"Pins" are set at different heights so when the correct key is inserted they are pushed up into a clear line to allow the key to turn and operate the lock.
The principle of bumping works on creating a kinetic energy causing the individual pins to jump, allowing the lock to be opened using a special key known as a "bump Key." This form of attack is prevalent across Europe and disturbingly 80% of the locks tested by an organisation in the Netherlands could easily be bumped within minutes – most only taking seconds.
