Doors Will Not Unlock Using the Key Fob or Central Locking Button. One or more of the doors may not unlock when using the remote key outside the vehicle, or the central locking button inside the car. It is still possible, however, to unlock the door by using the key in the driver's door lock cylinder or by pulling the door handle on the inside of the car. Typically fault codes A6D4 and A6D5 are stored in the Junction Box Electronics (JBE). This is due to a blown fuse in the JBE caused by either: * An excessive amperage draw by one of the door lock actuators, which is commonly attributed to silicone contamination; or * An intermittent, but acceptable, amperage spike slightly above 15A, due to normal variation in the locking system.
