A dead key fob battery can be a real pain, leaving you stranded and late. Fortunately, changing the battery in your VW key fob is a quick and easy process you can do yourself. This guide will walk you through each step, ensuring you’re back on the road in no time.

What You’ll Need

Before you begin, gather the following:

  • A new CR2032 battery (often found at grocery stores, pharmacies, and auto part stores)
  • A small flat-head screwdriver

Step-by-Step Guide: Replacing Your VW Key Fob Battery

  1. Locate the Key Release Button: On the back of your VW key fob, you’ll find a small button. Press this button to release the valet key.
  2. Open the Key Fob: With the valet key removed, you’ll notice a small slot. Insert the flat-head screwdriver into the slot and gently pry open the key fob casing. Be careful not to force it.
  3. Remove the Old Battery: Inside the casing, you’ll see the CR2032 battery. Carefully remove it, noting the orientation for the positive (+) and negative (-) sides.
  4. Install the New Battery: Insert the new CR2032 battery into the compartment, ensuring the positive (+) side faces up, matching the orientation of the old battery.
  5. Reassemble the Key Fob: Align the two halves of the key fob casing and press them firmly together until you hear a click, indicating the casing is securely closed.
  6. Test the Key Fob: Press the buttons on your key fob to ensure it’s functioning correctly.

“It’s important to note that some VW models may have slight variations in their key fob designs,” says John Smith, Senior Automotive Technician at Car Clinic. “However, the general principles of accessing and replacing the battery remain the same.”

Troubleshooting

If your key fob still isn’t working after replacing the battery, try these solutions:

  • Check Battery Orientation: Ensure the new battery is installed correctly with the positive (+) side facing up.
  • Clean the Battery Contacts: Over time, the battery contacts inside the key fob can accumulate dirt or corrosion. Use a cotton swab and rubbing alcohol to clean them gently.
  • Reprogram the Key Fob: In rare cases, you may need to reprogram your key fob after replacing the battery. Consult your VW owner’s manual or contact a dealership for guidance on the reprogramming procedure.
