GM Key and Transmitter Programming by Ignition Type

Regular key ignition (adds a key, keeps existing keys)

1. 1Insert the original, already-programmed key and start the engine.
2. 2Turn the key off and remove it.
3. 3Within 10 seconds, insert the new key and turn to ON (don't start).
4. 4The security light goes out once the key is programmed (it may be too quick to see). No security light? Wait 10 minutes and 45 seconds.
5. 5Repeat from step 1 for additional keys.

Push-button start — with at least one working transmitter

1. 1Place the recognized (working) transmitter in the cupholder.
2. 2Insert the new key into the driver's-door lock cylinder and turn to unlock five times within 10 seconds. The Driver Information Center shows READY FOR REMOTE #2–5.
3. 3Pull out the cupholder and place the new transmitter in the transmitter pocket beneath it.
4. 4Press the ignition. When learned, the display is ready for the next transmitter.
5. 5Remove the transmitter and press Unlock. To add more, repeat the last three steps. When done, press and hold the ignition 5 seconds to exit.

Push-button start — with no working transmitter

Takes about 30 minutes; up to 5 transmitters. Connect jumper cables or a charger — battery voltage drops during this procedure.

1. 1Insert the new key into the driver's-door lock cylinder and turn to unlock five times within 10 seconds. The display shows REMOTE LEARN PENDING, PLEASE WAIT.
2. 2Wait 10 minutes until the display shows PRESS ENGINE START BUTTON TO LEARN, then press the ignition. It shows REMOTE LEARN PENDING again.
3. 3Repeat the previous step two more times. After the third, all previous transmitters stop working and the display shows READY FOR REMOTE #1.
4. 4Pull out the cupholder and place the new transmitter in the transmitter pocket beneath it.
5. 5Press the ignition. When learned, the display is ready for the next transmitter.
6. 6Remove the transmitter and press Unlock. To add more, repeat the last three steps, then press and hold the ignition 5 seconds to exit.
