What to look for in a front-door deadbolt so it actually holds up to a forced entry.
Deadbolts are graded 1, 2, or 3 by ANSI, with Grade 1 the strongest. For an exterior door, a Grade 1 or Grade 2 single-cylinder deadbolt offers a good balance of security and value.
A one-inch bolt throw and a strike plate anchored with long screws into the door framing matter as much as the lock itself. Even a strong deadbolt is weak if the strike pulls loose.
