Bump Keys

Fine. As if we didn't already have enough to worry about, now it may hardly pay to lock our doors!

Seems some Danish locksmiths discovered the technique of lock bumping back in the 70's, but it's only within the last couple of years that the bump key and its application to opening easily most simple pin tumblers has been become widely known.

There are a number of videos on the net about how to make and use a bump key. Essentially, you just have to get a key that fits the lock you want to open and file it down a little, so it looks like this.


Of course, if you don't want to make these keys yourself, you can buy them ready made through the web.

Good article here: http://en.wikipedia.org/wiki/Lock_bumping

I guess it's time to get a Doberman.
