Lock Bumping - Spread the word to your clients!!!

Lock bumping is the term for a very common technique used to open pin tumbler style locks that are installed in over 90% of homes and businesses worldwide. A specially designed key known as a bump key is all it takes to open virtually any lock of it's type.

The Lock bump key (also referred to as a '999' key) is easily produced by simply filing down the points on a blank key or any other key designed to fit in the key hole of a particular style of lock. The points are filed to the lowest depth in each groove and very small ridges or elevations are left between the grooves, if the points remain too steep, the key will not enter or exit the locks key hole. The tip of the key as well as the shoulder of the key must also be filed down by about one millimeter.

Lock Bumping Technique  - very little skill is needed to master the technique of bumping locks, It's simply a matter of inserting the bump key into the key way of the selected lock and tapping the head of the key a couple of times with a small mallet, screw driver handle or something similar, while applying a turning motion to the key. Some locks can even bumped with a simple flick of a finger on the head of the key. The skill level required to open most locks with the lock bumping method is so minute compared to other lock picking methods that just about anyone including children can open just about any lock.

How Lock Bumping works - When the shoulder and tip of the key have been removed it enables the key to be pushed  deeper into the lock,. the bottom internal pins of the lock are forced upwards because of the slight elevations or points that were left standing on the key. Each of the bottom pins will transfer this upward motion to the next pin sitting immediately on top of it. The top pins are then forced upwards while the bottom pins remain in place. (The same effect is occurs in a game of croquette when you hit one ball with tour mallet that is touching another ball only the second ball moves) As the top pins are  separated from the bottom pins, the key cylinder can then be turned and the lock is will now open.

Preventing Lock Bumping - It's Ironic that more sophisticated manufacturing processes are in fact producing locks with cylinders that are actually easier to Bump because the pins are designed to move more freely and smoothly which is ideal conditions for lock bumping. Also these more sophisticated locks are often manufactured with hardened steel which make them less susceptible to damages that  might otherwise occur on a cheaper lock causing it to jam and remain locked.

High security Locks having pins combined with a regular tumbler mechanism will typically make bumping a more difficult task but not entirely impossible.Other security locks such as Electronic and magnetic locks or locks that incorporate rotating disks can not be compromised with the bumping technique, as well as restricted or registered key profiles because the correct key-blanks cannot be legally obtained without permission or proper registration with an accredited locksmith association.
