Lock Bumping is a specialized method to bypass pin and tumbler locks. This was invented for legal purposes; however certain entities access these tools for their own benefits. Lock Bumping is an attack technique to bypass locks which utilize special cuts keys. It is a very powerful technique, which conventional pin and tumbler locks often fail to withstand.
This technique works on the laws of physics. First, a specially cut key is put into the lock hole, then by using a certain type of object the key is struck or bumped. The energy henceforth is transferred to this through high impact forces on the pins of the key and lock for a few seconds and thus enabling experts to open the lock within that time frame.
