Lock Bumping?!

The bad guys already know about this!

Yah, that's been a trick around for a long time. By tapping the key, it "bumps" the tumblers inside of the lock to their positions to turn the lock open, releasing itself instead of a key that fits the lock and the tumblers are pressed to open the lock.

Its the same idea as a pick set but using a key and a "tapper". That's why you should by the better brands than cheap stuff.

I may or may not have used this trick a few times back in college. Between friends losing keys, running maintenance on apts, and an affinity for practical jokes resulted inm alot of bumped locks. I've got medico 6 pin locks on every entry door. They're hard as hell to pick and very reliable.
