We have a 2000 S80 with a new issue. The other day the door locks stopped working. When you put the key in the drivers door to unlock the car this also does nothing. We had to unlock the trunk using the key and climb through the car to get the doors open. We also had to manually unlock the gas tank from the trunk. Once in the car we tried the lock button on the drivers and passengers door which did nothing. We manually pulled up the lock on the door when unlocked the door but only that door. Can someone please point me in the direction of the issue
