Using Diagnostic Equipment

NOTE:
^ This procedure is used when a customer needs to have an additional key programmed into the vehicle without erasing stored key codes, but does not have two programmed keys available. This procedure is also useful when attempting to determine if an ignition key is defective.
^ Before programming, the new key must have the correct mechanical cut for the ignition lock.
^ If 8 keys are already programmed, this procedure will not allow any further ignition keys to be programmed without erasing all stored key codes first. The number of keys programmed into the system can be determined using the PID NUMKEYS.

1. Turn the ignition switch from position 0 to position III using the new, unprogrammed ignition key.

3. From the NGS or SBDS menu Select: IGNITION KEY CODE PROGRAM.
4. Turn the ignition switch in position 0 and disconnect the NGS or SBDS.
5. Attempt to start the engine with the new ignition key. The vehicle engine should start and run normally.
