A single key is used for all of the locks on the vehicle. The key identification is obtained from the four-character key code located on the key tag. The four character key code should be recorded by the owner and the dealer. The mechanical key code can be determined through the use of a code cross-reference list which is available to owners of key cutting equipment from the equipment suppliers.
After the mechanical key code has been determined from the code list , perform the following steps:
The lock cylinder keyway is designed so that other model keys will not enter a current model lock cylinder. New lock cylinders are available from the service parts warehouses without tumblers and springs. The tumblers and springs are also available and must be assembled into the lock cylinder according to the mechanical key code.
All lock tumblers are shaped alike with the exception of the notched position on one side. As the key is inserted into the lock cylinder, the tumblers are lowered to the correct height so that notches on each tumbler are at the same level. When the notches on all six tumblers line up, two small springs push the side bar into the notches, allowing the cylinder to turn in the cylinder bore. Five types of tumblers are used in making the lock combinations. Each tumbler is coded and stamped with a number between 1 and 5.
