Bump Keying

There's a phenomenon arcing across the Internet that claims to make every keyed lock obsolete. It's called "bump keying" and it involves altering keys slightly in order to make them open any lock imaginable.

The idea is to cut the grooves a bit deeper, then simply tap the key as you are turning it to get the tumblers in the lock to bump out of the way, thus opening the door/padlock/safe. It's interesting, already there are sites making a killing selling sets of these keys, and people are losing massive amounts of money as insurance companies refuse burglary claims if there is no evidence of forced entry.

This foreign video explains the method and shows the process behind it, it's pretty sobering.
