The term lock bumping comes from the fact that a specially cut key is inserted into a door’s keyhole and then bumped or tapped by a screwdriver or any other object, the bumping does force the pins in the lock to jump to what is called the shear line , and with very little torque applied to the inserted key, the lock is opened. Unfortunately, slightly more than 90 % of Americans still use cylinder locks which are vulnerable to lock bumping. It is also worth noting that when a bump key is used to gain entry into your home, there is usually no sign of forced entry. Fortunately, there are several ways of protecting yourself.
First, you need to check your locks for signs that it bump protected: depending on the brand, a small positive (+) or negative (-) next to the keyhole is all you need to see to know that you locks are bump free. Alternatively, you can either take your door locks to a locksmith or have him come to your place and install some special pins which will make it difficult to bump your door.
Alternatively, you can replace your current locks with either light or heavy commercial grade locks or install the high security bump and pick resistant locks which are currently quite popular since more and more people are getting aware about the danger they are exposing themselves to on a daily basis with those old style cylinder locks which are all vulnerable to bumping.
