Replacing Your Audi A6 Key Battery: A Step-by-Step Guide
The exact procedure for Audi key battery replacement can slightly differ depending on the specific style of your Audi A6 key fob. While many Audi key fobs share similar designs across models like the Q3, Q5, and Q7, the battery replacement process can vary. Although consulting your Audi A6 owner’s manual is always recommended for the most precise instructions, we’ll cover the general methods for the three most common types of Audi key fobs you might encounter with your A6.
Changing the Battery in Older Audi A6 Flip Key Fobs
If your Audi A6 is an older model and uses a flip key, the battery replacement process is usually as follows. These older flip keys typically require two 1620 batteries.
- Gather Your Tools and Batteries: You will need a small flathead screwdriver and two new 1620 batteries.
- Open the Key Fob: Carefully use the flathead screwdriver to gently pry apart the two halves of the key fob casing. Insert the screwdriver into the seam and twist gently.
- Locate the Battery Cover: Identify the half of the key fob that does not contain the flip key itself. This section will have a separate battery cover.
- Remove the Battery Cover: Again, using your flathead screwdriver, carefully detach the battery cover from the key fob. There might be a small notch to help you get started.
- Replace the Batteries: Remove the old 1620 batteries. Take note of how they are positioned (usually positive side up). Install the new 1620 batteries in the same orientation.
- Reassemble the Key Fob: Snap the battery cover back into its place. Then, align the two halves of the key fob casing and press them firmly together until they click shut.

Replacing the Battery in Newer Audi A6 Flip Key Fobs
Newer Audi A6 models with flip keys generally use a different type of battery and a slightly modified opening mechanism. These typically require a CR2032 battery.
- Obtain a CR2032 Battery: Make sure you have a new CR2032 battery ready.
- Flip Out the Metal Key: Press the key release button on your Audi A6 key fob to flip out the hidden metal key blade.
- Find the Notch: With the metal key flipped out, look for a small notch located inside the key compartment.
- Pry Open the Battery Cover: Insert a small flathead screwdriver into the notch and gently twist to pop open the battery cover.
- Remove the Cover: Once popped open, carefully pry the cover away from the back of the fob, near the keyring loop.
- Replace the CR2032 Battery: Remove the old CR2032 battery and insert the new one. Ensure the positive (+) side of the battery is facing upwards.
- Reattach the Cover: Carefully align the plastic notches on the cover with their corresponding slots on the key fob and gently press the cover back into place until it snaps shut.

Changing the Battery in Audi A6 Smart Keyless Entry Remote Fobs
For Audi A6 models equipped with a smart keyless entry remote, the battery replacement steps are also quite simple and usually involve a CR2032 battery.
- Get a CR2032 Battery: Have a new CR2032 battery ready for replacement.
- Remove the Metal Key Blade: Locate the release button or latch on your smart key fob and remove the metal key blade from the fob shell.
- Locate the Notch: Look in the area where the metal key blade was housed. You will find a small notch.
- Open the Fob Shell: Insert a flathead screwdriver into the notch at an angle, pointing towards the center of the key fob.
- Pry Open the Shell: Carefully rotate the screwdriver to gently separate and pop open the key fob shell into two halves.
- Replace the CR2032 Battery: Remove the old CR2032 battery and replace it with the new one, making sure the positive (+) side is facing upwards.
- Snap the Fob Back Together: Align the two halves of the key fob shell and press them firmly together until they snap securely back into place.

Audi A6 Key Fob Not Recognized After Battery Change?
In some instances, your Audi A6 might not immediately recognize the key fob after you’ve replaced the battery. If this happens, don’t worry. You can try to re-initialize the key. Here’s a simple method that often works:
- Manual Door Lock: Insert the metal key blade into the driver’s side door lock.
- Manual Lock and Unlock: Manually use the key to unlock and then immediately lock the door.
- Unlock Button Press: Remove the key from the door and press the “unlock” button on your key fob.
This process can sometimes resynchronize the key fob with your Audi A6’s system. If you continue to experience issues, it’s recommended to consult with Audi service professionals for assistance.
