It started "unlocking" while I was driving. Now, it won't stay locked while parked either. While driving, all locks will pop up. I will relock it and about 30 seconds later, they unlock again. Now, When I get out of the car and lock it, they immediately unlock. I will use the "fob" to lock it, I will turn around to walk away and they will unlock again. I can't keep it locked... WHY???????
