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 additional programmed key(s) are desired. 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. For additional information, 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) start the vehicle and the THEFT indicator illuminates for approximately 3 seconds.
- If the programming procedure is not successful, the new key(s) do not start the vehicle and the THEFT indicator flashes. If the programming procedure was not successful, leave the ignition switch in the RUN position for at least 30 seconds then repeat the key programming procedure from Step 1. If the failure repeats, refer to Diagnosis and Testing to review the DTCs and carry out 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 are needed, 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 the correct PATS encoded key for the vehicle.
- 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 unlimited number of additional keys.

1. Insert a programmed ignition key into the ignition lock cylinder and turn the ignition switch from the OFF position to the RUN position (maintain the ignition switch in the RUN position for 3 seconds, but not longer than 10 seconds).
2. Turn the ignition switch to the OFF position and remove the first key from the ignition lock cylinder.
3. Within 10 seconds of turning the ignition switch to the OFF position, insert a second programmed ignition key into the ignition lock cylinder and turn the ignition switch from the OFF position to the RUN position (maintain the ignition switch in the RUN position for 3 seconds, but not longer than 10 seconds).
4. Turn the ignition switch to the OFF position and remove the second key from the ignition lock cylinder.
5. Within 20 seconds of turning the ignition switch to the OFF position, insert the unprogrammed ignition key (new key) into the ignition lock cylinder and turn the ignition switch from the OFF position to the RUN position (attempt to start the vehicle).
6. If additional programmed key(s) are desired, repeat the key programming procedure.
