Key with Integrated Transmitter Programming

Keys can be programming in various ways using the procedures outlined below. Using the Replacing Keys procedures will first erase all the known keys from the vehicle. Any existing keys and any new keys will then be programmed. This procedure should be used any time a key is required to be unlearned or erased from a vehicle. If a new key is being learned to a vehicle to replace a damaged, inoperative, or stolen key, the Replacing Keys procedure must be used. This ensures that the old key cannot be used to access or start the vehicle after programming.

The Adding Keys procedure does not erase any keys prior to programming. The procedure will simply program the key into the next available slot. The Adding Keys procedure should only be used when adding an additional key to the vehicle. The Adding Keys procedure should never be used to program a key to a vehicle that is having a key replaced, regardless of the cause for the replacement.

Replacing Keys (With SPS)

Note:

•	This procedure will unlearn all previously learned keys. All keys that are to be programmed must be with the vehicle.

•	This procedure may be used with or without existing learned keys being present.

•	This procedure will take more than 15 minutes to complete.

•	A total of 8 keys maybe be learned to a single vehicle.

•	This procedure will only learn the vehicle key information. This procedure will not learn any immobiliser information between the body control module (BCM) and engine control module (ECM).

•	If the battery voltage is low, charge the battery before continuing with the procedure.

Connect a scan tool to the vehicle and access SPS. Refer to Service Programming System (SPS) .
Ensure that all power consuming devices are turned OFF on the vehicle.
Select the SPS application and follow the onscreen instructions.
Select Reprogram ECU.
Select IMMO Immobilizer Learn - Setup.
Select the Program Transponder or Remote Key (Delete) function.

Note:

•	At multiple times during the learn procedure, SPS will instruct you to turn the vehicle to the Service Mode position. Make sure the vehicle is actually in the Service Mode before continuing on the SPS terminal. If the igniting is not in the run mode, the learn procedure will fail.

•	The key slot is located inside the upper instrument panel storage compartment. The rubber mat lining at the bottom of the compartment needs to be removed to access the slot.

Follow the on-screen instructions.
After programming all keys, Programming Complete, is displayed.
Press and hold the ignition mode switch for 15 seconds.
Press the lock and unlock button on each key that was programmed. This will awaken each key and allow passive and active keyless entry functions to be established.
With a scan tool, clear any DTCs.
Verify each key is operating properly. Operate each of the keyless entry functions using the buttons on the key and then start the vehicle. When verifying operation, make sure that no other keys are near the vehicle.
