- Turn the key counterclockwise to the unlock position five times within 10 seconds. On some vehicles, you may need to remove the lock cylinder cap on the driver door handle to access the door lock.
Wait for the DIC Message:
- The Driver Information Center (DIC) will display READY FOR REMOTE # 2, 3, 4, etc.
Place the New Smart Key:
- Put the new smart key into the transmitter pocket. For GMC Acadia vehicles, this is usually in the front cupholder.
Press the ENGINE START/STOP Button:
- Press the ENGINE START/STOP button. When the new smart key is recognized, the DIC will display that it is ready to program the next smart key.
Remove and Test the Smart Key:
- Remove the smart key from the transmitter pocket and press the LOCK or UNLOCK button on the remote.
Program Additional Smart Keys:
- To program additional smart keys, repeat Steps 5-7.
Exit Programming Mode:
- When all additional smart keys are programmed, press and hold the ENGINE START/STOP button for approximately 12 seconds to exit programming mode.

- If you have no existing smart keys, have the emergency key blade in your new smart key cut by a locksmith before proceeding.
Remove the Key Blade:
- Take out the key blade from your existing or new smart key.
Insert and Turn the Emergency Key Blade:
- Insert the emergency key blade into the driver’s door lock cylinder.
- Turn the key counterclockwise to the unlock position five times within 10 seconds. You might need to remove the lock cylinder cap on the driver door handle to access the door lock.
Wait for the DIC Message:
- The Driver Information Center (DIC) will display READY FOR REMOTE # 2, 3, 4, etc.
Wait 10 Minutes:
- Wait for 10 minutes until the DIC displays PRESS ENGINE START BUTTON TO LEARN, then press the ENGINE START/STOP button.
- The DIC display will again show REMOTE LEARN PENDING, PLEASE WAIT.
Repeat the Wait:
- Repeat Step 5 two more times. After the third time, all previously known smart keys will no longer work with the vehicle. The remaining smart keys can be re-programmed during the next steps.
- The DIC display should now show READY FOR REMOTE # 1.
Place the New Smart Key:
- Put the new smart key into the transmitter pocket (front cupholder for GMC Acadia vehicles).
Press ENGINE START/STOP:
- Press the ENGINE START/STOP button. When the smart key is recognized by the vehicle, the DIC display will show that it is ready to program the next smart key.
Remove and Test the Smart Key:
- Remove the smart key from the transmitter pocket and press the LOCK or UNLOCK button on the smart key.
Program Additional Smart Keys:
- To program an additional smart key, repeat Steps 7-9.
Exit Programming Mode:
- When all additional smart keys are programmed, press and hold the ENGINE START/STOP button for approximately 12 seconds to exit programming mode.

2.3. Troubleshooting Common Programming Issues

Even with careful execution, you might encounter issues during the programming process. Here are some common problems and their solutions:

DIC Not Displaying the Correct Message:
- Issue: The DIC does not display the expected READY FOR REMOTE message.
- Solution: Ensure the key blade is turned the correct number of times within the specified time frame. Double-check that the emergency key blade is fully inserted into the lock cylinder.
Key Fob Not Recognized:
- Issue: The vehicle does not recognize the new key fob when placed in the transmitter pocket.
- Solution: Ensure the key fob battery is new and properly installed. Try repositioning the key fob in the transmitter pocket.
Programming Mode Not Exiting:
- Issue: Unable to exit the programming mode after completing all steps.
- Solution: Ensure the ENGINE START/STOP button is held down for the full 12 seconds. Verify that all key fobs you want to be programmed have been successfully added.
Vehicle Not Starting After Programming:
- Issue: The vehicle does not start after programming a new key fob.
- Solution: Ensure the key fob is correctly programmed to the vehicle. Check that the emergency key blade is properly cut and matches the vehicle’s ignition system.

By addressing these common issues, you can increase your chances of successfully programming your 2018 GMC Acadia key fob.
