Hi everyone, I'm new to the site but hope someone can shed some light on this fault or point me in the right direction.
I have just purchased a 2007/57 C320CDi 7G that came with 2 keys. The seller advised me that only one key was working. The faulty key is the one that had been used since new until 2 weeks ago, the failure is as follows.
Key locks/unlocks the car, goes in the ignition, turn the key and the engine turns over but the car fails to start. It's almost as though the immobiliser is still activated. The spare key that I'm using now works perfectly but I dont want to wait until I have two faulty keys.
Any help would be appreciated.
I'm an Industrial Air Compressor Engineer based in Scotland, been doing it for over 20 years and if anyone needs any help feel free to ask and I'll do what I can.
