Types of Car Keys We Replace in London
Remote Car Keys
Remote keys allow you to lock and unlock the vehicle using buttons on the key. If the remote has stopped working or the key shell is damaged, we can check whether it needs repair, reprogramming, or full replacement.
Smart Keys and Proximity Fobs
Smart keys and proximity fobs are common on newer vehicles. These allow keyless entry and push-button start. We offer smart car keys London support for many vehicle makes and models.
Transponder Keys
A transponder key contains a chip that communicates with your car’s immobiliser. If the chip fails or the key is lost, the car may not start. Our transponder key programming London service can help restore access and starting function.
Replacement Key Fobs
If your key fob is damaged, missing, or no longer responding, we can advise whether it can be repaired or needs replacing. You can also view our replacement key fob London service.
