Spare Key Programming

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.
  1. Insert the unprogrammed PATS key into the ignition and turn the key from the OFF position to the RUN position.
  2. From the scan tool, enter TOOLBOX. Select BODY - SECURITY - PATS Functions and follow the Integrated Diagnostic System (IDS) onscreen instructions to ENTER SECURITY ACCESS.
  3. From the scan tool menu select "Program additional ignition key" and follow the IDS on-screen instructions.
  4. The engine should now start with the new PATS key.
