Key Fob Replacement
A replacement fob has to match the vehicle’s frequency, chip and buttons, and it must be programmed before it works. We check compatibility for your year, make and model and explain the available options. Not every used or aftermarket fob can be programmed to every vehicle, so we confirm before proceeding.

Key Fob Programming
Programming pairs the remote and its transponder with the vehicle so the lock, unlock, trunk and start functions work. On many vehicles this requires diagnostic equipment and the existing keys present. We tell you what your vehicle needs before the appointment.

Fob Not Working After a Battery Change
First check the battery type and that it is fitted the right way up. If the remote still does not respond, or the car shows “Key not detected”, the fob may need to be re-synchronized, or there may be a fault with the key, an antenna or the vehicle electronics. We test the fob and the car to find which one it is.
-
Doors Not Locking With the Remote
When the doors will not lock or unlock from the fob, the cause can be a weak battery, a key that lost its programming, a door the car reads as open, a failed lock actuator or a central locking module fault. We diagnose central locking problems and repair the actual cause.
Proof of ownership and identification are required for key and security services. Availability depends on the vehicle and its equipment.
Common Questions
Do I need to go to the dealership to program a key fob?
No. We program key fobs for BMW, Mercedes-Benz, Audi, Volkswagen, Volvo, Toyota, Honda, Nissan, Ford, Chevrolet, GMC and other makes, depending on the vehicle and the fob.
Can you program a fob I bought online?
Sometimes. It must match your vehicle’s part number, frequency and chip, and some fobs cannot be reused once programmed to another car. Send us the details and we will check before you book.
Why does my car say “Key not detected”?
Common causes are a weak fob battery, interference, a fob that lost synchronization or a fault in the vehicle’s keyless system. On many cars you can start it by holding the key against a marked area while we diagnose the problem.
