Parked in carport as usual. Alarmed car as usual. Alarm went off for 30 sec. Unalarmed car and stood there looking at it. After 5 min car alarmed itself and then the alarm went off. Nobody touched it or the key. Thigh appended 4 times. I moved the car to the other side of the property and alarmed it. So far it has been quiet.
