The History of Lock Bumping

If you just heard about lock bumping and are searching for more information about it then you can visit this public site Lock Bumping. They have a wealth of information about lock bumping. There are a few lock bumping videos that show how to use a lock bumping key on homes out there that will scare the pants off you. I have even seen some videos of how to lock bump.

Lock bumping originated in Europe. It seems that in late 70's some locksmiths figured out how to compromise our conventional door locks. This was all well and good because the rest of the world knew nothing of this. But with the advent of internet and it was only a matter of time before this secret lock bumping technique got out and into the wrong hands. All you have to do is type in bump keys and you will get a bunch of companies selling the keys.

There are a few lock bumping solutions out there. Security experts suggest gated communities with cameras and neighbor watches light up your doors, get a dog or just put better high security locks on your doors. The high security locks cost around 150 each but it is well worth the piece of mind if you are really frightened by lock bumping and the though of someone have a key to your doors.

I personally had to try lock bumping to see if it works. To my amazement it took me only 30 minutes or so to figure it out. I was truly amazed when the lock actually opened from this lock bumping technique.

Counter Measures - Lock Bumping

High-quality locks may be more vulnerable to lock bumping unless they employ specific countermeasures. More precise manufacturing tolerances within the cylinder make bumping harder for people to enter the front door of  houses such as those in san clemente because the mechanical tolerances of the lock are smaller, which means there is less loss of force in other directions and mostly pins move more freely and smoothly. Locks made of hardened steel are more vulnerable because they are less prone to damage during the bumping process that might cause a cheaper lock to jam.

Locks having security pins (e.g. spool or mushroom pins)—even when combined with a regular tumbler mechanism—generally make bumping somewhat more difficult but not impossible.

Because a bump key must only have the same blank profile as the lock it is made to open, restricted or registered key profiles are not any safer from bumping. While the correct key blanks cannot be obtained legally without permission or registration with relevant locksmith associations, regular keys can be filed down to act as bumpkeys.

Locks that have trap pins that engage when a pin does not support them will jam a lock's cylinder. Another countermeasure is shallow drilling, in which one or more of the pin stacks is drilled slightly shallower than the others. If an attempt were made on a lock that has shallow drilled pin stacks, the bump key will be unable to bump the shallow drilled pins because they are too high for the bump key to engage.

Locks that only use programmable side bars and not top pins are bump proof. Bilock is an example of this technology. Many bump-resistant locks are available which can not be easily opened through the lock bumping method. Baldwin and Schlage are two brands that offer bump resistant locks

Electronic locks, magnetic locks, and locks using rotating disks, such as disc tumbler locks, are inherently invulnerable to this attack, since their mechanism does not contain springs. However, some electronic locks feature a key backup that is susceptible to lock bumping.
