lever bumping

Not sure if i ever posted this vid on LP101, i couldnt find it...

Its a useful trick if you're lever lock suddenly wont open after its been a bit ropey. Usually worn levers or key issues.

As demonstrated by a local locky near me

No such locks anywhere in minnesota but I love to see stuff like this, thanks.

That's interesting. Of course it's not actually being "bumped" open like pin tumblers, but definitely interesting.

The principle is the same and if you could take a quick peek at a key you could roughly cut one by memory and employ the same methods...

Have they tried it with any other keys? For example a generic key cut to the 5 position?

Lever Bumping.. I've now seen it all.

@Josh

This is a technique for making a worn key and/or lock combination unlock with the proper key. It would be mechanically impossible to use a "555" ?!? key because lever locks do not have a shear line, so there is nothing for an inertial attack to attack.

Kind of like wiggling your car key when it sticks.
