So... It seems all I ever post here is problems and its getting a little old. So the new one is my car alarm keeps going off. It's really quite so from inside I don't even hear it unless the windows are open. The only way I know is either someone telling me its going off or when I get in the car it says alarm triggered. It seems to do it for no apparent reason. I thought I remembered reading a thread a while back that talked about some sort of back up battery that goes bad? I can't seem to find the thread now though. Any help would be much appreciated as I've completely stopped using the alarm. I lock the doors with the key blade to avoid further false alarms. It's an 05 s40 awd 6spd. Thanks in advance!
