What is bumping locks?
All cylinder locks rely on what is called a pin tumbler system, “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 to cause the individual pins to jump to allow the lock to be opened using a special key known as a “bump key”. The 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. Unfortunately, for the victims of this method of entry they then have the difficulty of claiming on their insurance as there is no visible sign of forced entry. Click here for a video.

The reason picking works for these locks is because they are badly made, or worn down.
