4. Step-by-Step Guide to Programming a GMC Sierra Key Fob

Here’s a comprehensive guide to programming your GMC Sierra key fob, ensuring you can do it efficiently.

4.1. Manual Programming Method

This method is suitable for older GMC Sierra models that do not require advanced programming tools.

Gather All Fobs: Ensure you have all key fobs you wish to program. The programming sequence will erase all previously programmed remotes, so you must include all existing and new fobs.
Enter Programming Mode:
- Close all the doors of your GMC Sierra.
- Insert the key into the ignition.
- Press and hold the “UNLOCK” button on the driver’s side door panel. Do not release it until instructed.
- Quickly turn the ignition to the “ON” position (just shy of starting the vehicle) and then to the “OFF” position. Repeat this “ON,” “OFF” sequence two more times (ON, OFF, ON, OFF).
- Release the “UNLOCK” button. The vehicle should respond by automatically locking and unlocking, indicating that the programming mode has been successfully entered.
- If the locks do not cycle, remove the key, open the door, and return to Step 1.
Program the Key Fob:
- Once in programming mode, immediately press and hold both the “LOCK” and “UNLOCK” buttons on the first key fob simultaneously.
- Continue holding the buttons until the door locks cycle again, indicating that the fob has been programmed. This may take up to 30 seconds.
- Repeat this step for each additional key fob you wish to program.
Exit Programming Mode:
- After programming all the key fobs, turn the ignition to the “ON” position. This action exits the programming mode.
- Turn the ignition to the “OFF” position and remove the key from the ignition.
Test the Key Fobs:
- Test each key fob to ensure it is functioning correctly. Verify that the lock, unlock, and remote start (if applicable) functions work as expected.
- If any key fob does not work, repeat the programming steps for that particular fob.

4.2. Using a Programming Tool

For newer models, a programming tool may be necessary to interface with the vehicle’s computer system.

Connect the Tool: Plug the programming tool into the OBD-II port, usually located under the dashboard.
Follow Prompts: The tool will guide you through the programming steps. Follow the instructions carefully.
Enter Security Code: You may need to enter a security code, which can be found in your vehicle’s manual or obtained from a dealership.
Program Fobs: Follow the tool’s instructions to program each key fob.
Test: Test each fob to ensure it is working correctly.

4.3. Common Issues and Troubleshooting

Fob Not Responding: Ensure the battery is good and properly installed.
Vehicle Not Entering Programming Mode: Make sure the doors are closed correctly and the ignition is turned on and off quickly enough.
