An attacker uses a bump key to force a lock on a building or facility and
						gain entry. Lock Bumping is the use of a special type of key that can be
						tapped or bumped to cause the pins within the lock to fall into temporary
						alignment, allowing the lock to be opened. Lock bumping allows an attacker
						to open a lock without having the correct key. A standard lock is secured by
						a set of internal pins that prevent the device from turning. Spring loaded
						driver pins push down on the key pins. When the correct key is inserted, the
						ridges on the key push the key pins up and against the driver pins, causing
						correct alignment which allows the lock cylinder to rotate. A bump key is a
						specially constructed key that exploits this design. When the bump key is
						struck or firmly tapped, its teeth transfer the force of the tap into the
						key pins, causing the lock to momentarily shift into proper alignment for
						the mechanism to be opened.
