What You Need to Know

Single-cylinder deadbolts (keyed on one side) will work fine for most situations. Double-cylinder deadbolts (keyed on two sides) are a good idea if you have a window near the deadbolt. For safety reasons, if you choose a double-cylinder deadbolt, make absolutely certain your family knows where the key is and leaves it there.

Calling a locksmith out for this how to install a deadbolt lock job will cost hundreds, but you can install a heavy-duty deadbolt yourself in less than an hour for a third of the price. That’s about average for a good deadbolt and a hole saw set. To cut through a steel door, make sure you get a “bimetal” hole saw set.

Use a Grade 1 deadbolt. Deadbolts have a grade rating of 3 to 1 (1 is the toughest). Most home centers carry Grade 1 deadbolts, such as Schlage’s Maximum Security Deadbolt, but you may have to hunt for them.

Install a strike box. A strike box strengthens the deadbolt by spreading the impact of a forced entry over a wider area and by helping tie the strike to the 2×4 frame, not just the jamb.

Use the rectangular faceplate. Most deadbolts allow you to choose between a rectangular faceplate and a round one that doesn’t require chiseling. Unless you have a steel door, don’t be tempted! The rectangular faceplate, recessed into the door, makes a stronger setup.
