A tumbler lock made of pins is composed of a series of pin stacks. The instant the correct key is inserted into the lock, all of the key pins and driver pins line up which in turn allows for the cylinder to move. Whenever no key or the wrong key is put within the lock, pin misalignment hinders the cylinder from turning. So you figure your lock is extremely secure.
Whenever the lock bumping device is used, a key is inserted in the keyway and bumping this key into the keyway forces the key to be pressed deeper into the keyway.
The key employed for key bumping is specifically created with teeth that transmit a pressure to all of the base pins in the lock. If perhaps a moderate pressure is continuously applied to the bump key in the course of the impact of bumping, the cylinder will turn and the lock can be opened up.
Lock bumping usually takes mere seconds to open up a lock. The lock is not broken whatsoever, so the owner would certainly in no way find out. When a lock bumping tool is employed to break into a residence or enterprise there would be no indicators of forced entry or destruction, which can make house or business insurance tough to claim.
Electronic locks that have got backup key insertion are vulnerable to lock bumping. Presently there are several high security locks that can never be bumped
Normal locks may be prone to bumping unless of course they are constructed with certain countermeasures. Locks made of hard steel are susceptible to lock bumping mainly because they are less prone to destruction during the bumping method that might cause a less costly lock to jam.
Locks which usually are manufactured with security pins even if they are combined with a typical tumbler system make lock bumping more difficult but clearly not impossible. Locks that are produced with trap pins that engage when a pin is not reinforced will jam a lock's cylinder making lock bumping complicated if not impossible.
Shallow drilling in which one or more of the pin stacks is drilled shallower than other is another countermeasure for lock bumping. Making an attempt to bump a lock that has shallow drilled pin stacks will show to be impracticable simply because the bump key will be incapable to bump the shallow drilled pins due to the fact they are too high for the bump key to work.
There are a range of bump resistant locks offered which cannot be easily opened because of the lock bumping method.
