Lock Bumping
One threat that never seems to get away regarding home security is lock bumping.
LOCK BUMPING involves a method wherein you use a blank key is cut in a special way called the bump key. A BUMP KEY has all the cuts at its maximum depth. You slip it in. When a bump key is inserted all the way into the lock, it will be pushed out a little by the springs inside the lock until the pins in the lock comes to rest in the deepest point in the cuts. It won’t turn. The key will just ‘bump’ it in the right way and the lock key will give way. An amateur can learn this tactic easily.
It’s no secret that lock bumping is spread all over. Just give a person some bump keys and he can get in through any door. There are some expensive locks that can resist lock bumping, but the most commonly used locks can be opened with lock bumping.
