General Description
Key Coding ConstructionS6RW0D9601001
Key Usage and Identification

Key identification is obtained from five character key code stamped on key code tag. Using this key code, key code
cutting combination can be determined from a code list (available to owners of key cutting equipment from suppliers).
Rear End Door Opener System DescriptionS6RW0D9601002
Rear end door opener system consists of rear end door opener switch (1), rear end door opener relay (in BCM), rear
end door lock assembly (2) and BCM (3).
Rear end door opener system is activated by pushing rear end door opener switch after all doors are unlocked by
manual door switch, key cylinder switch, keyless entry transmitter or request switch (5) (if equipped).
When rear end door opener switch pushed rear end door opener relay is ON. Then, BCM releases latch of rear end
