Lock Installation and Repair in San Diego

A lock that sticks, a deadbolt that will not line up, or a door that only has a knob latch. Key One Locksmith installs and repairs locks for homes and businesses across San Diego County, and we set up the new keys or codes with you before we leave.

What We Install and Repair

• Deadbolts. New or upgraded deadbolts with a strike plate screwed into the frame stud.
• Smart and keypad locks. Installed on your existing door and set up with your codes or app.
• High-security locks. Cylinders built to resist picking and bumping, with keys that cannot be copied at a hardware store.
• Handle sets and levers. Front door handle sets, interior levers and storeroom locks.
• Lock removal. Old, damaged or unwanted locks taken out cleanly.
• Repairs. Sticking bolts, loose handles, misaligned strikes and worn cylinders.

How It Works

1. Tell us the door and what you want: repair, upgrade or a new lock.
2. We give you the price before we start.
3. We install or repair, align the bolt and test it from both sides.
4. We hand over the keys, or set up codes with you.

Only need new keys, not new locks? Rekeying is often enough.
