bumping tubulars?

[jasontimmer]

does anyone think it would work to, or has actually tried, bumping tubular locks? the more i think about it, the more i think it should work, in theory. i just need to get a tubular cutter and blanks. im thinking you would need to take off a very very small slice off the tip, if any at alll, and since there's no shoulder, can forget about that. any thoughts?

While we're at it, anyone want to give foil impressioning a shot?

That's a neat idea. I have a tubular lock on my computer lock. I imagine 'bump key' isn't quite the appropriate technology though. Rather you'd want a cylinder attached to something springy (and, of course, a torque wrench). While applying torque, position the cylinder such that it matches up with the top of the lock and is pulling back on your spring (I'm imagining rubber bands could be used somehow). Let go and it slaps into the cylinder. As long as your torque is constant, a few tries and it should spin...

The parts you'd need:
Torque wrench
A cylinder of the appropriate size, that fits easily into the lock and is deep enough to depress the cylinders to the maximum height, plus some sort of hooks to connect to whatever elastic system you use
Elastic system

Actually, now that I think about it, it's more like a rubber band powered pick-gun for tube picks... But it does still run on the same theory.

Thoughts?

Its been discussed before and somewhere there is a long thread about it with all the differant suggestions and possabilities mentioned,

It has a very good chance of not working and i personally dont think it will,

It still remains untested thoguh as far as i know,

There were even tool designs posted on how it may be done,

I dont like the suggestion of this being in the public sections due to the vending machine thing but it is an interesting theory for sure,

[nezumi]

Don't vending machines have other security stuff on them to make it more difficult? I seem to recollect I looked at the ones near where I work and it wasn't a tubular lock with the pins revealed, it was something else more crazy.

[Shrub]

Well we arent going to get into the subject of them here but no, a lot of them do have a normal tubular lock,

shrub, is it possible/can you tell me how to get to the sections where this may be discussed? can you direct me to the thread where this was previously discussed?

[jasontimmer]

nezumi, can you draw me a picture of your idea? im still thinking that, since a "999" cut tubular key will touch the pins as long as its sitting firmly in the lock, that the metal itself might have enough "give" to it to transfer enough energy to open the lock, without having to shave anything off the tip. though, i bet it would be very difficult to keep the key seated in the lock, apply the torque, and bump the key at the same time. Oh, and what about this "foil impressioning" thing? i haven't tried impressioning yet, but yesterday went to wal-mart and bought a couple blanks. seems that when i put one into a lock, there's absolutely no room to "rock" the blank enough to make marks. what gives?

[Bud Wiser]

Vending companies are getting smarter. Most of the newer locks are much harder then the old tubes.

I would like to see the design plans for a tube bump key. I'm most interested how one would hold the tension while bumping

Seek and ye shall find. The information is all right there.

Bumping might break the lock.
You can decode/pick most of the locks pretty easily. As Barry Wels has shown us you can use a bic pen, or softer materials the same dimensions to impression the lock, and even if you can fully turn the lock open once you know you have it impressioned correctly you can make a key.
I personally believe your at a great risk of breaking a tubular if you try and bump it. Maybe I'm wrong.
