Identifying Your 2012 Audi A6 Key Fob Type
Before you begin, it’s helpful to identify the type of key fob your 2012 Audi A6 uses. While Audi key fobs can vary slightly across models and years, for the 2012 A6, you’ll likely have one of two main types:
- The Flip Key Fob: This type features a metal key blade that flips out from the fob body when a button is pressed.
- The Smart Key Fob (Keyless Entry Remote): This more modern style often has a more rounded design and is primarily used for keyless entry and ignition, with a removable emergency key blade.
While the internal components and battery type are often similar, the opening mechanism may differ slightly. This guide will cover the battery replacement process for both common types found with the 2012 Audi A6.
Step-by-Step Guide to 2012 Audi A6 Key Fob Battery Replacement
Regardless of the specific style of your 2012 Audi A6 key fob, you’ll generally need a small CR2032 battery. This is a common and readily available coin-cell battery that you can purchase at most drugstores, supermarkets, and online retailers. You’ll also need a small flathead screwdriver or a similar thin, flat tool to help open the key fob casing.
Here’s a general guide to replacing the battery in your 2012 Audi A6 key fob:
Replacing the Battery in a 2012 Audi A6 Flip Key Fob

Gather Your Tools and Battery: You’ll need a new CR2032 battery and a small flathead screwdriver.
-
Flip Out the Key Blade: Press the button on your key fob to flip out the metal key blade.
-
Locate the Notch: Look for a small notch or seam on the key fob casing. This is usually located on the side of the fob, near where the key blade folds into the body.

Open the Casing: Carefully insert the tip of your flathead screwdriver into the notch. Gently twist or pry to separate the two halves of the key fob casing. Be patient and avoid using excessive force to prevent damaging the plastic.
-
Access the Battery Compartment: Once the casing is open, you’ll see the internal components and the battery compartment. The battery is usually held in place by small clips.

What to Do If Your 2012 Audi A6 Key Fob Isn’t Recognized After Battery Replacement?
In most cases, replacing the battery is all you need to do to restore your 2012 Audi A6 key fob functionality. However, in some rare situations, your car might not immediately recognize the key fob after a battery change. This is usually due to a temporary loss of synchronization.
Here’s a simple re-initialization procedure you can try:
- Manual Door Lock: Insert the key blade into the driver’s side door lock.
- Manually Lock and Unlock: Use the key to manually lock and then unlock the driver’s side door.
- Test the Remote: Remove the key from the door and try pressing the “unlock” button on your key fob.
This process often resynchronizes the key fob with your 2012 Audi A6. If your key fob still isn’t working after trying this, it’s possible there might be another issue, or the battery replacement wasn’t successful.
2012 Audi A6 Key Fob Battery Replacement Cost
The good news is that replacing your 2012 Audi A6 key fob battery is very affordable. The CR2032 batteries themselves are inexpensive, typically costing between $5 and $10 for a pack, depending on the brand and quantity.
