[devonsteve]

we have a new to us 2011 Adria Coral 670 SLT on the Habitation door lock it shows a lock and unlock symbol the unlock side works fine but when I turn the key to lock he has door I have to turn the key back to the centre to remove the key this intern unlocks the door I can lock it but only by using the cab electronic push button I don't want to keep unlocking / locking the driver and passengers doors every time we go in or out any ideas please
