I have had my car about 3 hours and the alarm went off in the driveway untouched and now the remote will not lock or unlock the car. The alarm appears to arm itself without pressing the lock button but it doesn't go off when you open a door. The lights/taillights,etc. will come on when pressing "unlock" but the doors do not unlock. It's really putting a damper on my "new car experience." Any ideas other than back to the dealer?
