The problem is one of the door switches, hood switch or trunk switch is setting the alarm off while the vehicle is parked. More than likely it is one of the door switches. Try this. Get a can of spray penetrating oil like WD-40 or PB-Blaster into each door latch and open and close each door up to 20 times and then let the vehicle sit. Also, check the hood switch, which should be mounted on the radiator support and also make sure the trunk is fully closed.
