What You’ll Need to Change Your Audi Key Fob Battery

Before you begin, gather the following items:

A new CR2032 battery: This is the most common type of battery for Audi key fobs. You can find them at most electronics or auto parts stores.
A small flat-head screwdriver: This will help you pry open the key fob casing.
Optional: A small plastic pry tool: This can help prevent scratching the key fob casing, but a screwdriver will work in a pinch.

Steps to Change the Battery in Your Audi Key Fob

While the specific design of Audi key fobs can vary slightly between models, the general process for changing the battery is generally the same. Here’s a general guide, followed by model-specific tips for those who need them:

Identify the release button: Look for a small button or switch on the back of your key fob. This releases the physical key.
Release the physical key: Press the release button and gently slide the physical key out of the fob.
Separate the key fob halves: With the physical key removed, you should see a small slot or indentation where the two halves of the key fob casing meet. Insert the flat-head screwdriver (or plastic pry tool) into this slot and gently pry the two halves apart.
Locate and replace the battery: Once the key fob is open, you’ll see the CR2032 battery. Carefully remove it, noting which side is facing up (+ or -). Insert the new battery in the same orientation.
Reassemble the key fob: Align the two halves of the casing and press them firmly together until you hear a click, indicating they’re securely closed.
Reinsert the physical key: Slide the physical key back into its slot on the key fob.
Test the key fob: Press the lock, unlock, and panic buttons on your key fob to make sure it’s functioning correctly.
