Deadbolt installation & replacement
A properly installed deadbolt is one of the best upgrades you can make to any door. We install, replace and upgrade deadbolts for homes, apartments and businesses.
- Single and double cylinder
- Keyed alike with your other locks
- High-security deadbolts available
A deadbolt is only as strong as its install
We make sure the bolt fully extends into a solid strike, use long screws into the frame where the door allows, and check that the door is aligned so the bolt doesn't bind.
Whether you're adding a deadbolt to a door that doesn't have one, replacing a worn one, or upgrading to a high-security model, we'll fit it right.

Deadbolts FAQ

Single or double cylinder?
Single cylinder has a thumb turn inside and is the most common. Double cylinder needs a key on both sides and is sometimes used near glass. Check local fire and building rules for your door; we'll advise.
Can you add a deadbolt to my apartment door?
Usually, yes. Check your lease and building rules first, and we'll handle the install.
My deadbolt is hard to turn. Can you fix it?
Often that's alignment, not the lock. We'll adjust the strike or door before recommending a replacement.
