Using Two Programmed Keys

KEY PROGRAMMING USING TWO PROGRAMMED KEYS

NOTE:
- This procedure only works if 2 or more programmed ignition keys are available and it is desired to program additional key(s). If 2 keys are not available, follow the procedure in Key Programming Using Diagnostic Equipment.
- PID SPARE_KY must be enabled for this procedure to operate. If this PID is not enabled, follow the security access procedure above and select Spare Key Programming Switch: Enabled.
- If the programming procedure is successful, the new key(s) start the vehicle and the anti-theft indicator proves out for approximately 3 seconds.
- If the programming procedure is not successful, the new key(s) do not start the vehicle and the anti-theft indicator flashes. If the programming procedure is not successful, leave the ignition switch in the RUN position for at least 30 seconds, and repeat the key programming procedure from Step 1. If the failure repeats, refer to Diagnosis and Testing to review DTCs and carry out pinpoint tests as required.
- A maximum of 8 ignition keys can be programmed in normal mode to a passive anti-theft system (PATS) equipped vehicle. If more are required, refer to Spare Key Programming. Spare Key Programming
- If the steps are not carried out as described, the programming procedure will end.
- Ignition keys must be the correct PATS encoded key type.
- If the vehicle is in unlimited key mode, this spare programming procedure still functions. Any 2 keys that can start the vehicle may be used to program an additional unlimited key.

1. 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 3 seconds, but no more than 10 seconds.
2. Turn the ignition switch to OFF and remove the first coded key from the ignition lock cylinder.
3. Within 10 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 3 seconds, but no more than 10 seconds.
4. Turn the ignition switch to OFF and remove the second coded key from the ignition lock cylinder.
5. Within 20 seconds of turning the ignition lock cylinder to OFF, insert the unprogrammed ignition key (new key/valet key) into the ignition lock cylinder and turn the ignition switch from OFF to RUN. Maintain the ignition switch in RUN for 3 seconds. This step programs the new key to a coded key.
6. If it is desired to program an additional key(s), wait 30 seconds and then repeat the key programming procedure from Step 1.
- If the programming of the new key is successful, the new coded key(s) starts the engine and the anti-theft indicator illuminates for 3 seconds and then goes out.
- If the programming of the key is not successful, the new coded key(s) does not start the engine and the anti-theft indicator flashes rapidly on and off. Repeat Steps 1 through Step 5. If the failure repeats, refer to Key Programming Using Diagnostic Equipment. Using Diagnostic Equipment
