for each additional key (up to 8 keys, total) that needs to be programmed. The IC SPAREKEY PID must be enabled.
Spare Key Programming - Using Diagnostic Equipment
Spare Key Programming - Using Diagnostic Equipment
NOTE: This procedure is used when a customer needs to have an additional key programmed into the vehicle without erasing the 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 installed 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 Passive Anti-Theft System (PATS) keys to be programmed without
erasing all stored key codes first. The number of keys that are programmed into the PATS can be determined by viewing the Instrument Cluster (IC)
N_KEYCODE PID.
NOTE: When in the unlimited key mode, the N_KEYCODE PID always reads 2, no matter how many keys are programmed to the vehicle (after the
first 2 keys have been programmed).
1. Insert the new, unprogrammed PATS key into the ignition lock cylinder and turn the key from the OFF position to the ON position.
2. From the scan tool, enter TOOLBOX. Select BODY-SECURITY-PATS Functions and follow the 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" (Program additional ignition key). If the "ERASE" (Ignition Key Code Erase) selection is
made, all of the keys will be erased from the system, and the vehicle will not start until a minimum of 2 keys are programmed into the IC.
From the scan tool menu select: "Program additional ignition key" and follow the on-screen instructions.
4. Turn the key to the OFF position and disconnect the scan tool.
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.
Passive Anti-Theft System (PATS) Parameter Reset
Passive Anti-Theft System (PATS) Parameter Reset
NOTE: If the vehicle is not equipped with Passive Anti-Theft System (PATS) or is equipped with PATS, and the Instrument Cluster (IC) or the PCM is
being replaced (or both), the parameters must be reset in both modules or the vehicle experiences a PATS no-start. PATS vehicles and non-PATS
vehicles have parameters in the IC and the PCM and they must be reset whenever either (or both) module(s) is (are) replaced.
NOTE: When using the Integrated Diagnostic System (IDS), the IC and the PCM parameters are reset at the same time.
NOTE: Once security access has been granted, multiple security access commands should be executed (if necessary) prior to exiting the command
