Lock Bumping

[arppt01]

By restricted key do you mean a key whose dice is unique and not known by anyone other than the manufacturer?

He probably also means a key that you have to produce i.d. and sign to get a copy made.

I think that is one reason why you should by expensive locks. And if you are in your home, have chains installed as well. Don't rely purely on door knob locks.

basicly what u said

LockBumping has been a locksmiths tool for over 50 years - as with all locksmith tools they are designed to aid the entry and bypass a/the locks built in security. There are anti-bump products available to purchase that are quite reasonably priced personally i think LOCK SNAPPING will be a bigger threat to your homes security -
The principle of lock snapping is an easy one. Apply enough force to the cylinder and it will break across it's weakest point. This is usually accomplished using a pair of mole grips, or a claw hammer, basically anything that can be used the physically grab the cylinder. Obviously Lock snapping leaves much more evidence of a break in than lock bumping, but ultimately the result is the same, an intruder is able to enter your home. In terms of time scale Lock Snapping is equally as quick as Bumping, taking only a few seconds to snap a cylinder.
As lock snapping targets only the cylinder, all the security measures you have on your door such as roller keeps, shoot-bolts, anti lift bars and dead-bolts are rendered ineffective because once the cylinder has been removed the locking mechanism can be operated using a small rod of metal or a screw driver.

It is a scary theory...but like 'locksmith' stated, they must have a key that fits your particular lock first. The simplest thing to do would be to have a couple of locks installed on your door so even if they can crack one, they might not be able to crack the other.

On the other hand, most lockmiths will sell anti-pick and anti-drill locks which are designed to reduce this risk.

Hope that helps!
