Identifying Your Audi A3 Key Fob Type
Before you begin, it’s important to identify the type of key fob you have for your Audi A3. While designs vary slightly over the years, most Audi A3 key fobs fall into one of these categories:
- Older Flip Key Fob: Typically found in older Audi A3 models, this fob has a physical key that flips out.
- Newer Flip Key Fob: A more modern version of the flip key, often sleeker and using a different battery type.
- Smart Keyless Entry Remote: This key fob offers keyless entry and start functionality and usually doesn’t have a flip-out key but may contain a removable emergency key blade.
The battery replacement process differs slightly for each type, so let’s look at each one in detail.
Replacing the Battery in an Older Audi A3 Flip Key Fob
If your Audi A3 uses an older flip key fob, here’s how to replace the battery:
-
Gather the Right Batteries: You’ll need two CR1620 batteries for this type of key fob.
-
Separate the Key Fob Halves: Carefully use a flathead screwdriver to gently pry apart the two halves of the key fob. Insert the screwdriver into the seam and twist gently.

-
Remove the Battery Cover: Use the flathead screwdriver again to carefully detach the battery cover. There might be a small notch to help you pry it open.
-
Replace the Old Batteries: Remove the old CR1620 batteries and insert the new ones. Ensure you place them with the positive (+) side facing up.
-
Reattach the Battery Cover: Snap the battery cover back into place until it clicks securely.
-
Reassemble the Key Fob: Press the two halves of the key fob back together until they snap shut.
Replacing the Battery in a Newer Audi A3 Flip Key Fob

-
Get a CR2032 Battery: You will need one CR2032 battery for this newer style key fob.
-
Open the Metal Key: Press the key release button to flip out the metal emergency key blade.
-
Find the Notch: Look inside the key compartment where the metal key was housed. You’ll see a small notch.

-
Close the Key Fob: Carefully align the plastic notches and gently press the battery cover back onto the key fob until it snaps closed.
Replacing the Battery in an Audi A3 Smart Keyless Entry Remote
If your Audi A3 uses a smart keyless entry remote, follow these steps for battery replacement:

-
Remove the Metal Key Blade: Locate the release button or latch to remove the metal emergency key blade from the key fob.
-
Locate the Notch: Look in the area where the metal key blade was removed. You’ll find a small notch.

Snap the Key Fob Back Together: Carefully press the two halves of the key fob shell back together until they snap securely closed.
What to Do If Your Audi A3 Key Fob Still Isn’t Working
In most cases, replacing the battery will solve the problem. However, if your Audi A3 key fob still isn’t recognized after a battery replacement, you may need to reinitialize it. Here’s a simple reinitialization procedure you can try:
- Manual Door Lock: Insert the key into the driver’s side door lock.
- Manually Lock and Unlock: Use the key to manually lock and then unlock the door.
- Press Unlock Button: Remove the key from the door and press the “unlock” button on the key fob.
If your key fob still doesn’t work after trying this, it’s best to contact the service experts at Audi Fletcher Jones for assistance. There might be a more complex issue requiring professional attention.
