Identifying Your Audi A6 Key Fob Type
Before we dive into the battery replacement, it’s helpful to understand the type of key fob your Audi A6 uses. While designs can vary slightly depending on the year and trim of your A6, most Audi A6 models utilize a smart key fob. These key fobs are designed for keyless entry and push-button start, offering convenience and advanced features.
Generally, you’ll encounter one of these common Audi key fob styles for your A6:
- Advanced Key Fob: This is the most common type for newer Audi A6 models, featuring a sleek design with buttons for locking, unlocking, trunk release, and panic alarm. It may or may not have a physical key blade that slides out.
- Flip Key Fob (Less Common on Newer A6): Older Audi A6 models might use a flip key fob where the physical key blade folds out from the fob. These also have buttons, but the battery replacement process can differ slightly.
Regardless of the exact style, the fundamental process for an Audi A6 key fob battery change remains similar. The key is to carefully open the fob casing to access the battery compartment.
Step-by-Step Guide: Audi A6 Key Fob Battery Replacement
For most Audi A6 key fobs, you’ll need a CR2032 battery. This is a common and readily available 3V lithium coin cell battery that you can purchase at most drugstores, supermarkets, and online retailers. It’s always a good idea to have a fresh CR2032 battery on hand when you decide to perform this replacement.
Here’s how to change the battery in your Audi A6 key fob:
- Gather Your Tools: You’ll need a new CR2032 battery and a small flathead screwdriver or a similar thin, flat tool. A soft plastic trim tool is ideal to avoid scratches, but a small screwdriver will work carefully.
- Locate the Release Latch or Notch: Examine your Audi A6 key fob closely. Look for a small release latch, button, or a subtle notch. This is usually located on the side or bottom edge of the key fob, often near the keyring attachment.
- Release the Emergency Key (If Applicable): If your key fob has a physical emergency key blade, remove it. There’s usually a small button or slider to release it. Removing the key blade often reveals the notch or access point for opening the fob.
- Open the Key Fob Casing:
- Using a Notch: If you find a notch, gently insert the tip of your flathead screwdriver or trim tool into the notch. Apply slight twisting pressure to carefully pry the key fob casing open. Work your way around the seam, gently separating the two halves of the fob.
- Using a Release Latch/Button: If your fob has a latch or button, press and hold it while gently pulling apart the two halves of the key fob casing.
- Identify the Battery Compartment: Once the casing is open, you’ll see the internal components and the battery compartment. The battery is usually easily visible and held in place by small clips or a retainer.
- Remove the Old Battery: Carefully note the orientation of the old battery (positive side up or down). Gently pry the old battery out of its compartment. You might be able to use your fingertip or the flathead screwdriver to help dislodge it.
- Install the New Battery: Insert the new CR2032 battery into the compartment, ensuring the correct orientation (match the positive and negative sides to how the old battery was placed). The positive side of the CR2032 battery is usually marked with a “+” symbol.
- Reassemble the Key Fob: Carefully snap the two halves of the key fob casing back together. Ensure they are firmly closed and that all latches or clips are securely engaged.
- Test Your Key Fob: Press the buttons on your key fob to test if it’s working correctly. Try locking and unlocking your Audi A6 remotely and starting your vehicle if it has keyless start.
What To Do If Your Audi A6 Key Fob Still Doesn’t Work
In most cases, replacing the battery will solve the issue. However, if your Audi A6 key fob still isn’t functioning after a battery change, here are a few troubleshooting steps:
- Battery Orientation: Double-check that you inserted the new CR2032 battery in the correct orientation. Incorrect polarity can prevent the key fob from working.
- Battery Quality: Ensure you are using a fresh, high-quality CR2032 battery from a reputable brand. Old or low-quality batteries might not provide sufficient power.
- Key Fob Re-synchronization: In rare cases, the key fob might need to be re-synchronized with your Audi A6 after a battery change. Refer to your Audi A6 owner’s manual for specific instructions on key fob re-synchronization or initialization. A common method involves manually locking and unlocking the driver’s side door with the physical key blade.
- Professional Assistance: If you’ve tried these steps and your key fob remains unresponsive, there might be a more complex issue. It’s best to consult with a qualified Audi technician or your local Audi dealership. They have specialized tools and expertise to diagnose and resolve key fob problems.
Audi A6 Key Fob Battery Replacement Cost
The cost of an Audi A6 key fob battery change is minimal if you do it yourself. A CR2032 battery typically costs between $5 to $10, making this a very affordable DIY fix.

Dealerships or service centers will charge for labor in addition to the battery cost.
