 What is “Bumping”?

Burglars take a regular key and mill it down, creating a “Bump Key”. It is inserted into the lock and with a tap of a hammer on the “Bump Key” the lock opens. It’s so easy an eight-year-old can do it! The technique has been around for over 20 years and is spreading like wildfire thanks to the internet.
