Thanks Martin. Still not certain that its the immobiliser though. Presumably it will cut off the spark at the plugs? If I get in the car the red light on the radio, and to the right of the driver's binnacle are both extinguished. So I presume its not armed then? It only comes on if I sit in the car and operate the key on and off a few times in quick succession. That arms the car, as the alarm went off at one time. So, from the above, am I to presume that the immobiliser is working OK?
