Did you know that it’s possible to unlock just about anything with a keyhole in less than a second without doing any damage to the lock? I didn’t either! All you need is a keyring full of ‘bump keys’ and a hammer. You don’t need any special training and you don’t need a lockpick set.

This video shows how easy it can be.

This is pretty scary. You can grab a set of five bump keys for less than $10 on ebay.
