What is the most secure lock for a front door?
The most secure front-door setup is an ANSI/BHMA Grade 1 or 2 deadbolt with a full 1-inch bolt, a reinforced strike plate fastened with long screws into the wall framing, and a pick-resistant cylinder. Most break-ins use force, so the strike plate matters as much as the lock.

- A reinforced strike platewith long screws that reach the wall framing, not just the trim

Get my price rangeDo I need a Grade 1 lock at home?
Not always. Grade 2 suits most homes. Grade 1 is built for heavy use or higher-risk doors.
What’s a double-cylinder deadbolt?
It needs a key on both sides. It stops someone reaching through glass, but slows your exit in a fire. Check local code first.
Do I need a new door?
Rarely. A reinforced strike and frame often adds more strength than a new lock alone.
