i'm having problems with the door locks the interior lights and the windows. the remote will not even start the car.i bought the jeep grand Cherokee one year ago and never used it. tried it one time and all that happened was the lights flashed and that's it.now the darn jeep is going electrically crazy.every blue moon the lights and locks will work like they should but not oten. does this sound like a remote starter related issue.MODEL#500.
