When I lock my doors I have a 4dr by the way but when I do I get out shut my driver door and hit the button on the keychain and every door locks except the driver door I have to lock it with the key.the button use to work on all 4 doors but now just 3 and 1 thing I hate is when all the doors are unlocked they lock by their selves when all the doors close except the drive door.whats causing this
