm not accomplishing because my brain is cluttered with such things.

Sweet
Imagine if you stopped a school shooting and then had to explain how you looking inside their locker
I had the combinations to every single locker in the whole school. After opening a couple I got bored and did absolutely nothing with my new found super power after that.
Must have been one high tech pick to involve more than one person to construct...
I worked with these locks before, but the version we had had some sort of way to make it so that if you don't turn it to the final digit purposefully before twisting it further, it would just reset. There was still a pretty wide tolerance and if you just twisted it fast with decent force, it still didn't matter what the last digit was. But it did seem to be a little more secure than this one, if it was only marginal
Heh, never once had to input the combo on a locker - just lift and kick the bottom of the locker (door part). The door would vibrate enough to simply skip off the hook or slot the bolt slid into. Could open any locker, after doing enough time (bout 1/3 of a school year) the hook or slot would have eroded away enough to only require a semi forceful palm strike near the lock (technically the hook or slot on the other side) to open, no lifting required.
Was very interesting to finally know what that button on the back was for though!

7 years of school (200*7=1400 days)
assuming 4 opens per day (4*1400=5600 openings during school)
Work:
33 years of work 49 weeks per year (33*49=1617 weeks)
1617 weeks 5 days a week (1617*5=8085 days)
assuming 2 opens per day (8085*2=16170)
Total:
16170 work opens and 5600 school opens (16170+5600=21770)
21770 cents shuffle the decimal $217.70
assuming $15 dinner plus 8% tax (15*.08=1.20+15=16.20 per meal)

@Alter Kater what else would you listen with?
This lock brings back so many physically painful memories. I had one of these on my old gym class locker from back in the 7th grade. I nearly had to twist my arm out of socket just to open the locker. I clearly couldn’t do that now as Arthritis has set in since then.
I never had to remember my combination back in high school. All I had to do was turn the dial back a few numbers to the last combo number, and it would open right on up. It definitely made those four years of passing periods much easier.
My middle school had regular combination locks, not ones with deadbolts. I vaguely remembering hearing about a trick where you just turn the lock around on it's side and slam it hard, and BAM it opens. Public schools are never known for buying top quality for their student's security. I also remember the prank where someone could undo your lock and turn it around facing the locker so it was a pain to open.
Can confirm that. Worked building lockers for a couple summers and learned how to open them with a firm kick or whack
I really appreciate how this video is less of a challenge and more informative.
This is one of a number of reasons I never kept anything of importance in school lockers.

Some schools are out here have lockers that come with locks?! I had to buy my own, but luckily could keep track of mine all four years.
Only school I've ever been on that had any lockers at all was kindergarten, lol.
At my school, half of us don’t even lock our lockers, we just turn it very slightly before it locks, so it’s shut but not locked. I bet if you go along a wall and check every locker, you’d find that many of them used the “locker trick” bc we’re too lazy to open them 😅
At my school the locks can be shimmed from the inside with a pencil or some other stick, and like half the students just shim their locker.
At my middle school, if you input the combo before closing the door, the latch wouldn’t catch, so you could just open the locker.
I trolled people by spinning locks and sometimes they get locked out because they forgot the combo. "Spin spin spin"

I was amazed with all the features of this simple looking, everyday lock but LPL has shown me much about it that I hadn't figured out even with some instructions. Thank you for this great video.
Glad it helped. 👍 Have fun with yours.
Magic Locks I never sent you the change instructions or your next combos did I? Let me know and I’ll email them
I remember that my high school had padlock style locks with the same type of dial as these. Because they were so old, you could figure out the combination by turning them slowly and listening for where the dial 'caught'. Was quite useful when you'd just come back from break and forgotten the combination.
Great picking and decoding brother,thanks for the review
Has someone built a computer controlled stepper motor gizmo that will work through all of the possible combinations (reduced by the shortcuts described in this video) to make quick work of automatically opening one of these? That would be neat to see in action.
Are you talking about samy kamkars video?
LOL. I should know better than to ask an obvious question without bothering to do a quick search for an answer first. Found the video, thanks.
lol
I'm sure you can do it easily with an optical rotation sensor, a couple motors,and an arduino.
Although it's not mechanically going through combinations, thieves use laptops to run through code combinations to get around new car security and ignition interlock systems.
Shit bro back when I was in school you could just jig (just yank repeatedly) the lock and it would open, always did it but never stole lol
ChromeEnthusiast lmao that’s funny
The real picklock trick is to twist the little “OCCUPIED” sign to “VACANT” on the wheel, and make your friends shitting experience much easier.
I was too lazy to put in my combination every time, so I rigged my locker to open from just jiggling the handle. other people I knew did the "set the first 2 digits when you leave so you just have to put in the last when you get there", so anyone could've just walked by, pulled up on the handle and spun and it would open. high school kids are dumb
@@darkmagician1184 I guess I'm old now...what would one take from a locker in the 90-95 time frame? No cellphones, no laptops (not the small ones...lol), maybe a graphics calculator and some text books. I guess kids have too much now like iPhones and laptops, and tablets.
@@Meekerextreme Gameboys, Sega Game Gear, Walkmans, etc.
thanks man,now i can finally get into stacey's locker :)
Aspiring akyat bahay boy here! super helpful vid.
When I was in school, half the lockers had a combo of "Kick and Yell!". I don't miss those days...
I do have some vintage lockers in my garage (inherited through in-laws)... but none have locks on them (they were used with padlocks). Thank goodness!
You are a genius to figure this out. As for me, (thanks to your video's) the only number I need for this combination lock is "22" which is the caliber I would use for the Ramset !!! LOL
nacra60na 🔫🔫🔫🔫🔫 😁😁😁😁😁
That would likely just jam the mechanism.
Nice to know considering this is the exact lock my school’s lockers uses.😉
“Now here’s how you break into lockers at your high school kids” haha dudes a savage his cold delivery is funny as fuck.
Sweet, now I can finally unlock my locker in all the dreams I have where I'm back in high school.
Amazing video! Keep them coming! Thanks!!
🤙🏼🤙🏼🤙🏼
15 years later and i still remember my highschool locker combo ... heh
That’s impressive.
I'm in school right now and I can't remember my combo👌
28-34-04 have fun with scraps of junk paper and wrappers lol
22-32-2
mine was far too easy (12 years later)
well, i still remember my public phone pass.... and it still works lmao i use it once a year
The first two combination numbers were my sixth and seventh grade combinations to the digit... which leads me to believe there is a lot more commonality between a set of locks at a given campus than might be desirable for security. For administrative logistics on the other hand... beautiful.
This reminds me of when I bought 300$ worth of those circular Masterlocks that have the really hard to access shackle, and put them on the lockers of everyone I didn't like, it was a fucking hoot
I need to do this.
I decoded the locks where you can change the combo and I would change it so they have to get maintenance to cut if off😂😂 never opened lockers just change combos
Your problem solving methods are inspirational. thanks.
My school here in northern Europe had nearly unpickable disc detainer locks, but the door itself was easy to swerve open by force with a bottle opener or other piece of metal without breaking anything, since they gave in so much.
Shoutout to my high school combo. It was 3-7-1.
My friend ELI just died. He lived by 173. Left under a cougar wheel
I had a combo of 0-3-0 once
Thats a bad combination and an ugly one atleast you didnt get 0-0-0 or 6-6-6 or 49-1-49
One of my gym locker combinations had been 5-10-15
3 17 5
Last year, the school's lockers had this "glitch" we all discovered. Basically, the locks wouldn't auto scramble right, so if you closed the lock, you could just turn the dial by one number and it would open again. A lot of people used that trick to get their lockers open fast if they were in a rush. Its probably why the school changed the locker locks this year.
Very interesting!
Over 30 years ago, I wrote software for a company that sold applications to school districts, and we had an application that managed these multiple locker combinations. Some poor sod at the school district had to sit down with the book or printout or whatever and manually key in all five combinations for probably over a thousand locks, but once the data was in, it was easy to do the lock change every year (apart from the manual effort of physically stepping the locks to the next position). When our software printed student class schedules for the students, we just picked up the correct combination based on the student's assigned locker number. Not bad for a software stack written in COBOL, I'd say.
Today, I imagine (hope) you just get a piece of software from Master with your lock order that preloads all that combination data for you, and/or a dump file that contains the data in a usable form.
>COBOL
Man I feel sorry for you
Wow, that is exactly the same tech and gate size they had 80 years ago.
Richard Feynman would have a field day with that.
“Peterson Flat 5” was my favorite funk band of the 70s
My new job has these for some of their lockers. Being the genius that I am, I left the sticky note with the combination inside my locker which also contains all of my keys (car and house) Hopefully, this video and and the comments can help me get home tonight.
We had these on my highschool and just turning them randomly to all directions they would likely open in less than a minute or two. They're just deeply flawed.
Sometime during my high school years I figured out that all the combinations changed by 3 or 4 plus or minus every year. I could get in lots of lockers by my senior year. Friends told me old combos and I converted. :) I never abused my knowledge but found it humorous.
Thanks for teaching me how to pick school lockers! :-)
It may have been a longer video, but I definitely enjoyed seeing the breakdown of the logic inside
Many Master combination locks can be opened using CCW-CW-CCW rotation instead of the common CW-CCW-CW rotation. Is that true of these locks too?
I don’t think so. However, you can rotate through the 5 preset combinations in reverse order by going CCW.
Years ago I worked at a large company and my locker there had a lock like this on it. One day something broke on the inside of the lock and the latch wouldn't move. My manager had to call someone from key control to come out (which took a while) and as I couldn't go anywhere as my keys were in the locker they had to keep me on the clock. He tried a few of the multitude of keys he had but none worked so he wound up drilling the lock off at the attachment points. I bought a padlock of my own and used that to secure the locker from then on (there was a place to put a standard padlock).
Always a good idea to use your own lock... if it is intelligently selected.
LockPickingLawyer Agreed. I didn't have a choice while the original lock was on there. For a few days I used some cheap keyed padlock I had at home until I could get to the store and buy a combo lock so I wouldn't have to worry about losing the key. I bought a Master Speed Dial lock. It worked well and after a while I was able to open it faster than any key or standard combo lock. I liked how I could set my own combo of any length, I had 6 "digits" set on mine (so 4,096 possible combinations if I did the math right).
Have you opened a Speed Dial lock on the channel and if not could you? I'd especially be interested in seeing the body opened up and an explanation of the mechanism.

@@tallman11282 is the speed dial the d pad like lock? Yeah he did a video on it.
I dunno, in many jobs, having the equipment break down through no fault of your own so you can’t work but still have to be paid sounds like a win. Doesn’t work in lawyering, obvs.
brings back memories of 8th grade and first combination lock. some tense times.
Past tense? :D
lol
At its core, this is a fascinating piece of engineering.
One combination to my HS locker was 15 - 17 - 47,
suddenly remembered shortly after watching the video and reading some comments.
(It's been a long time --- I graduated in 1977.)
I believe the offset between combinations on that one was either five or seven digits,
not different each time, but the same spacing all round (I could be wrong here).
The Master combination dials we had required turning to the correct third setting,
and opening the door required lifting a slide.
I was well aware that there was about a one-and-a-half digit slop in my dial.
Whether or not that was typical at that school I don't know, but it seems pretty tight for a Master.
I worked in a harddware store several years back and there were two boxes of these locks on the shelf, where they had been for a long time. One day I caught the local locksmith in the store and asked him to explain them to me. He took one look at the boxes and told me the combinations and keys had both been lost and the school actually gave those locks to the hardware store because they couldn't use them. I went by that store two weeks ago and all those locks are still there. Interesting situation.
I lived most of my childhood and teenage years outside of the US. Lockers were a movie thing through out my formative years, and just like with most things regarding the American high-school lifestyle that I knew about, it was just a fantasy. I just had a backpack that I prepared the day before for tomorrow's schedule and to leave anything at the school intentionally was just something that you tried to avoid. Anyway, when I moved to the US to finish high school, I was given a locker for the very first time. Neat! At first I was kinda exited ("Wow, just like in those melodramatic TV series!" I thought), but ultimately I never ended up using it. I think there were three attempts of usage. The first two were trying to remember whether I should turn clock-wise or counter clock-wise to make it work and failing several times before the lock just opening without knowing exactly how, and by the third attempt I just realize that I totally forgot my combination. Moving from classroom to classroom was also new to me (back in my previous schools the tendency was the teachers moving from classroom to classroom), so I found running from classroom to locker -fight with the locker- to classroom a real hassle, and is not like I found the idea of leaving stuff in school very comforting. So, yeah, that locker that was given to me stood unused and empty for two full years.
My hs locker combonation: "Lift the lever and turn the locks dial right then left any amount you want, then turn it right until it unlocks"
I don't think the deadbolts hold up very well and the things are never changed..
Way to go mate
Who knows how many kids lives are going to be made that bit more miserable thanks to you uploading this.
I was picking these in high school with concrete scraped street sweeper needles. Fascinating about the offsets though.
Ur so good you could probably figure out the combination to my heart.
is it 80 08 13 ?
XD
Glad to see ya back LPL.
What I think is really crazy about this is that's my locker combo from when I was in high school. I loved it because it was so easy to remember, and then once you realized that you didn't have to be exact with it it made getting stuff out even easier. Then people started losing stuff out of their lockers, and I knew it had to do with how easy it was to open the lockers. Some people bought extra locks to put on their locker and others just stopped using them altogether. I didn't want to buy a lock because the school said that if they needed to search your locker, and you weren't their to remove your lock, they would just cut it off and they said they didn't have to replace it. I didn't have a lot of money so I needed to find a cheap way to secure my stuff. Our lockers had the pull tab on them as well to open them, so I was able to add a second layer of security by putting a medal cylinder from one of my pens in that space.
That was a nice refresher,back for a rerun😀
Thanks 🙏🏼 and may you also have a nice 👍 day!
My locker is broken and just opens
I'm 3/4 done with the year and I dont know my combo
Ronnie Basnett yo same
Update: I think a janitor fixed it and I've been locked out for a week
@@Cubeeeeeeeee haha that sucks
hey those janitors can be handy. one time i told a janitor that i forgot my keys to my bike lock and i needed to go home urgently, so they got the bolt cutters out and cut the lock off for me. the funny part is it wasn't even my bike
@@bmxscape reminds me of my friend whose number-combo bike lock was broken by bullies and had to ask the janitor for help, I was with her. We both thanked the janitor for cutting the thing and I gave her my bike-lock since my bike was an old kids bike for maybe 7 yr olds even though I was 11
@@bmxscape yeah but when the kid who owns the bike comes they will figure out it was you because janitor will recognize you
That one was really good. I enjoyed all your figurine out. I wish I knew that in school I wouldn’t of forgot my locker number. LOL
I mostly watch these videos because I love hearing people talk about their special interests/hyperfixations/random interests
Also I love the sound of combination locks
I work at a highschool and we recently got a batch of locks with only the first combo given. I looked up this video to remind myself how to find the other ones. I was shocked (though I shouldn't be considering it's Master Lock) to find that of the batch of 50 there were only 2 different offset patterns. -5, -6, -8, -7, -24 and -7, -5, -6, -8, -24. One of those appears in this video and looking through our books of the older locks in the building they follow the same two offset patterns. You will also notice the final offset is always -24 witch I feel like means you have even better odds of brute forcing the lock. These things are such garbage.
They probably intentionally designed to have some buffer in the combination length because it’s kids using it and it’s more important they access their locker than have to worry about anyone picking it
