I went out to my jeep and opened the passenger door and the alarm went off. Confused cause i thought i locked it and wondering why if I forgot to lock it would the alarm go off. I used the key fob and locked the jeep and went to open the passenger door again and sure enough it opened. So I went to the drivers door and tried to lock all doors through the witch on the door. Every door locked and unlocked with both the key fob and the switches but not the passenger door. Oddly enough even the switch on the passenger door locked all doors except the passenger door. What could be the problem here?
