Identifying Your VW Key Fob Type

Before you begin, it’s important to identify the type of key fob you have. Volkswagen has used several different key fob designs over the years. Knowing your specific key fob type will ensure you follow the correct battery replacement procedure. Some fobs have a visible slot for a coin or flathead screwdriver, while others require a small release button to be pressed.

Gathering the Necessary Tools

You’ll need a few simple tools to change your VW key fob battery. Typically, this includes a small flathead screwdriver or a coin and a new CR2032 battery. It’s crucial to use the correct battery type, as using the wrong one could damage your key fob.

Steps to Change Your VW Key Fob Battery

The process of changing the battery is generally straightforward.

Locate the Release Button/Slot: Examine your key fob and find the small release button or slot. This is often located on the side or back of the fob.
Open the Key Fob: Insert the flathead screwdriver or coin into the slot and gently twist or pry open the key fob casing. Be careful not to force it, as this could damage the plastic. For fobs with a release button, press the button and gently separate the two halves of the key fob.
Remove the Old Battery: Once the key fob is open, you should see the old CR2032 battery. Gently pry it out using your screwdriver or fingernail. Avoid touching the battery terminals.
Install the New Battery: Insert the new CR2032 battery, making sure the positive (+) side is facing upwards, just like the old battery.
Close the Key Fob: Align the two halves of the key fob and press them together until they snap shut.

Check the Battery Orientation: Ensure the new battery is installed correctly with the positive (+) side facing up.
Clean the Battery Contacts: Use a cotton swab and rubbing alcohol to clean the battery contacts inside the key fob.
