Anyone have any ideas on this? My factory installed car alarm has been having problems for about 6 months. At random times it goes off for no reason...the car is locked and it goes off...the doors are unlocked and you open the door and the alarm goes off...in the middle of the night in thegarage the alarm goes off. I believe it is tied into the factory installed remote start. Now the alarm hasn't gone off in 2 days but the remote start now doesn't work. Anyone know of the answer to this mystery?
