Lock Bumping, Key Bumping
First introduced in Europe, professional and amateur locksmiths refined a procedure for knocking on a lock cylinder while applying slight pressure to the back of the lock itself. With the pins "jumping" inside the cylinder, the plug would be able to slide out freely and disassemble the lock quickly. The use of a "bumping key" was later introduced and was first recognized as a potential lock security issue sometime in the early 2000's. Lock Bumping and Bumping Keys are sweeping the Internet and world-wide
Lock Bumping and Key Bumping is characterized by:
- use of a lock bumping key to gain entry, bypassing the security of conventional mechanical locks,
- entry can be made in less than five minutes,
- use of a bumping key is easy to learn,
- the bumping key and "striker" are easy to conceal,
- lock bumping leaves no physical signs of forced entry,
- with little evidence of a compromised lock, your insurance company may deny paying for the claim.
