This lock is a nightmare for every lockpicker. Because of the mechanism how the lock works, it appears unpickable to me. But judge yourself.

Nice video. GM has been using this design since the 1930s... I agree it can't be picked if it is mounted such that you can't tension the sidebar. unfortunately, there are tools that can easily decode it. There are lots of modern locks that operate on this principle, including that latest version of the Kwikset smartkey, and a whole bunch of surprisingly robust Chinese locks.
@Potti3146 жыл бұрын
Thank you. I think it's a great design for a pick-proof lock. The methods to defeat this mechanism by e.g. auto-jigglers were mentioned, but what do you mean by decoding? I can imagine that more precisely made locks with more wafer, etc. can eliminate the application of try-out keys. Just as you say, many modern locks follow this pattern. Is this the end of lock picking?

This principle can be overcomed by brute force like a classic scerwdriver attack in movies. So high security lock in China usually builded to be free spinning.

Actually this lock style appeared in 1969 for compliance with Federal safety standards which required locking steering columns for the 1970 model year.. The basic lock assembly dates back to 1967.. the previous GM locks going back to 1930 were briggs and stratton designed locks which used a single key way, in 1967 GM introduced the "Letter Key" locks where there were 7 different keyways.. labeled A, B, C, D, E, H, J, K. the pair would rotate every model year.. A,B keys were used for 1967, C,D for 1968, E.H for 1969 and J,K for 1970. in 71 they started over with the AB pair again.. this continued until 78 which would be the final year for the J,K pair. in 80 they settled on the CD pair which went until 85 or 86,, from 87 on they used the E,H pair on everything including the PASSKEY system starting in 1988 ... the only ignition lock that didnt use this was the 1991-94 Chevy Cavalier.. which used a double cut key.. in 1995 GM went to the 10 tumbler double cut key.. with this key designed phased out in 1996..

If you have the sensitivity of the prohibited lock picking lawyer fingers. You can individually pick the wafers without tensioning the core but the spring tension is divided between wafers so it is incredibly hard to feel the bar snap into place. Keep in mind that each wafer has to remain placed while the next is placed.

Nice video and explanation. I have a gm lock a friend gave to me but it didn't have the housing. I played around with it just pressing the bar in like you showed and didn't think anything more of it. Looks like if I had the housing it would have been a much greater challenge.

Thanks for watching. Yes, the complete lock must be taken into account when attempting to unlock what is secured with the lock. The mechanism itself is easy to overcome but the way the whole lock is built is relevant.

You can drill a small hole and apply tension on the sidebar. Or light tension CAN work but it's EXTREMELY hard. I had to fit two gm locks and we used jigglers to pick the ignition open. 68 keys on the chain but only went through the first 7 before it turned. :)
@Potti3146 жыл бұрын
I tried light tension and had no success. The hole might work but it's destructive and you need to know exactly the place. Not easy from the outside. I can imaging that tryout keys work well, given the bad precision of the locking mechanism.
@Jackcc56 жыл бұрын
Potti314 its not destructive its necessary if its only a small hole the lock will still work fine mate. these igniton often stuff out sometimes the only way to fix them is to drill out the side bar from the surface then replace the plug.

I saw this one on very old Ford Taurus (very rare in my country and region) , and I have similar working chinese (I think it's chinese) locker / desk drawer lock , that uses very similar design. And , it can't be - tensioned. When You try to tension it , You also tension all wafers , so , You can't put them down correctly. Key is cut on upper side , so , it's kinda unusual for this type of locks. It can be made to emulate this lock on video , by inserting small bars on 3 sides so only one can be unlocking one. I'll post a pics of key , core with key in it , and bible itself , as it has 4 sides for lock / unlock.

It´s owner tell me it has this system. Now I understand why I can´t picked.

I can understand your frustration. When I started working on this lock I had no idea when I couldn't set the wafers and finally gave up to solve the puzzle. Only after inspecting the guts I understand the reason. But now we are prepared for the next lock that behaves strange in the same way. I sent the lock to 'Lock Noob' and he was successful in opening it with the jigglers. It's because of the bad tolerances that the try-out keys work. So it's not a high security locks - but it cannot be picked.

@Jackcc56 жыл бұрын
it definitely is pick able ive done one of these before locks before. simply mark out where the side bar is then drill a small hole though the casting. then poke a tool though the hole to tension the side bar at the same time applying turning pressure then rake the lock with a city rake it will open. you may also beable to drill a hole from the serfice to allow you to tension the side bar. the reason why i was picking one of these is the owner wanted keys made to his ignition he also had a drivers door lock as well.
@Potti3146 жыл бұрын
I agree that this is possible. You tension the locking mechanism with that method and the bad precision makes this lock easy to open. But drilling a hole is kind of cheating and to some extend destructive. Also for me it would not be possible as I had no idea where the side bar is located in an arbitrary lock. Of course for a real application to get someone keys made, etc. the cheating aspect is irrelevant.
@Jackcc56 жыл бұрын
Potti314 its not cheating at all get the job done man. its not destructive its necessary the lock still works after drilling the hole if you wanna toy it and worry about drilling a small hole go head.
@stagepyro6 жыл бұрын
It's all about the springs... Also the shape of the gates and the edges of the sidebar are important. Weak springs on the wafers and strong springs pushing the sidebar inwards would make this lock an easy pick... GM as well as the chinese Golden Atom found the right balance of 'springiness'.
