A Deadbolt Is Only as Strong as What It Locks Into

Longer strike-plate screws that reach the wall stud make a big difference.

A knob lock alone is easy to force. A deadbolt throws a solid steel bolt into the door frame, and it's the single most important lock on an exterior door. But many deadbolts are held by short screws in soft trim wood. One good kick splits the frame, no matter how good the lock is.

Our Deadbolt Installs Include

  • New deadbolt, or an upgrade of an existing one
  • Boring new holes in doors that don't have one
  • Reinforced strike plate
  • Long screws anchored into the stud
  • Bolt-alignment check so it throws fully
  • Keyed to match your other locks

Single or Double Cylinder?

A single-cylinder deadbolt has a thumb-turn inside. Double-cylinder models need a key on both sides, which is useful next to glass. They can slow an exit in a fire, though, so check local codes and think about who lives in the house. We'll walk you through the tradeoff.

Frequently Asked Questions

Can you add a deadbolt to a door that doesn't have one?

Yes. We bore the door and frame and install the deadbolt and strike.

What grade of deadbolt should I get?

For exterior doors, we recommend a solid residential or commercial-grade deadbolt. We'll show you options on site.
