• Original Key Fob: You’ll need your original working key fob to initiate the programming process.
• Patience: Programming can take a few minutes, so be patient and follow the steps carefully.

Step-by-Step Programming Instructions:

4. Introducing the New Fob: Now, take your new key fob and press and hold the “UNLOCK” button until the horn beeps once. This signifies that the new key fob has been successfully programmed.
5. Confirmation is Key: To confirm that the programming was successful, test your new key fob by locking and unlocking the doors. The vehicle’s horn should beep once when you press the “UNLOCK” button.

Troubleshooting Common Issues: When Programming Goes Awry

Sometimes, despite following the instructions meticulously, the programming process might not go as smoothly. Here are some common issues and their solutions:

• The Horn Doesn’t Beep: If the horn doesn’t beep during the programming process, it could indicate a problem with the battery in your original key fob or a faulty key fob. Ensure the battery in the original key fob is fresh and try the programming sequence again.
• The Programming Doesn’t Take: If the new key fob doesn’t respond after programming, try repeating the process. If the issue persists, there might be a problem with the new key fob itself. Consider purchasing a new one from a reputable dealer.

Additional Tips for Success:

• Battery Check: Before starting the programming process, ensure that both your original and new key fobs have fresh batteries. Weak batteries can lead to programming errors.
• Clear Signals: Make sure that the key fobs are within close proximity to the vehicle during the programming process. Avoid obstacles between the key fob and the car.
• Professional Help: If you encounter persistent issues, don’t hesitate to consult a qualified mechanic or an authorized Hummer dealership. They can diagnose any underlying problems and ensure proper programming.
