Most break-ins are committed by criminals who come right through the front door, according to Department of Justice statistics. Even if you're diligent about locking up, you need a good deadbolt to thwart thieves. 'The bolt portion of the lock, called the throw, isn't the part that fails to hold up in our tests,' says Dave Trezza, an engineer who runs. 'There are other design flaws that allow burglars to break through and gain entry.' Most locks use steel in the cylinder, which can be drilled open.

The best locks use hardened steel or brass, and some reinforce the cylinder with hidden steel plates. It's still possible to drill through a lock that has these built-in enhancements, but it can take so long that thieves give up and move on. The biggest design flaw Trezza sees relates to the strike plate, the metal piece that holds the throw in a doorjamb when the door is locked.
