Using Two Programmed Keys
KEY PROGRAMMING USING TWO PROGRAMMED KEYSNOTE:
- This procedure works only if 2 or more programmed ignition keys or integrated 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.
- If this procedure is used to install a new passive anti-theft system (PATS) key or integrated key when a key is lost or damaged and all the keys are not available, the damaged or lost key can still start the vehicle. If the key being replaced is available, cut the key through the mechanical key cuts to prevent unauthorized use. To make sure a lost or damaged key no longer starts the vehicle or operates the remote keyless entry (RKE) system, use the diagnostic tool to erase all the keys.
- The spare key PID must be enabled for this procedure to operate. If the PID is not enabled, follow the security access procedure.
- If the programming procedure is successful, the new key(s) starts the vehicle and the THEFT indicator illuminates for approximately 3 seconds. If the new key is an integrated key, the RKE transmitter portion of the key locks and unlocks the doors, opens the luggage compartment and sounds the panic alarm.
- If the programming procedure is not successful, the new key(s) does not start the vehicle and/or the RKE transmitter does not operate. The THEFT indicator may also flash. If the programming procedure is 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 diagnostic trouble codes (DTCs) and carry out pinpoint tests as necessary.
- A maximum of 8 ignition keys can be programmed to a PATS equipped vehicle. The number of integrated keys cannot exceed 4 with the balance being standard PATS keys. If more standard PATS keys are needed, refer to Key Programming Switch State Control. If an attempt to program more than 4 integrated keys occurs the smart junction box (SJB) sets a memory full DTC. If the vehicle is equipped with a message center the instrument cluster displays the message INT KEY COULD NOT PROGRAM. The PATS portion of the additional key functions, but the RKE transmitter is not programmed. 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 additional PATS key.
1. Insert a programmed ignition key into the ignition lock cylinder and turn the key from the OFF position to the RUN position (leave the key in the RUN position for 3 seconds, but not longer than 10 seconds).
2. Turn the key to the OFF position and remove the first key.
3. Within 10 seconds of turning the key to the OFF position, insert a second programmed ignition key into the ignition lock cylinder and turn the key from the OFF position to the RUN position (leave the key in the RUN position for 3 seconds, but not longer than 10 seconds).
4. Turn the key to the OFF position and remove the second key.
5. Within 20 seconds of turning the key to the OFF position, insert the unprogrammed ignition key (new key) into the ignition lock cylinder and turn the key from the OFF position to the RUN position. Leave the key in the RUN position for a minimum of 6 seconds then attempt to start the vehicle.
6. If additional programmed key(s) are desired, repeat the key programming procedure.
