Hi I have a 1994 discovery it came with keys and a demobilize system. The demobilize system is activated with a small device with something like a magnet on the end of it and when you touch it on the device fitted in the steering column it then is activated. The problem I have is that I have lost the small device which activates the demobilize system. Would any one know is this a rover part or would any one know how I can bypass it to get my discovery started.
