Keyless Entry Transmitter: Testing and Inspection
Spare Key Programming
SPARE KEY PROGRAMMING
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, as a new key
can be installed without erasing keys or without having 2 programmed keys available.
Before programming, the new key must have the correct mechanical cut for the ignition lock.
If eight 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 the OFF position to the RUN position using the new, unprogrammed ignition key.
2. Using the diagnostic tool service function card, select PCM from the menu. Follow the SECURITY ACCESS PROCEDURE to obtain security
access. See SECURITY ACCESS - PROCEDURE.
3. From the diagnostic tool menu, select: IGNITION KEY CODE PROGRAM.
4. Turn the ignition switch to the OFF position and disconnect the diagnostic tool.
5. Attempt to start the engine with the new ignition key. The vehicle engine should start and run normally.
