¿How to use a Bump Key?

Bump keys should always have a rubber band around them to protect the lock from the hammer


These keys are inserted into a lock the same way as a traditional key. Once the key is in the lock, the user applies pressure to the back of the key while simultaneously striking the front of the key with an object (usually a hammer). The impact causes the pins in the lock to become misaligned, which allows the lock to be opened.

There are many techniques to pick a lock, and lock bumping is one of the fastest; however, it doesn’t mean that it will work every time; this is just one of many methods you can use to open locks at your home or office.

They can be made from any key by filing down the teeth so that they are all the same size. This makes it possible to open any lock that uses the same type of pin configuration as the one on the bump key (i.e., wafer tumbler, sidebar, disc tumbler, etc.).
