Lock Cylinder Tumblers
WARNING: This page is about a different car, the 2003 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
Each of the 4 depths on the key has corresponding tumblers, sometimes referred to as plates or wafers. The numbers are stamped on the tumblers for identification. Door and liftgate tumblers and ignition tumblers represent 3 different series. There are also three different compression springs. It is essential that the correct components be used in the tumbling of locks. The compression springs are inserted into the springs wells, and then the correct tumblers are inserted into the tumbler wards for the door and liftgate. The ignition is tumbled differently. Insert the correct tumbler into the tumbler wards then insert the tumbler springs on top of the tumblers.
