Is your Audi key fob struggling to lock or unlock your doors? A dead or dying battery is often the culprit. Fortunately, replacing the battery in your Audi key fob is a straightforward task you can easily handle at home. This guide, brought to you by the experts at keyfobx.com, will walk you through the process for various types of Audi key fobs, ensuring you regain full remote control of your vehicle.
Different Audi Key Fobs, Different Batteries: Understanding Your Key
Audi, known for its innovation and sophisticated engineering, utilizes different key fob designs across its models. While the core function remains the same, the battery replacement procedure can vary slightly depending on the type of key you own. This guide covers the most common Audi key fob types: the Remote Key, the Smart Keyless Entry Remote, and the Flip Key. Regardless of which type you have, you’ll likely need a common coin cell battery, readily available at most drugstores or online retailers. Let’s dive into how to change the battery in each.
Replacing the Battery in an Audi Remote Key Fob
The Audi Remote Key is a classic design, often featuring a metal key blade that flips out. Here’s how to replace its battery:
-
Flip Out the Metal Key: Locate the release button or mechanism on your key fob and flip out the metal key blade as if you were going to use it to manually unlock your door.
-
Access the Back Cover: Look for a small black cover, often near the base of the key blade hinge. You’ll need to use a small screwdriver or a similar tool to gently press and potentially slide this cover to release it.
-
Remove the Back Cover: Once released, carefully pop off the back cover of the key fob. This might require a little prying with your fingernail or the edge of a small tool.
-
Locate and Remove the Old Battery: With the back cover removed, you’ll see the battery compartment. The old battery, typically a CR2032 coin cell battery, will be visible. Gently pry out the old battery. You can use the tip of a small screwdriver, being careful not to damage the surrounding components.
-
Insert the New Battery: Take a new CR2032 battery and insert it into the battery compartment. Ensure the positive (+) side of the battery is facing upwards, as indicated by the markings in the compartment.
-
Reattach the Back Cover: Carefully align the back cover and snap it back into place. Ensure it is securely closed.
-
Test Your Key Fob: Flip the metal key blade back in and test your key fob by attempting to lock or unlock your Audi remotely. It should now be working perfectly.

Changing the Battery in an Audi Smart Keyless Entry Remote
The Audi Smart Keyless Entry Remote offers enhanced convenience features like keyless entry and start. Replacing its battery is slightly different:
-
Release and Remove the Metal Key Blade: On the chrome part of your Smart Key fob, you’ll find a key release button or lever. Press and hold this while simultaneously pulling out the metal key blade from the fob shell.
-
Expose the Battery Holder: Once the metal key blade is removed, you’ll see a plastic battery holder exposed on the fob. Carefully remove this plastic piece. It might slide off or require gentle prying, depending on the model.
-
Access and Remove the Old Battery: With the battery holder removed, the battery will be accessible. Like the Remote Key, it typically uses a CR2032 battery. Carefully remove the old battery from its housing.
-
Insert the New CR2032 Battery: Place the new CR2032 battery into the battery holder, ensuring the positive (+) side is facing upwards.
-
Reassemble the Key Fob: Put the plastic battery holder back onto the fob shell, ensuring it clicks or slides securely into place.
-
Reinsert the Metal Key Blade: Slide the metal key blade back into its slot in the fob until it clicks and locks securely.
-
Test the Key Fob Functionality: Test the key fob’s functions, including keyless entry, remote locking/unlocking, and starting your vehicle (if applicable for your model). Everything should now be functioning correctly.

Replacing the Battery in an Audi Flip Key Fob
The Audi Flip Key fob is another common design, characterized by its flip-out metal key and often a more rounded shape compared to the Remote Key. Here’s the battery replacement process:
-
Separate the Fob Case: Use a flathead screwdriver or a thin plastic pry tool to carefully separate the two halves of the key fob case. Insert the tool into the seam running around the fob and gently twist or pry to split the case open.
-
Set Aside the Key Blade Side: Once open, take the side of the fob that contains the flip metal key blade and set it aside for the moment. You’ll be working with the other half of the case.
-
Separate the Shell to Access the Battery: On the remaining half of the fob case, you may need to further separate the shell to expose the battery compartment. Use your screwdriver or pry tool again to gently separate this shell.
-
Remove the Old Battery: Inside, you’ll find the battery. For Flip Keys, this is often a CR1620 battery, which is slightly thinner than a CR2032. Carefully remove the old CR1620 battery.
-
Insert the New CR1620 Battery: Insert a new CR1620 battery into the compartment, ensuring the positive (+) side is facing upwards.
-
Reassemble the Shell: Press the shell back together until you hear a snapping sound, indicating it’s securely closed.
-
Rejoin the Fob Halves: Finally, put the two halves of the key fob case back together and press firmly until they snap closed.
-
Test Your Flip Key Fob: Test all the buttons and functions of your flip key fob to ensure the new battery is working and your key is back to its optimal functionality.
