My 1994 UK Citroen ZX has developed problems with the alarm. When using the key fob to lock the car up the car locks itself and then straight away unlocks itself. There is often a flashing of idicators although the alarm itself it doesn't sound (I don't think it actually works).
Whilst I am not bothered about having a working alarm I do need to be able to lock the car. The car won't lock by using the key in the door either.
I have tried various combinations of starting the car with the alarm button depressed and trying to lock the car from inside but to no avail. Does anyone know what is causing this? I don't want to take the car to a dealer as it only cost me £75!
