Burglars Are Bumping
September 23, 2011
Okay America, listen up. Have you heard of lock-bumping? If not, it’s important you pay attention.
Lock-bumping first gained notoriety in 1928 when the bump-key was patented. This tool was made for locksmiths as a way for them to quickly disassemble a lock. Over the years the technique has attracted more attention and gained popularity amongst burglars. With a little practice and the right tools almost anyone can do this.
A bump-key is most effective in a pin-tumbler lock, which is one of the most popular locks sold in America. This kind of lock is composed of multiple spring loaded stacks called pin stacks. These pin stakes have two parts that are vertically stacked atop one another. To bump a lock you must insert the correct kind of key (a bump key) and tap against its end. The force will cause the pin stacks to jump for a split second. If the person on the other end simultaneously tries turning the key while hitting it, they will be able to unlock the door.
Thankfully, bump keys can only be sold to locksmiths. However, burglars can easy find a bump key online or make one themselves by grinding down a regular key. What proves more unfortunate is high-quality locks are more vulnerable to being bumped because their steel is less likely to damage and jam.
The good news is there are ways to prevent this security problem. To start, you can change your locks. Any lock that does not use top pins or contain springs is bump-proof. Mechanical locks that require a combination are great solutions. Another precaution you can take is wireless security. A motivated thief will find alternative ways to gain access to your home regardless of a “bump-proof” door. Your next best line of defense is having a home security system to stop them in their tracks. Seen as one of the most effective ways to prevent break-ins, a security system is a wise choice when it comes to protecting your home and family.
