Why Deadbolt Locks Are a Smart Choice for Home Security

What is a deadbolt?

A deadbolt is a lock with a solid bolt that's moved by a key or thumb turn, not by a spring. Because it isn't spring-loaded, it can't be pushed back with a card the way some knob latches can. It's usually fitted above the door handle.

Single or double cylinder

A single-cylinder deadbolt has a key outside and a thumb turn inside; it's the usual choice for homes. A double-cylinder deadbolt needs a key on both sides, which can help on doors next to glass but can slow an exit in an emergency. Check local building and fire rules before fitting one on a door you'd use to escape.

Grades

Deadbolts are often rated to ANSI/BHMA standards. Grade 1 is the most demanding, Grade 2 is common for good-quality residential locks and Grade 3 is basic. For a main entry door, Grade 1 or 2 is a sensible target.

The strike plate matters too

Many forced entries break the door frame rather than the lock. A reinforced strike plate fixed with long screws that reach the wall framing makes a big difference, and it's an inexpensive upgrade.

Smart deadbolts

Smart and keypad deadbolts let you give out codes instead of keys and see when the door is used. They need fresh batteries and a backup way in, so choose a model with a key override.
