How to Stop Bump Keys

A regular lock is no match for a bump key.

Bump keys are locksmiths' tools which can open most standard door locks. When used legitimately, they can help locked-out owners get into their own homes. But burglars can also use them to enter a locked house and rob it. This puts not only your possessions at risk, but your family as well. This is why it's often a good idea to take preventative steps to prevent bump keys from working. There are several options.

Things You'll Need

• Lock (electronic or bump key resistant)
• Spray lubricant

Instructions

1. Purchase a lock specifically designed to foil bump keys. Medeco and Abloy are two companies which specialize in this.

2. Apply a spray lubricant to the lock's interior. This isn't as effective as a specialized lock, but it's cheaper.

3. Install a chain lock. Since chains don't have a keyhole outside, they can't be opened with a bump key. This will help protect you when you're in the house, but, since you can't lock it when you leave, your house is still vulnerable when you're away.

4. Purchase an electric keypad. Since this doesn't require a physical key at all, a bump key will be useless.
