All cars produced and sold in the UK since 1995 are legally required to be fitted with an immobiliser system.
These cars require a transponder key with an embedded electronic transponder chip to start the vehicle. When the key is turned in the ignition the code is read and the vehicle will only start if the correct code is received.
This system was introduced to reduce vehicle crime and prevent cars from being started without the correct key. A broken or lost transponder car key will result in the vehicle not starting upon turning the key in the ignition
Here at Cool Diagnostics, we provide a fully equipped car key cutting and programming service designed to provide you with a replacement or additional car key that’s programmed to work perfectly with 90% of vehicles on the road.
We take great care to find the best solution to your problem, meaning that we can solve your key programming trouble and have your car running smoothly again with minimal delay.
In some cases we are able to programme keys directly to immobiliser / ECU by sending us the required unit. Again please contact for more details.
We are also able to supply and programme Renault key cards
And also Ford vehicles with coded access
