Using Two Programmed Keys

KEY PROGRAMMING USING TWO PROGRAMMED KEYS

NOTE:
- This procedure works only if 2 or more programmed ignition keys are available and it is desired to program additional key(s). If 2 keys are not available, refer to Key Programming Using Diagnostic Equipment. 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. Refer to Anti-Theft Security Access and select SPARE KEY PROGRAMMING SWITCH: ENABLED. Anti-Theft Security Access Switch State Control
- 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) will not start the vehicle and the THEFT indicator flashes. If the programming procedure was not successful, repeat the key programming procedure from Step 1. If the failure repeats, refer to Diagnosis and Testing to review the DTCs and carry out the pinpoint tests as necessary. Passive Anti-Theft System (PATS)
- A maximum of 8 ignition keys can be programmed to a passive anti-theft system (PATS)-equipped vehicle. If more keys are needed, refer to Key Programming Switch State Control. Switch State Control
- If the steps are not carried out as described, the programming procedure will end.
- Ignition keys must have correct mechanical key cut for the vehicle and must be PATS encoded keys.
- If the vehicle is in unlimited key mode, this spare key 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 and turn the ignition from OFF to ON (maintain the ignition in ON for 1 second).
2. Turn the ignition to OFF and remove the first key from the ignition lock cylinder.
3. Within 10 seconds of turning the ignition to OFF, insert the second programmed ignition key into the ignition and turn the ignition from OFF to ON (maintain the ignition in ON for 1 second).
4. Turn the ignition to OFF and remove the second key from the ignition lock cylinder.
5. Within 20 seconds of turning the ignition to OFF, insert the unprogrammed ignition key (new key) into the ignition and turn the ignition from OFF to START (attempt to start the vehicle).
6. If it is desired to program additional keys, repeat the key programming procedure from the beginning.
