Lost your key fob or need to program a new one for your 2008 GMC Sierra? Don’t worry, programming your 2008 Gmc Key Fob is a straightforward process you can do yourself, saving you a trip to the dealership. This guide provides clear, easy-to-follow instructions for programming your keyless entry remote, ensuring you regain convenient access to your vehicle quickly. There are two methods depending on whether your GMC Sierra is equipped with Driver Information Center (DIC) buttons. Follow the steps below that correspond to your vehicle’s features.
Programming Your 2008 GMC Key Fob with Driver Information Center Buttons
If your 2008 GMC Sierra has Driver Information Center buttons, typically located on the steering wheel, use this procedure to program your key fob:
- Ignition Ready: Insert your key into the ignition and turn it to the “ON” position. This is the position right before you start the engine. Ensure you can access the Driver Information Center display.
- Access Relearn Mode: Press the vehicle information button on your DIC controls repeatedly until the display reads “PRESS TO RELEARN REMOTE KEY”.
- Initiate Learning: Once “PRESS TO RELEARN REMOTE KEY” is displayed, press the “set/reset” button. The display should then change to “REMOTE KEY LEARNING ACTIVE”. This indicates your vehicle is now in programming mode and ready to learn the new key fob.
- Program the First Key Fob: Take your 2008 GMC key fob and simultaneously press and hold both the “lock” and “unlock” buttons. Continue holding both buttons for approximately 15 seconds. You should hear a chime sound, confirming that the remote has been successfully programmed.
- Program Additional Key Fobs (Optional): If you have additional 2008 GMC key fobs to program, repeat step 4 immediately. You can program up to a maximum of eight remotes for your 2008 GMC Sierra.
- Exit Programming Mode: To finalize the programming process, turn the ignition key to the “OFF” position and remove the key from the ignition.
- Test Your Remotes: Thoroughly test all programmed key fobs to ensure they are working correctly by locking and unlocking your doors and, if applicable, testing the remote start feature.
Programming Your 2008 GMC Key Fob Without Driver Information Center Buttons
If your 2008 GMC Sierra does not have Driver Information Center buttons, you’ll use the trip odometer reset stem to navigate the programming process. Ensure your vehicle is in Park (P) and the key is in the “ON” position (as far as it will go before starting the engine).
- Enter Relearn Mode: Press and release the trip odometer reset stem repeatedly until the Driver Information Center displays “RELEARN REMOTE KEY”.
- Activate Learning Mode: Press and hold the trip odometer reset stem for approximately three seconds. The message “REMOTE KEY LEARNING ACTIVE” will appear on the display, indicating the system is ready to program a new 2008 GMC key fob.
- Program the Key Fob: Take your first 2008 GMC key fob. Press and hold both the “lock” and “unlock” buttons simultaneously for about 15 seconds. A chime will sound to confirm successful programming.
- Program Additional Remotes (Optional): To program more key fobs, immediately repeat step 3 for each additional remote. Remember, a maximum of eight remotes can be programmed to your 2008 GMC Sierra.
- Exit Programming: Turn the ignition key to the “OFF” position and remove the key to exit the programming mode.
- Verify Programming: Test each programmed 2008 GMC key fob to confirm it operates the door locks and other remote functions as expected.
By following these simple steps, you can easily program your 2008 GMC key fob and regain full keyless entry functionality for your vehicle. Enjoy the convenience of your programmed remote!
