Types of deadbolt
- Single cylinder: key outside, thumb turn inside. The most common choice.
- Double cylinder: key on both sides. Check local fire and building codes before choosing one.
- Keypad and smart: code or phone access, usually with a key backup.
- High-security: pick- and drill-resistant cylinders with restricted keys.
Installation matters
The bolt should fully extend into a solid strike. We check the alignment, fit a reinforced strike plate where needed and use screws long enough to reach the framing behind the door jamb.
Signs your deadbolt needs attention
- The bolt does not throw fully or catches on the strike
- The key is hard to turn
- The cylinder spins or feels loose
Frequently asked questions
Can you add a deadbolt to a door that does not have one?
Usually, yes. We drill and prepare the door and frame, then fit the deadbolt and strike.
Can a new deadbolt match my door handle key?
Often, if both use the same keyway. Ask us when you call.
Are double-cylinder deadbolts allowed?
Rules vary. Check with your local building or fire authority, especially for doors that are a main exit.
