Sometimes when I lock the my Explorer either via the door button or via the OEM remote, when I come back to the car it is unlocked. I've also noticed that when I unlock just the drivers door (1 unlock press on OEM remote and sit with the door open after a minute or 2 the other doors unlock by themselves.
This is undesired behavior as unlocked doors are an open invitation for criminals to help themselves to property in my car that I want to stay locked.
