Why is My VW Key Fob Not Working?

Several reasons can cause your VW key fob to malfunction.

Replacing the battery in your VW key fob is usually straightforward. While the exact process may vary slightly depending on the model, the general steps are similar.

  1. Locate the release button: This is usually a small button or switch on the side or back of the key fob.
  2. Separate the key fob halves: Press the release button and gently separate the two halves of the key fob. You may need a small flathead screwdriver to pry them apart.
  3. Identify the battery: Once the key fob is open, you’ll see the battery. Note the type of battery (usually a CR2032) for replacement.
  4. Remove the old battery: Carefully remove the old battery using your fingernail or a small screwdriver. Avoid damaging the battery contacts.
  5. Install the new battery: Insert the new battery, ensuring the positive (+) side faces up, matching the orientation of the old battery.
