Motion sensor? That's odd! I think that the motion sensor on the alarm system is pretty sensitive, though. I've locked my doors with the windows open (out of habit, since the lock button is right there!) One of my friends reached inside through the window for his sunglasses, without touching the car at all, and set the alarm off. I couldn't believe it, so of course I had to try it for myself. Based on what I've read, I think it has a "Ultrasonic Interior Motion Sensor", so maybe something's faking that out? |
