while I was away for two months the cars battery and the key fob battery went dead at the same time. the car has factory fitted isolation unit. having fitted new batteries and followed the hand book instructions , the key fob will lock and open the car and the key will start the engine, but I can not stop the alarm ringing without dissconecting the car battery.
Anyone any suggestions ?
ps the car is like new 20,000 miles no former issues just routine service
