(1152) Bjarne's "Denmarkian Gravity" Lock

- In this video I take on a hand-built challenge lock designed to defeat picking attempts.
Whipped videos highlight custom made locks sent to the LockLab as a challenge. They contain innovative modifications, unique security designs, and careful craftsmanship. Challenge lock design is difficult, to say the least, but many LockSporters excel in lock design and hand craftsmanship. Because there is such innovation among LockSporters, many manufacturers pay attention to the WHIPPED videos and incorporate the security techniques into their own locks.
There is only ONE RULE: The key must work. You are free to cover up the key to prevent me from seeing it until after I successfully pick (or fail to pick) the lock. I will make THREE 10-minute attempts (down from six 10-minute attempts in April 2018). If I fail to open it in that time, it will become a WHIPPED video. If you are interested in sending a challenge lock, please use this address:

Assa locks are made In Herlev on the Ruko factory. I have work'd there 15 years ago.
100% correct. This is the Ruko factory in Herlev.
I would stilll guess that this is a Ruko, not an Assa. This looks like the beefy Ruko padlocks, the only difference would be that it's not painted black with coloured stripes. Doubt it's an Assa.
Ade Larsen Wrong end of town ...
So Denmark as in DENMARK
The one, the only.
Sweet to see Danish people on Bosnian Bills channel ! (Oh yeah, we Danes love to hear our small country being mentioned)
You should do more RUKO locks for sure !
We are only Danish people here... i guess if he checks the statistics he will see lots of views from us :-)
Long live Denmark.
We're A LOT of Danes watching Bill do his thing. Damn.
Ja, mand. Vi da mange fra DK. :)
Cool key!
NICE!!!!
I had no idea that there were places called Denmark in the USA, that was confusing
Actually there's about 11 cities named Denmark in US.
Where can I get a table vice like the one you use?
It's the Panavise 350. Amazon has it for about $90.
It's Copenhagen like Curtis Hagen in white collar
As a machinist those grove doesn't look like threads to me but small circles milled into the core (look at 10:09). Why I think this is that I can't see an angle to the groves, they look perfectly square to the hole (instead of a threads spiral). While the difference might seem small a threads profile and slight angle will help with the feedback/counter rotation when a sharp edge grabs into them. Well at least theoretically :-)
To make these groves would require a small mill (CNC or round feeding) or a special tool. Or an insane amount of fiddling with a small 4-jaw in a lathe.
Or a dremel and a jig.
I saw that too. I was thinking a small mill and a boring-bar.
Possibly used a cut-down piece of a file as the cutter.
Built-in grooves at a regular interval, steel hard enough to cut through indifference.
That was my thought, tapping the holes is quite easy but square edged, milled undercuts will kill feedback. Easy enough on a CNC.
Those are ASSA/Ruko made groves. Here is an exploded view of that particular core with another format bibel: www.ruko.dk/da/site/rukodk/til-private/produkter/serie-600-og-500/serie-600-eksplosionstegning/
WineScrounger "easy enough on a cnc"
I think the short stout spring in #3 was meant to be the driver, with the coils engaging with the threading. It's something different though. Nice pick job.
Halløj Bjarne. Sikken en sjov lås.
I have been watching for quite a while I don’t understand how a lock works with a key retaining setup.
I have been learning picking also.
Thanks
I'm proud to be danmarkian ! :D
That would definitely be a scrapped Ruko padlock. There's a reason it says DISCARDED on the side. Anyways, nice video, Bill. Greetings from Denmark.
Love the word 'Denmarkian' Bill!
I'd swear I can see the spring in chamber 1 at 10:48
I don't think that's a spring but there definitely looks like there is something in there...
Instead of being "threaded", it has continuous circles going down the bore, in order the catch the edges of the pins and give a false feel that the pin is at the shear line.
I know this is quite old now but i saw that too.
I think it might be a grub screw. Put it just far enough in so the key pin will stick out just a little bit.
Are there any hollow pins?
I guess that would be hard to pick since your pick would be pressing hole?They should be really thin outer layer tho,so it would be hard to clip it.
With a strong spring I guess that would be a nice challenge
And if the ends of the hollow pins had slotted ends?
Think crenelations, like the notches on the top of old castle turrets!
The shear-line would work at the top-edge of the crenelations, of course.
When being picked, the tool might contact the top of a crenelation, or land in one of the gaps between.
This kind of unpredictable 'feel' could keep folks busy.
And if you are not careful, the thin material could bend, disabling the lock entirely.
Hmmm, if the gaps were just wide enough to 'capture' a pick and cause bending, where a key insertion would not, this could be a 'feature', and not a design weakness.
The lock keeps pickers out by setting traps for picking!
You got quite the idea there!
igor svakurac a hole wide enough to allow passage of the pick. So we gotta start with the key pins. If they aren't hollow, driver pins are irrelevant re: hollowness. So we have hollow key pins. Then we are going to have the hollow driver pins followed by the spring. (I'm assuming you were talking about the drivers being hollow.) The shaft for the pins is so narrow, try sticking a pick up through an empty lock cylinder. It's just not happening. Then, no matter how thin the material is cut, there's still a very definite edge that would be easy to lift with a pick. Then reaching the shear line is no different than any other pick. Plus if you get a really thin wall, there's no depth available for security cuts ie serrations, spools, etc. MAYBE some light indentations more akin to cheap Chinese serrations, but they'd be minimally effective, and still constrict the inside diameter significantly.
In short, for hollow pins, by themselves, that dog won't hunt. (My opinion only, based on what I consider logical progression of observational "analysis.")
Do you ever run the Kronos multipick on challenge locks or is that taboo?
I’m pretty sure anything goes with a challenge lock the thing is most challenge locks wouldn’t be a challenge if the electric picks worked on them lol
As yet another Dane watching this channel, this is a great video :)
Nice cursed lock from the Denmarkian people! 🤣👍
That lock sounds lovely when it opens.
I have a cheap lock, with a T shaped key. I think when I was trying to pick it, maybe it broke something inside. Because when I use it one way, like that lock, it doesn't turn. When I flip it, it works. But it works with a screwdriver, just barely touching the cylinder.
Very unusual pinning, but a great pick Mr.Bill
Could you perhaps make a short video once where you explain the functionality of the anti drill chambers? What makes them work?
If you mean the anti-drill pins, it's just a pin made of REALLY hard metal that's designed to fuck up a drill bit. He had a video where he tried to drill a lock (I think it was the motorcycle lock with the Stanley body and the tricked out core) with a load of really expensive bits, and ended up mangling a shit ton of them (Like 100 bucks worth of bits)
the pins in there are hardened steel, if you hit them with a drill, it can cause the tip of the bit to snap or jam, depending on how its hit, definitely wrecking the drill bit.
Drill takes the path of least resistance.
It will want to go around the anti-drill pin.... And axiomatically... Around the regular pins... Meaning you will NOT defeat the lock by drilling through it(pins will still be there).
I'd definitely call it a valid challenge lock- it just has a mechanism to force picking it in a given orientation, much like some locks' active elements.
Such a strange pinning altho since it took you 4 atemts he clarly did somthink right i think the thicker spring was desighn to be more like a coil to get snagged kinda like a thin spool but more effective an altho strange the gravity pin was a intresting idea, just my opinion proberly wrong but thats my take on it lol
Denmark WI, nice town
What did you learn in school today dear little boy of mine?
I learned that Denmark is a little land and in Denmark we do not understand
what the big world outside wants us for
and then we did not learn no more. :) Eddie Skoller.
Great job to both parties!
just a wild guess but maybe a shortened hole in the bible for pin 1 so if it is upside down it will not open but if right side up the pin falls into the keyway. put in the front to stop you from just using any key
bill, those parts on the key are from a lighter. got that one on my desk right now XD
Obscuring the key bow has some security value. It makes identifying the key (and lock) manufacturer or model more difficult.
But maybe not for a locksmith, lol, in which case the skull curses are probably more effective.
What security value?
If they have the key then security is already 100% compromised(typically).
Maybe so they can't SEE it?
lol true enough, if they have the key they can open the lock.
But if they can't identify the key blank (or more likely, the non-locksmith clerk at the key-cutting place can't identify the key blank) by shape then they "can't" duplicate it. It's definitely no "real" security. But every cheap trick (even voodoo skulls!) can help "secure" the lock better vs common people.
The 'skull' mask is a layer of childish wankery, not security.
A locksmith or a non-locksmith clerk at the key-cutting place would slip in blanks until they find one that fits anyway.
If you called it, I missed it; what pick did you use?
Great lock! Great pick!!!!!
The clicking is so nice to hear. Very satisfying sound
Very strange set up, but nicely picked!
He was kidding about the gravity thing right? lmao
My 2 favourite padlock companies
Thanks bill :) great video as always
love your videos
Bill wondering about round disc locks. Everyone picks these upside down. Wondering if there is a gravity deal in there. I can not pick them in a hanging position like if on a locker, but can pick it upside down.
I hope the maker of this lock shows up in the comments here to explain what the hell he was trying to do here.
He appeared 11 hrs prior to you. Bjarne Christensen
besides 2 special drivers and the tiny spring, it was just a normal ruko VT snowman cylinder. even the bitting looks stock.
Beautiful Ruko there Bill Drool !! lol
With a pin missing, for the lock to open either the bare spring must line up with the shear line or the key itself must push that sole pin all the way down until it's under the shear line, right? Guess it depends on the spring, whether or not it is nicely rounded and not too thin, whilst the cylinder may not leave too much wiggle room around it either?
Some people claim that there is no gravity. this is further proof that gravity is.:)
Amazing picking on such a very odd lock.
I did wonder if the anti drill pins at the front were free floating, cos they could be used to lock up the plug if they dropped down between the Bible and plug
Hello Bill.
I live 8 mile from Herlev In Copenhagen.
Love your Channel
Have a good One
That circle includes most of Copenhagen, about a million people...
Gotta love it, great vid
I like that key turning action. Nice solid ka-chunk-n' key turnin'
Hmmmm weird #1 & #3...
Obviously not Denmark as in a city in the USA SMH
I really like that you include the first intro and the current attempt
new sealand is named after zeeland a province in the netherlands.
"Byarn"
Don't have the money but Really Wana get to trying this it seems very fun and challenging. One day...
Go to lock-lab.com and browse around. Bill has a nice series on how to fabricate your own picks and tension wrenches. All you need are small hand files, sanding paper in varying grits and a wind shield wiper... and patience. If you can borrow a Dremmel style tool that will speed up the process, but it isn't stricktly needed. My guess is that you can be well on you way with $20... old locks can be traded for a family pizza and a six pack at your local lock smith.
Very Weird Challenge Lock....????
Very cool lock and another great video
Bill seemed frustrated with this one.
I keep rewatcging this video
A spring instead of a driver pin! That setup is destined to jam. Hard to even call it a lock.
Some of the "challenge" locks seem designed specifically for a tricky picking challenge ... but with mechanisms which wouldn't be generally practical in real-world usage.
Chuckle, yes a lock. It put his pick in lockdown. Lol
-sigh- everyone says wisconsin so weird....
Just started watching, what's the significance of threading?
to make the pins grab and catch when someone is picking it.
BB, do you ever do safes? Would love to see a series on gun safes to know how secure they are.
Arcticgun safes are just big safes.
gun safes are as secure as the company that makes them.
when we gonna see the quads? lol
What brand is that Cylinder? (Bible+Plug)
It's from the Danish lock brand Ruko, now part of the ASSA ABLOY Group and recently renamed from Ruko to ASSA ABLOY Opening Solutions Denmark.
Mmm OK nice video
I love video (252)
Commented
Nice!
Hi
Only you could pick a defective lock lol 😂
James Murphy it wasn't defective it worked perfectly.
I believe that indexing issues was a added security feature
"o
Denmark 🇩🇰🇩🇰🇩🇰
Greetings from Denmark. I laugh so hard when you said "denmarkian" (just so you know it's Denmark and Danish not denmarkian)
Of course, I was just playing around. Still, I'm sure there's SOMEONE out thee that thinks "Denmarkian" is correct...;) Just as I'm sure that someone believed the yarn about "New Zealand" being named after "Zealand"...
Wow en fed lås
Wiki says it's from Zeeland in Holland.
det samme her sjov måde han siger Bjarne på heheheh, like the vids BB, hope to learn enough to maybe some day pick a challenge @Bosnianbill
wiki is wrong its zeAland not zeeland, in danish Sjæl(soul)land(land-country)
hardly a challengelock, pins missing, all standard?
Cheating and not a valid challenge lock! Missing parts... Boo!
Daddypants11 The lock worked perfectly.
That is the only requirement.
Whether you are in Denmark, Iceland, New Zealand or Vietnam, gravity pulls objects towards the centre of the earth.
You know know that old zeeland is not in Denmark, right? It’s in the Netherlands. Copenhagen is not Amsterdam.
27th!
There's no pin or spring in chamber 1 because the key pin needs to freely fall into the chamber to prevent the key from opening the lock when it is inverted into the "locked" position at 0:57.
Yeah, I missed the part in the video where he explained that. Could you be useful and point me to that?
Could you send me some locks
