Whether you drive a recent model or an older Audi A6, understanding how to change your key fob battery can save you time and the inconvenience of a dealership visit. Let’s dive into the simple steps to get your Audi A6 key fob working like new again.
Identifying Your Audi A6 Key Fob Type
Before you begin, it’s important to identify the type of key fob you have for your Audi A6. While specific designs may vary slightly across Audi A6 model years, they generally fall into two main categories:
- Flip Key Fob: Common in older Audi A6 models, this type features a metal key blade that flips out from the fob body.
- Smart Key/Keyless Entry Remote: Prevalent in newer Audi A6 vehicles, this fob often lacks a visible, flip-out metal key (though a hidden emergency key is usually present). These are sometimes called “advanced keys” or “comfort access keys.”
Knowing your key fob type will ensure you follow the correct battery replacement procedure. Let’s explore the steps for each type.
How to Replace the Battery in an Audi A6 Flip Key Fob
If your Audi A6 uses a flip key fob, here’s how to change the battery:
-
Gather Your Tools and Battery: You’ll need a small flathead screwdriver and the correct replacement battery. For older Audi A6 flip key fobs, you’ll typically need two CR1620 batteries. Newer flip key fobs often use a single CR2032 battery. Check your owner’s manual or the battery compartment for the exact type.
-
Open the Key Fob: Locate the seam running around the center of your key fob. Carefully insert the flathead screwdriver into this seam. Gently twist the screwdriver to separate the two halves of the key fob.
-
Access the Battery Compartment: Once open, identify the battery cover. It’s usually a small, separate compartment within one half of the fob.
-
Remove the Battery Cover: Use the flathead screwdriver again to carefully pry open the battery cover. There might be a small notch or clip to release.
-
Replace the Old Batteries: Remove the old CR1620 or CR2032 batteries. Note the orientation (+ and – sides). Install the new batteries in the same orientation.
-
Reassemble the Key Fob: Snap the battery cover back into place. Align the two halves of the key fob and press them firmly together until they click shut.

Steps to Replace the Battery in an Audi A6 Smart Key/Keyless Entry Remote
For Audi A6 models with a smart key or keyless entry remote, follow these steps to replace the battery:
-
Identify the Battery Type: Smart key fobs for the Audi A6 almost universally use a CR2032 battery. Confirm this by checking your owner’s manual or the battery compartment markings if accessible.
-
Remove the Emergency Key Blade: Locate the small release button or latch on your key fob. Press and hold this while pulling out the metal emergency key blade.
-
Locate the Notch: Look inside the key fob shell where the metal key blade was housed. You’ll find a small notch or slot.
-
Pry Open the Fob: Insert the flathead screwdriver into the notch. Carefully twist the screwdriver to gently pry open the key fob casing. Avoid using excessive force to prevent damage.
-
Open the Casing Further: Once the initial opening is created, you can often use your fingers or the screwdriver to gently separate the two halves of the key fob completely.
-
Battery Replacement: Remove the old CR2032 battery. Observe the positive (+) side orientation. Install the new CR2032 battery with the positive side facing the same way.
-
Reassemble the Smart Key Fob: Carefully align the two halves of the key fob casing and press them together until they snap securely shut. Reinsert the emergency key blade until it clicks into place.

Reinitializing Your Audi A6 Key Fob (If Necessary)
In most cases, your Audi A6 key fob should work immediately after a battery replacement. However, if you find that your car doesn’t recognize the key fob, you might need to reinitialize it. Here’s a simple method you can try:
-
Manual Door Lock Re-sync: Insert the key blade (either the flip key blade or the emergency key from the smart key) into the driver’s side door lock.
-
Manual Lock and Unlock: Manually turn the key to lock and then unlock the door.
-
Test Remote Functions: Remove the key from the door and press the “unlock” button on your key fob. The car should respond, indicating successful re-initialization.
If this re-initialization process doesn’t work, or if you continue to experience issues with your Audi A6 key fob, it’s recommended to consult with an Audi service professional.
Audi A6 Key Fob Battery Cost and Professional Service
The cost of a replacement audi a6 key fob battery itself is minimal. A CR2032 or CR1620 battery typically costs between $5 to $15, depending on the brand and retailer. You can purchase these batteries at most drug stores, supermarkets, and online retailers.
While replacing the battery yourself is cost-effective, if you prefer professional assistance, or if you encounter any difficulties, Audi dealerships and certified mechanics can perform the audi a6 key fob battery replacement for you. Keep in mind that service costs will apply, which can vary by location and dealership.
For complex issues beyond battery replacement, such as key fob programming problems or a malfunctioning key fob, professional diagnostics and service are essential.
