Unlike a spring latch, a deadbolt can't be pushed back with a card or shim once it's thrown. But a deadbolt is only as strong as its installation: a short bolt, a weak strike plate or short screws into a soft door frame can let a door be kicked in. We fit the lock and reinforce the parts around it.
Deadbolt options
Types
- Single cylinder (key outside, thumb turn inside)
- Double cylinder (key on both sides)
- Keypad and smart deadbolts
- High-security deadbolts with restricted keys
Installation extras
- Reinforced strike plates
- Longer frame screws
- Adjusting the door so the bolt fully extends
- Keying to match your other locks
A note on double cylinder deadbolts
Double cylinder deadbolts need a key to open from inside, which can slow an exit in an emergency. Local building and fire codes may restrict them on some doors. We'll talk through the trade-offs before installing one.

Frequently asked questions
My deadbolt is hard to lock. Does it need replacing?
Often not. A sagging door or misaligned strike is the usual cause. Adjusting the strike can fix it.
Can you add a deadbolt to a door that doesn't have one?
Yes. We bore the door and frame and fit the deadbolt and strike.
