5. Step-by-Step Guide to GMC Yukon Key Programming

Here’s a comprehensive guide to programming your GMC Yukon key fob, covering both manual methods and using diagnostic tools:

Method 1: Manual Programming (for some models)

1. Prepare Your Vehicle:

   • Close all doors.
   • Insert the working key into the ignition.

2. Enter Programming Mode:

   • Hold the UNLOCK button on the driver’s side door (do not release).
   • Quickly turn the ignition from ON to OFF twice.
   • Release the UNLOCK button. The door locks should cycle, indicating the vehicle has entered programming mode. If the locks cycle before you release the unlock button, repeat from step one.

3. Program the New Key Fob:

   • Press and hold the LOCK and UNLOCK buttons simultaneously on the new key fob until the vehicle responds by cycling the door locks (this may take up to 5 minutes for a new remote).

4. Program Additional Remotes (if needed):

   • Repeat step 3 for any additional remotes you wish to program.

5. Exit Programming Mode:

   • Turn the key to the ON position to exit programming mode.

6. Test:

   • Test all remotes to ensure they are working correctly.

Method 2: Using a Diagnostic Tool (Recommended for newer models)

1. Connect the Diagnostic Tool:

   • Plug your CARDIAGTECH diagnostic tool into the OBD-II port, usually located under the dashboard on the driver’s side.

2. Power Up the Tool:

   • Turn on the ignition (without starting the engine) to power up the diagnostic tool.

3. Navigate to Key Programming:

   • Use the tool’s interface to navigate to the key programming or remote programming section. This may be under “Security,” “Body Control,” or a similar category.

4. Follow On-Screen Instructions:

   • The diagnostic tool will provide step-by-step instructions specific to your GMC Yukon model. These instructions may include entering a security code or VIN (Vehicle Identification Number).

5. Program the Key Fob:

   • Follow the tool’s prompts to program the new key fob. This usually involves pressing certain buttons on the fob when prompted.

6. Test the Key Fob:

   • Once programming is complete, test the key fob to ensure it locks, unlocks, and starts the vehicle (if equipped with remote start).

6. Common Issues and Troubleshooting Tips

Even with careful execution, key programming can sometimes present challenges. Here are some common issues and troubleshooting tips:

• Vehicle Not Entering Programming Mode:

  • Ensure the key is fully inserted and the ignition is turned correctly.
  • Verify that the UNLOCK button is held down until instructed to release it.
  • Check your vehicle’s manual for specific instructions, as some models may have slight variations.

• Key Fob Not Responding:

  • Ensure the key fob has a fresh battery.
  • Double-check that you are pressing the correct buttons during programming.
  • Try moving closer to the vehicle during the programming process.

• Diagnostic Tool Errors:

  • Make sure the diagnostic tool is compatible with your GMC Yukon model.
  • Update the tool’s software to the latest version.
  • Verify the OBD-II connection is secure and free of debris.

• Security Code Issues:

  • Ensure you have the correct security code for your vehicle. This code can usually be found in your owner’s manual or by contacting a GMC dealer.

• General Tips:

  • Read the entire programming procedure before starting.
