Car alarm/HORN keeps going off when i open the door - any door, or if i lock adn unlock the car with the remote. then stops by itself.
any idea? ive had the driver door replaced, (2 weeks ago) but only started doing this yesterday.
ive tried pressing buttons on teh remote - and all but nothign works! it just goes off in about 20sec.

Another thing it also it happens even if i pop the hood. Sometimes im may open the door and it wont go off but then if i open it again it will...
