Car Key Duplication in San Diego

Only one car key? That is the best time to get a spare. Key One Locksmith copies car keys at your location anywhere in San Diego County, including chip keys that must be programmed to start the engine.

Why a Hardware Store Copy May Not Start Your Car

Many cars built since the late 1990s have a chip in the key. A plain cut copy may open the door but will not start the engine. We cut and program the chip so your spare works like the original.

How It Works

1. Call us with your year, make and model.
2. We come to you with the right key blank.
3. We cut the spare and program the chip if your car needs it.
4. We test the spare in the door and the ignition.
