My father's had this car since 1998, and it has never happened until about a month ago. Now it happens maybe a couple times a week at random times.
To my understanding, the factory alarm is only supposed to go off if the door is opened from the inside when locked, and it used to be like that. Now, it goes off when there's nobody even near the car at 3 am, at 10 pm outside a restaurant, at 5 pm in our driveway. I'm positive that nobody's tampering with the locks. Is it possible that the wiring is messed up?
Thanks
