If it is desired to program additional key(s), refer to Key Programming Using Two Programmed Keys See: Accessories and Optional
Equipment/Antitheft and Alarm Systems/Testing and Inspection/Programming and Relearning/Anti-Theft - Passive Anti-Theft System
(PATS)/Key Programming Using Two Programmed Keys for each additional key that needs to be programmed. The IC PID SPAREKEY must be
set to ENABLE.

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 2 programmed keys available. This procedure is also useful when attempting to determine if an ignition key is defective, as a new key can
be programmed without erasing keys or without having 2 programmed keys available.
NOTE: Before programming, the new key must have the correct mechanical cut for the ignition lock cylinder.
NOTE: If 8 keys are already programmed, this procedure does not allow any more ignition keys to be programmed. The number of keys that are
programmed into the Passive Anti-Theft System (PATS) can be determined by viewing the Instrument Cluster (IC) PID N_KEYCODE.
1. Turn the new key to be programmed from the OFF position to the ON position.
2. From the scan tool, enter TOOLBOX. Select: BODY - SECURITY - PATS Functions and follow the Integrated Diagnostic System (IDS)
on-screen instructions to ENTER SECURITY ACCESS. For additional information, refer to Anti-Theft Security Access See: Accessories and
Optional Equipment/Antitheft and Alarm Systems/Testing and Inspection/Component Tests and General Diagnostics.
3. NOTE: Make sure the selection made is "Program additional ignition key". If the "Ignition Key Code Erase" selection is made, all of the keys will
be erased from the system.
From the scan tool menu select: "Program additional ignition key".
4. NOTE: The 20-second delay is to allow sufficient time for the module to exit its diagnostic mode.
Turn the key to the OFF position and disconnect the scan tool (wait 20 seconds).
5. Start the vehicle with the new PATS key. The vehicle will now start with the new PATS key and also with the original PATS keys. If it is an IKT
key, verify the RKE functions (if there are 4 or fewer IKT keys programmed).
