KEY CODING
KEY USAGE AND IDENTIFICATION
Key is used for ignition and door lock cylinder. Keys are cut on both
edges to make them reversible.
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 cut-
ting equipment from suppliers).
If key codes are not available from records or tags, key code can
be obtained from the right hand door lock cylinder (if lock has not
been replaced). Lock cylinders supplied by the factory as service
parts are unmarked.
If original key is available, key code cutting combination can be de-
termined by laying key.
