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 an additional key(s). If 2 keys are not available, follow the procedure in Key Programming Using Diagnostic Equipment.
- The spare key PID must be enabled for this procedure to operate. If this PID is not enabled, follow the anti-theft security access procedure and select Spare Key Programming Switch: Enabled.
- If the programming procedure is successful, the new key(s) starts the vehicle and the THEFT indicator illuminates for approximately 3 seconds.
- If the programming procedure is not successful, the new key(s) does not start the vehicle and the THEFT indicator flashes. If the programming procedure is not successful leave the ignition switch in the ON 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 diagnostic trouble codes (DTCs) and carry out pinpoint tests as required.
- A maximum of 8 ignition keys can be programmed to a passive anti-theft system (PATS) equipped vehicle in normal mode. If more are required, refer to Key Programming Switch State Control. Switch State Control
- If the steps are not carried out as described, the programming procedure ends.
- Ignition keys must have the correct mechanical key cut for the vehicle and must be PATS encoded keys.
- 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 key from OFF to ON (maintain the key to ON for 3 seconds, but no more than 10 seconds).
2. Turn the key to OFF and remove the first coded key from the ignition lock cylinder.
3. Within 10 seconds of turning the key to OFF, insert the second programmed ignition key into the ignition lock cylinder and turn the key from OFF to ON (maintain the key in ON for 3 seconds, but no more than 10 seconds).
4. Turn the key to OFF and remove the second coded key from the ignition lock cylinder.
5. Within 20 seconds of turning the key to OFF, insert the unprogrammed ignition key (new key/valet key) into the lock cylinder and turn the key from OFF to ON (maintain the key in ON for 3 seconds). This step programs the new key to the vehicle.
6. If it is desired to program an additional key(s), wait at least 20 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 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 theft indicator flashes on and off. Repeat Steps 1 through Step 5.If the failure repeats, refer to Key Programming Using Diagnostic Equipment. Using Diagnostic Equipment
