How to Program a 2021 Cadillac XT6 Ignition Smart Chip Key Transponder

Step by Step How to Programming Instructions:

Programming with Programmed Keys:
To program a new key to the vehicle when there are two programmed keys, follow these steps:
1. Place the two programmed keys in the front cupholder.
2. Remove the key lock cylinder cap on the driver door handle. Insert the vehicle key of the new remote into the key lock cylinder on the outside of the driver door and turn the key to the unlock position five times within 10 seconds. The Driver Information Center (DIC) displays “READY FOR REMOTE #2, 3, 4, or 5,” etc.
3. Place the new key into the transmitter pocket with the buttons facing toward the rear of the vehicle. The transmitter pocket is inside the center console storage area.
4. Press ENGINE START/STOP. When the key is learned, the DIC will show that it is ready to program the next key.
5. Remove the key from the front cupholder and press UNLOCK or LOCK on the key. To program additional keys, repeat Steps 3–5. When all additional keys are programmed, press and hold ENGINE START/STOP for 12 seconds to exit programming mode.
6. Return the vehicle key back into the remote.

Programming without Programmed Keys:
If two currently programmed keys are not available, follow this procedure to program up to eight keys. This feature is not available in Canada. This procedure will take approximately 30 minutes to complete. The vehicle must be off and all of the keys you wish to program must be with you.
1. Remove the key lock cylinder cap on the driver door handle. Insert the vehicle key of the remote into the key lock cylinder on the outside of the driver door and turn the key to the unlock position five times within 10 seconds. The DIC displays “REMOTE LEARN PENDING, PLEASE WAIT.”
2. Wait for 10 minutes until the DIC displays “PRESS ENGINE START BUTTON TO LEARN” and then press ENGINE START/STOP. The DIC displays will again show “REMOTE LEARN PENDING, PLEASE WAIT.”
3. Repeat Step 2 two additional times. After the third time, all previously programmed keys will no longer work with the vehicle. Remaining keys can be reprogrammed during the next steps. The DIC display should now show “READY FOR REMOTE #1.”
4. Place the new key into the transmitter pocket with the buttons facing toward the rear of the vehicle. The transmitter pocket is inside the center console storage area.
5. Press ENGINE START/STOP. When the key is learned, the DIC will show that it is ready to program the next key.
6. Remove the key from the front cupholder and press UNLOCK or LOCK on the remote. To program additional keys, repeat Steps 4–6. When all additional keys are programmed, press and hold ENGINE START/STOP for 12 seconds to exit programming mode.
7. Return the vehicle key back into the remote.
