NOTE: This procedure only works if two or more programmed ignition keys are available, and it is desired to program additional key(s). If two keys are not available, follow the procedure in Key Programming Using Diagnostic Equipment.

NOTE: PID SPARE_ KY must be enabled for this procedure to operate. If this PID is not enabled, refer to Anti-Theft Security Access . With diagnostic tool, select Spare Key Programming Switch: Enabled.

NOTE: If the programming procedure is successful, the new key(s) will start the vehicle and the THEFT indicator will illuminate for approximately three seconds.

NOTE: If the programming procedure is not successful, the new key(s) will not start the vehicle and the THEFT indicator will flash. If the programming procedure was not successful, repeat the Key Programming procedure from Step 1. If the failure repeats, refer to DIAGNOSIS AND TESTING in this article to review diagnostic trouble codes (DTCs) and carry out pinpoint tests as required.

NOTE: A maximum of eight ignition keys can be programmed to a passive anti-theft system (PATS) equipped vehicle. Use PID NUMKEYS to determine how many keys are programmed to the vehicle.

NOTE: If the steps are not performed as outlined, the programming procedure will end.

NOTE: Ignition keys must have correct mechanical key cut for the vehicle and must be a PATS encoded key.

Insert the first programmed ignition key into the ignition lock cylinder and turn the ignition switch from OFF to RUN (maintain the ignition switch in RUN for one second).
Turn the ignition switch to OFF and remove the first key from the ignition lock cylinder.
Within five seconds of turning the ignition switch to OFF, insert the second programmed ignition key into the ignition lock cylinder and turn the ignition switch from OFF to RUN (maintain the ignition switch in RUN for one second).
Turn the ignition switch to OFF and remove the second key from the ignition lock cylinder.
Within 10 seconds of turning the ignition lock cylinder to OFF, insert the unprogrammed ignition key (new key) into the ignition lock cylinder and turn the ignition switch from OFF to RUN (maintain the ignition switch in RUN for 1 second).
If it is desired to program additional acceptable PATS key(s), repeat the applicable key programming procedure from the beginning.
