1. Gather the necessary tools. You will need a small flathead screwdriver, a new CR2032 battery, and a soft cloth.
2. Locate the key fob's battery compartment. It is usually located on the back of the key fob, under a small plastic cover.
3. Use the flathead screwdriver to gently pry open the battery compartment cover.
4. Remove the old battery from the compartment. Be careful not to touch the metal contacts on the battery with your fingers.
5. Insert the new battery into the compartment, positive side up.
6. Replace the battery compartment cover and press it down until it snaps into place.
7. Test the key fob to make sure it is working properly.
Here are some additional tips for changing the battery in a Volkswagen key fob:
* If the battery compartment cover is difficult to open, you can try using a thin piece of plastic, such as a credit card, to pry it open.
* Be careful not to drop the old battery. If you do, it could damage the key fob.
* If the new battery does not work, make sure that it is inserted correctly. The positive side of the battery should be facing up.
* If you are still having trouble changing the battery, you can take your key fob to a Volkswagen dealer for assistance.
