  • Patience: This process can take a few minutes, so be prepared to follow the steps carefully.

Step-by-Step Programming Instructions

Now, let’s get down to the nitty-gritty of programming your 2003 Chevy Avalanche key fob.

1. Insert the Original Key: Insert the key that came with your Avalanche into the ignition.

3. Press the Unlock Button: While the ignition is in the “ON” position, press the “Unlock” button on the **original** key fob once.

4. Press the Lock Button: Immediately after pressing the “Unlock” button, press the “Lock” button on the **original** key fob twice.

5. Turn the Ignition Off: Turn the ignition off.

6. Repeat Steps 1-5: Now, repeat steps 1-5 using the **new** key fob that you want to program.

Troubleshooting Common Issues

Sometimes, the programming process doesn‘t go as smoothly as planned. Here are some common issues and their solutions:

  • Key Fob Not Recognized: If the vehicle doesn’t respond to your key fob, ensure the battery is fresh and properly installed. Sometimes, the key fob’s internal circuitry can malfunction, requiring a replacement.
  • Programming Not Successful: If the key fob doesn’t work after following the steps, repeat the entire process carefully. Double-check that you are using the correct key fob and that the steps are completed in the correct order.
  • Multiple Key Fobs: If you have multiple key fobs, you can program them one at a time by repeating the steps for each fob.

Additional Tips for Successful Programming

  • Clear Programming Memory: If you have previously programmed key fobs that are no longer in use, it’s a good idea to clear the programming memory before attempting to program a new key fob. This can be done by following the same steps but using the original key fob twice in a row.
