Bump Keys?

by **l0cked0ut** » 12 Oct 2005 19:55

Just finished watching a 90 minute presentation by people from the TOOOL organization in europe discussing bump keying and how amazingly easy it is. I was blown away. As far as I know almost any pin tumbler lock in the US can be beat like this if you have the correct generic bump key for the brand. Now, there are many bump-proof locking mechanisms, but they generally arent implemented anywhere except really high security places. For anyone here who knows about bump-keying, how much of a security threat is it really? It seems ridiculous how easy it is even to make the keys. Kinda has me worried

Just to say, spools are hard to pick, mushrooms are hard to pick. When your bumping, none of that is an obsatcle, and as Barry said it in the video, it's a dangerous threat to any pin tumbler lock security-wise. I bumped a Masterlock No.5 which was very hard to pick at first, and i bumped a Masterlock No.3 also, both in under 5 shots so..Yeah it's a big threat to me..

definately sounds interesting although its not something i see as being widely accepted in the picking community. It seems just more of a quick and easy way to gain entry, and it takes a lot of the work out of it. Scary thing is, any idiot with a few keys, a file, and a description of the 2 minute procedure can make himself a pretty dangerous tool. As for the bumping tool, that as well doesnt seem to need very precise construction in order to work

The key no being percise is not true, it needs to be cut at the same cuts as the original key. Of course I am talking of cutting a blank. I have a tutorial on how to make bump keys, it's in the Lock Picking - Manual Section, go check it out.

I think hey was referring to the angles, as I have seen some
keys that work quite well, but are disgusting to look at, as
far as precision and workmanship goes.

I'm itching to use the #9 space and depth key on the key cutting machine. :wink:

Do it, I wanna know if they work, I don't see why they wouldn't work.

Of course they'd work. A key with all #9 cuts (depending on your lock, for arguments sake, let's say the deepest cuts then :roll:

) is a bump key.

Well... remember too... that you also typically remove approx 1/32" or so from the shoulder and tip so that the key can be inserted slightly deeper than normal.

have any of you tried glue-gunning the shoulder in order to prevent damaging the lock face? On the toool video they suggest doing this but it seems messy.

BTW i tried finding a good file to do this but I couldnt find one. Also most of the keys I have dont have a triangular cut, its flattened on the bottom. should this affect the way i make them?

I had these pictures lying around, just never got around to posting them.

House key vs. bump key

"But wait!" you may say, "why is the entire shoulder missing?"

Well, I was bored, so I cut it off completely, and replaced it with part of a test tube stopper I had nearby, with a slot cut in it.

End result: when uncompressed, the rubber ends pretty much exactly where the original shoulder ended, but when bumped, it compresses, making it nice to bump with and preventing almost all damage.

Excellent stick.

One question, why was there a test tube lying around? :wink:

Chrispy. It's not polite to ask about that. Obviously it was a memento of his birth. :lol:
