### 10-Minute Vehicle Key Learn

Note:

• | This procedure will only learn the vehicle keys. This procedure will not learn the immobilizer pre-release password or the challenge/response data. Do not use this procedure as a substitute for a 10-minute relearn when replacing or reprogramming a body control module (BCM) or engine control module (ECM).

• | A total of 8 keys may be programmed to a single vehicle.

• | This procedure adds keys only. The procedure does not erase previously learned keys.

• | The keys to be learned must duplicate the mechanical cut of the current key.

This 10-minute learn procedure should be used when a new vehicle key is desired to be programmed.

1. Connect a scan tool to the vehicle.
2. Turn ON the ignition, with the engine OFF.
3. Ensure that all power consuming devices are turned OFF on the vehicle.
4. On the scan tool, select Service Programming System and follow the on-screen instructions. Ensure the correct programming selection is chosen based on component being replaced or programmed. For this procedure, go to the BCM Configuration/Reset Functions menu and choose the Configure New Module or Remove/Reset Module selection.
5. At this point the scan tool must remain connected for the duration of the 10-minute learn procedure.

Note:

• | The scan tool will initially display 12 Minutes. The first 2 minutes allow the scan tool to initialize the appropriate control module. The remaining 10 minutes is the relearn timer.

• | On some vehicles the security indicator may be illuminated for the duration of the 10-minute learn procedure.

6. Observe the scan tool, after approximately 10 minutes the scan tool will display "Programming Successful, Turn OFF Ignition". The vehicle is now ready to learn the key information and/or the passwords on the next ignition switch transition from OFF to CRANK.
7. With a scan tool, clear any DTCs.
