How to resynchronize the door locks?
After manually locking or unlocking the system, the door locks may become unsynchronized. To synchronize the locks, close all doors, trunk lid and tailgate. Lock the passenger door by turning the key clockwise into the emergency locking position (approximately 110 degrees from position O). Unlock the driver’s door. If any of the locks do not operate, repeat the locking procedure until the locking system is synchronized. This might happen if a door which is not completely closed is locked, or a door handle is lifted before the interior lock button is raised.
