Key Identification and Usage

The lock cylinder keyway is designed so that other model keys will not enter a current model lock cylinder. A single key is used for all locks on the vehicle.

The key identification is obtained from the five-character key code on the barcode tag. The code list, available to owners of key cutting equipment from equipment suppliers, determines the lock combinations from the code numbers.
