Door Lock Cylinder Coding

WARNING: This page is about a different car, the 2009 Pontiac Torrent and 2009 Chevrolet Equinox. However, it is still accessible from the selected car via links, so may be relevant.

Handing is determined by color of pawl. Orange is left hand and green is right hand.

IMPORTANT: The door lock cylinder reads key cut position 4 through 9.

Insert the appropriate tumbler (5) according to the key code into the corresponding tumbler ward.
The tumblers will not immediately seat into position because the sidebar has been pre-assembled. The tumblers will have to be pushed past the sidebar with a small flat screwdriver or pocket knife.
The tumbler springs (4) should then be inserted into the spring wells in the cylinder (3) where they will sit on top of the tumblers.
