Getting started
Drill, baby, drill
A little skill and a cordless drill opened most od the deadbolts we tested.
Many of the dead-bolt locks we tested don't provide the level of protection you might expect. A few well-placed kicks or a standard cordless drill was all it took to defeat most locks.
Those test results are especially unsettling because forcible entries, such as kick-ins, are the most common type of home break-ins. And 67 percent of respondents to our national survey count on dead-bolt locks to help keep their homes secure. But any dead-bolt lock is better than the common key-in-knob variety.
We spent weeks prying, hammering, picking, pummeling, and drilling locks, and few scored well. A handful proved far more susceptible than most.
Parts are often inadequate
All locks come with a strike plate that attaches to the door frame. But as we've reported in the past, far too many of those are flimsy. The kick-in resistance of most locks improved dramatically when we replaced the strike plates with a Mag High Security Box Strike, $10. You can buy it, or its equivalent, at home centers and online. But we think a lock should be secure without your having to buy another part.
Drills easily open most locks
With all except the two locks classified as high-security, even an ordinary cordless drill could drill out the cylinders in 2 minutes or less. Our tests on the Assa and Medeco, which have hardened cylinders across the product line, ruined the locks but denied access--so you'd have to replace the lock but not your home's contents.
New technologies and old problems
One tested model opens by fingerprint, passcode, or key. But while it claims "maximum protection for yourself and your loved ones," it was among the easiest to defeat. We found keypad-operated door locks convenient. Such models can be rekeyed for temporary access to guests and contractors and then rekeyed again, when access is no longer needed, without having to change the lock or call a locksmith. Yet all of those locks succumbed too easily to our prying/wrenching test.
