Deadbolt Lock Installation

Deadbolts That Actually Hold the Door

Most break-ins succeed through a weak strike plate, not a picked lock. We fit Grade-1 deadbolts with 3-inch screws and reinforced boxes — then rekey everything to one key.

Deadbolt Questions

Single cylinder (key outside, thumb-turn inside) suits most homes and is safest for fast exit. Double cylinder needs a key both sides — better for doors with nearby glass, but check local fire codes first.

Usually yes. If the brands share a keyway we'll pin the new deadbolt to your current key. If not, we rekey everything to one fresh key at no extra labor charge.

About 45–60 minutes per door including reinforcement and testing. Whole-home jobs of 3–4 doors typically finish in one morning visit.
