I believe on the back or something you can like detach the cams from the dial, at any time to set the combo and then reconnect and do it two more times to get the other cams
Good question! The specific lock shown here does not allow the combination to be changed, it such a mechanism is unusual for that type of lock. For combination locks with independent code wheels (where you key in a three or four digit combination using three or four code wheels), code changes are usually possible. This works by temporarily disconnecting the internal cams from the visible outer code wheels, allowing you to change the visible combination while keeping the internals in alignment. After setting the new code, the cams and code wheels are locked together again, so until the code is changed again, the internals will now align whenever the new code is visible on the outside.
That's pretty much how the creative industry works. They spend a year to make something you enjoy in one hour, and still get a bunch of people who think it's too expensive and maybe they should enjoy it for free.
You modeled, animated, and made this whole video in 60+ hours so we can enjoy 6 minutes of it? Damn! I give you respect and a sub for that! Absolute dedication.
Great explanation! One note I have at 4:40 is that the jolt from locking it often isn't enough to move the cams out of alignment, and so unless you turn the dial again to move them, there's a good chance your lock will just open if someone pulls on it
I watch all of LockPicking Lawyer without understanding anything about locks, so this video is extremely useful for me. At least, when he will post about combination locks, I will understand the principles of operation
@@fish4225 when you put tension on the shackle you will be pulling up the collar which gets caught in the gates. By pulling on the shackle you are also lowering the tip of the gate which can also get caught in the gate. Both of which would be noticeable. Though you do need to play with the tension a bit so it's not too strong or weak.
Wow, that was great! After opening a locker multiple times per day for all those years in school, I finally know how the locker combination locks works. There are so many things that we take for granted but don't know what is actually happening behind the scenes.
Yeah, till you make a small shim put it in where the latch is at. Then push down where you can push the latch in then pull while holding the shim down.
Really good animation. There's something you might have missed though, cos it's not that obvious. When you pull the shackle open, past where the locking lug is, the edge of the shackle retainer clip also knocks the combination rings and moves them all out of place. (That's why it's shaped a bit weirdly).
@@markylon They are mainly used in commercial situations and bought in bulk. For example, a company can provide locks for employee lockers with different codes but use the master key to remove any lock if needed.
This has been explained to me several times over the years but without a visual, my grasp on this concept was fuzzy at best. Thanks for the time you took to make this!
Thanks a lot for putting the effort to do these videos! Not only animating, but doing the research, modeling, editing... This is quality content right here. And of the best kind.
I'd rather work a minimum wage job stocking shelves than have to make a video like this. All the thought and effort that has to be done to make a video like this...no thanks. I'm grateful that there are other men out there who are willing to make videos like this just to entertain us.
One thing that was shown (but not talked about) during the 'how dial sets code' animation was the first disk having bumps/notches in it. I believe they are called 'gates' and their purpose is to make it more difficult to pick the lock by lightly pulling on the shackle, spinning the dial, and feeling for true notches to line up under the latch.
The lockers at my highschool had the locks built into the lockers and after putting in the first two numbers, twisting really hard clockwise would always grab he last one and force open the lock. I think the 3rd cam had to be connected to some kind of spring or coil as it could only twist so much before it would pop open the lock. It made opening other people's locks really easy as it was pretty easy to hear the first 2 cams line up and the third didn't matter because it would always catch.
Yeah, I've seen many of these things that in reality end up being two number combination locks. Never liked them for that reason. Sure, they did their job, but seriously, let's at least try.
@@bwhog Yeah, they are designed to be easy and cheap to manufacture and usually just used for low security stuff like lockers. They are good enough that the average Joe can't just open one up, but anyone who knows locks can get into them really easily.

Awesome man! You'll make a great teacher. No one can explain things as clearly as you. And as a bonus you give the vibe that learning is fun and is nothing to be intimidated about.

I've known how this works for awhile. However we had same combination locks but with a tiny key access on the back. The administration had the master key and could open it up whenever they wanted. I'm interested in seeing that. I opened a few locks like this and could figure out what the combination was after seeing it line up properly.
I’ve been studying in Faculty of engineering for 3 years none of my professors have showed me how things really work and you do it in minutes. It’s cool🖤
Very interesting. Love seeing how things work. I was always fascinated by machines and mechanisms that perform functions. When I was young I liked to take things apart but most f the time had difficulty with the reassembly. Parents were NOT real happy with that but then I learned how to repair things instead of just dis-assembling them. Now, everything is a diy project, lol 😆
Thank you Mr owen! I'm in 6th grade and never in my life have i ever used a locker. You helped me understand how a master padlock works. Thank you very much. :)
Great animation. My immediate first imstinct was "a thin sheet of metal pushed down the shackle should be able to bypass the lock then". Turns out, yes it does.
GREAT JOB! Who knew a simple combi-lock had so much going on inside it. Seeing it still looks like magic to me. At the 1:41 mark, I can see why a shim made from an aluminum can will open some combi-locks.

I saw the spring and could almost hear LPL shimming the lock lol. It's honestly kinda cool how LPL made a lot of people aware of the design flaws in locks, so that people can make more educated purchases.
Damn, I never even know that you have to go the opposite directions the next time. i was wondering before for example if the combination is 13-22-34, then I can just do it in one swoop. Just forget everything and rotate to 34 because you'll pass by the other two nonetheless. apparently, that wasn't easy as that. i learned something new today 😆

Very nice instructional video young man. I think you've got a promising career in instructional design (specifically eLearning) if you choose to go down the path.
Like many things in mechanical engineering, it is really clever and elegantly simple, and yet extremely useful. Not meant to be high security, it does its job quite nicely. 👍

@@fefrei One example of this that's readily available are the big Bell cable-locks for bikes (the 5-digit ones, not the smaller 4 digit). Once you undo the lock, there's a little collar that you loosen and it allows you to ajust the outer parts and change the combo. My targus Kensington lock does something similar with a flathead screwdriver when the lock is open.

I notice that these locks give a bit of freedom and +\- error when putting the combination in. It helps just in case you don’t know the exact numbers, or you want to go quick.
Mathematics is not the only field where "combination" is defined. More commonly, "combination" is used _similarly_ to the mathematical definition but more loosely, typically including permutations, as "permutations" is a term that is less customarily used by people who do not have a recreational/professional/academic appreciation for maths. The numbers on the dial don't indicate math, per se*, as it's just an application of the number line to create a series of uniquely referenced positions with minimal actual marking, using something people generally know. *You could use permutations to calculate how many different lock solutions are possible even if the dial had letters or hieroglyphs. TL;DR - the lock is named with the common use of "combination", not the mathematical use, because the common use is what people will commonly think of and, commonly, people do not give "permutation" much use.
Wow! I always wondered why I had to "clear the first number" before going to the second number; but didn't have to clear the second number before going to the third. This video "clears" all that up. Thank you!

Good question!
I'm pretty sure this style of combination lock does not have a way to change the combinations. Multi-dial ones might.
Great video but what changes when you change the combination?
Good question! The specific lock shown here does not allow the combination to be changed, it such a mechanism is unusual for that type of lock. For combination locks with independent code wheels (where you key in a three or four digit combination using three or four code wheels), code changes are usually possible. This works by temporarily disconnecting the internal cams from the visible outer code wheels, allowing you to change the visible combination while keeping the internals in alignment. After setting the new code, the cams and code wheels are locked together again, so until the code is changed again, the internals will now align whenever the new code is visible on the outside.

You mean *joined* ?
Never quite understood until now how these worked and never seen clearer more informative videos !!
"How does a combination lock work?"
*"I don't need sleep I need answers"*
this is fun because i was actually going to sleep until this video popped on my recommendations
Stolen..... oh well
What happen if you messed up?What does it looks like?
I notice that these locks give a bit of freedom and +\- error when putting the combination in. It helps just in case you don’t know the exact numbers, or you want to go quick.
I could never figure out these locks. Hated them
*jokes on you my school locker only use 2 combinations number*
nhanie fu** off
Okay, if you want to get the combination, try "69" you'll at least open 10 locks in 5 minutes.
iFlx_re lol
iFlx_re i doubt students pick their own combos, but thats funny
It’s actually called a perspiration lock. My math teacher told me that this year.
I suspect the teacher said permutation.
6 min of video but hours or days of research and work to do these videos ! Thank you for sharing !
Geniuses plan and invest their time inventing such creations so at the end some people simply forget the codes 🤦🏻♂️😂😂
Shouldn’t a combination lock be called a permutation lock as the arrangement of the numbers matter ?
Mathematics is not the only field where "combination" is defined. More commonly, "combination" is used _similarly_ to the mathematical definition but more loosely, typically including permutations, as "permutations" is a term that is less customarily used by people who do not have a recreational/professional/academic appreciation for maths.
The numbers on the dial don't indicate math, per se*, as it's just an application of the number line to create a series of uniquely referenced positions with minimal actual marking, using something people generally know.
*You could use permutations to calculate how many different lock solutions are possible even if the dial had letters or hieroglyphs.
TL;DR - the lock is named with the common use of "combination", not the mathematical use, because the common use is what people will commonly think of and, commonly, people do not give "permutation" much use.
Wow! I always wondered why I had to "clear the first number" before going to the second number; but didn't have to clear the second number before going to the third. This video "clears" all that up. Thank you!
