The dangers of bump keys and how vulnerable your door locks and deadbolts are to lock bumping burglars and robbers.

Did you know that there is a serious flaw involving common door locks and deadbolts, and any burglar or robber, or even a child, can easily defeat the lock and break into a home?

The technique is called “lock bumping”, and most of today’s door locks and deadbolts can be quickly opened in this manner. All it takes is a specially filed down key known as a “bump key” and a hard item to tap against the key. Within seconds the robber will be inside the home that was previously thought to be safe and secure.

Lock bumping requires that use of a special bump key for a home’s front door or deadbolt. Many of the bump keys are universal and will work with a wide variety of front door and deadbolt locks. The bump key is then placed in the lock like an ordinary key and gently turned while the robber taps on the end of the bump key with a hard item. The tapping sends vibrations through the cylinder of the lock and jiggles loose the pins, allowing them to become correctly aligned in the cylinder and letting the lock open. The lock is then unlocked and the robber is now quickly and quietly inside of the house.
It’s quick, quiet, and very effective with most locks. The only sounds you might hear are a faint tapping sound during the lock bumping process followed by the opening of the door.

This is a real home security nightmare!

The best ways to protect against this method are to:

  • Use high quality, “bump proof” locks.
  • Use a sliding chain, sliding lock or other restraining device that can only be accessed from inside the home or room.
  • Invest in some type of noise-making alarm system.

The problem with lock bumping is that every door you previously thought was secure may now be quietly opened within seconds. Apart from using an expensive “bump proof” lock, the only other real way of defending against this trick is to have another way of physically securing your doors from the inside of your home. This could be anything from using vertical and other sliding locks only accessible from the inside, to using a security chain or security bar wedged between the doorknob and floor.

This leads most people to another question: “If you have to use a door besides a garage door to leave your home, how can you still protect yourself against lock bumping? What are you supposed to do if you can only protect yourself by using security devices only accessible from the interior of your home?”

The first step is to protect your exterior doors with “bump proof” locks. After that, focus on the burglar’s worst fear – exposure. Invest in a simple security system that will sound a few seconds after the door is opened. It doesn’t necessarily need to be monitored by the police or by an expensive security company, but it does need to make a lot of loud noise. Loud noise alerts everybody in the area that something is wrong, and once it sounds the burglar will have to get out of there as quickly as possible.
