What Is Car Key Duplication?
Car key duplication means copying a key that already works. Your original key is the pattern: we cut a new blade to match it, and if your car uses a transponder chip or a smart key, we program the copy so the car recognizes it and starts. Because it starts from a working key, duplication is the quickest and simplest way to get a spare before you need one. If every key is lost or none of them works anymore, the job becomes a key replacement instead, and we handle that too. A spare kept at home or with another driver also means a lost key becomes an inconvenience, not a lockout.
What Our Car Key Duplication Includes
Standard key copies — Metal keys cut to match your original, for older vehicles without a chip
Chip key copies — Transponder keys copied and programmed so the spare starts your car
Push-to-start key copies — An extra smart key added to your vehicle for keyless entry and ignition
Spares for every driver — One copy for each person who uses the car, so no one shares a single key
On-site duplication — Your spare is cut and programmed right where the car is parked
