High security locks like these can't be opened using the "lock bumping" technique.
By Meredith Harvie
The Internet is making an age-old break-in technique available to the public. It's called lock bumping and all it takes is a dummy key and a hammer to break-in a home. Internet sites have step by step instructions on how to lock bump your home.
There are ways to protect yourself.
"Have a high security lock something that uses more than just a conventional key," says locksmith Larry Bachman. These locks do cost more than a normal lock, but could save you money in the long run. Break-ins using the lock bumping technique are hard to file with insurance.
"It leaves no visible signs of entry," says Bachman.
The high security locks run at about $150 and are available through most locksmith stores.
