Open the Key Fob
When it’s time to replace your Volkswagen key fob battery, the first step is to open the key fob securely. Here’s a breakdown of how you can do this effectively:
- Locate the Seam: Gently examine your key fob to find the seam where the two halves meet.
- Use the Tool: Take your small flat-head screwdriver or prying tool to carefully insert it into the seam.
- Apply Gentle Pressure: Once the tool is in place, exert gentle pressure to separate the two halves of the key fob.
- Mindful Opening: Be cautious as you open the key fob to ensure you don’t damage the casing or internal components.

Replace the Battery
To begin, you’ll need a new coin cell battery matching the one you’re replacing. Ensure it’s the right size and type to avoid issues later on.
Next, locate the battery compartment. In most Volkswagen key fobs, it’s typically found in the back panel.
Gently remove the old battery. Be mindful of any clips or mechanisms securing it in place. Avoid using excessive force to prevent damage.

Before inserting the new battery, check its orientation. Make sure the positive and negative sides align correctly with the markings or diagram in the compartment.
Carefully place the new battery into the slot. A light press should secure it in place. Ensure it sits flat and doesn’t move around.
Once the new battery is in, reassemble the key fob by joining the two halves together. Make sure they align properly before applying pressure to snap them back into place.
Test the Key Fob
- Test Remote Functions: Make sure all buttons (unlock, lock, trunk release) respond when pressed.
- Check Range: Test the key fob at various distances from your car to confirm the signal range.
- Verify Car Locks: Ensure the key fob correctly locks and unlocks the vehicle.
- Test Alarm: Activate and deactivate the car alarm to confirm proper functionality.
- Replace Case: If the key fob doesn’t work after battery replacement, consider replacing its case.
