The only way I can get the passenger door to lock is with the key fob. There is a switch on the drivers door in back of the power window switch. It has a red lighted dot on one side and door logo with key on the other. I didn't see anything about it in the owners manual, but it seems to lock and unlock other doors, but not the passenger or drivers door. The only way I can lock the drivers door from the outside is with the fob or key. If I try to lock with the inside switch, then close the door, in is unlocked. Any help appreciated.
