One car key left? Make a spare while you have it.
A working spare gives you a backup and makes sharing the car easier. Arrange it before the only key goes missing or stops working.
- A backup for a lost or damaged key
- A key for another driver
- A planned visit while the car is accessible

Why a second key is useful
Keep a working spare in a secure place separate from your everyday key and the vehicle. If the main key is lost or damaged, you still have a way to use the car. A second key also avoids passing one key between authorized drivers.
A spare and an all-keys-lost job can differ
Tell us whether your current key starts the vehicle, unlocks it and operates the remote buttons. Cutting and programming requirements depend on the vehicle and key type. Some manufacturer self-programming procedures require existing working keys; the Ford procedure linked below requires two programmed remotes for that vehicle. We check the service for your own year and model before booking.
What to have ready
- The year, make and model.
- Your working key or fob, including any faults.
- The vehicle location and whether you want mobile or shop service.
- Proof of ownership or authorization, as requested when arranging the job.
Ask whether the vehicle must be present and what the quote includes. If you bought a key online, send its details first; appearance alone does not establish compatibility.
Check the spare before relying on it
After service, check the starting, door-lock and remote functions that apply to your vehicle. Keep the spare somewhere you can reach if the main key is unavailable. If every key is already lost, call with the vehicle details and location so we can discuss replacement service.
