Parked up at an Aire in Bourg en Bresse last night. We went for a walk and tried to switch on the Alarm with one of the fobs, it wouldn't work so got the other one out and switched it on. When we got back neither of the fobs, were working. I had visions of having to let the alarm go off and try and find wires under the bonnet that goes to the alarm. I took both apart and fiddled with them and eventually got one to work. I was thinking I don't ever remember changing the batteries in either of them and if I have it would only have been once, both over 20 years old. Got the batteries this morning thank goodness
