How to Use a Bump Key & How to Create a Bump Key
Many people believe that simply keeping the door locked prevents theft. The truth is, for anyone who has taken the time to practice using a crash key, a door lock is little more than a minor inconvenience. The most common door locks in use today are bullet locks, while touch keys are specially designed keys that can be opened fairly easily with a little practice.
What are Bump Keys?
Most people think that a locked door provides them with security, but for anyone who knows how to use a crash key, a lock is a minor inconvenience.
A bump key is a key cut into a special design that can be used to pick a pin lock. Bullet locks are among the most popular locks in the world, and include exterior door entry locks used in homes. The process of using a collision key to enter is called "bumping," and it can be very effective.
All cuts in the bump key are machined to maximum depth, so any key blank can be made into a bump key. Bump bonds are manufacturer specific. A Kwikset lock requires a collision key made from a Kwikset key. The same goes for other lock brands. Therefore, the set of bump keys will include one from each major lock manufacturer.
How do I use bump keys
Learning how to use collision keys isn't difficult, but taking the time to understand how to use them properly will increase your chances of success.
Push the bump key into the lock like a normal key.
Once inserted, slowly pull it back until you feel it click twice.
Using a blunt object, hit the bump key with a little force while applying slight pressure to turn the key in the direction you need to open it.
The teeth of the key give a slight shock to the lower pins, which then transmit this energy to the upper pins, causing them to rise above the cylinder and shear line. The separation of the top pin from the bottom pin is brief, but the lock can easily turn.
How to create a bump key to open any door
If you are cutting a collision key from a key blank, you can do so using the same tools as your spare key. However, you may find it difficult to keep a straight line. This will result in a waste of the perfect key blank. Instead, it is best to use a key cutter for cutting.

The process here is actually quite simple.
Place your key into the cutter and cut the key to the lowest possible setting for that manufacturer. Clean it like you would any other key, and you have a perfectly usable bump key.
