Lock bumping involves using a key that was specially cut and known as a bump key. It can fit into most door locks and can manipulate the pins of almost any cylinder lock which is the most common lock used in residential properties.
When the bump key is inserted into the lock and then tapped or “bumped” with an object like a screwdriver it creates a momentary gap between the pins that allows the lock to be turned and opened without the correct key.
How do you prevent lock bumping?
To prevent lock bumping consider installing bump proof or high security lock like an electronic or biometric lock.
Reinforcing door frames and using a secondary deadbolt can also deter lock bumping because the process is very noisy and by having more than one lock means it will take longer and someone will surely notice.
