This guide will walk you through each step of the 2006 Audi A3 Key Fob Battery Replacement process, ensuring you get back to enjoying the convenience of your key fob in no time.
While some issues with your Audi key fob might require professional service, a battery replacement is often the only fix needed for a key fob that’s lost its range or become unresponsive. Before considering a trip to the dealership or booking a service appointment, let’s explore how to handle a 2006 Audi A3 key fob battery replacement yourself.
Step-by-Step Guide to Replacing Your 2006 Audi A3 Key Fob Battery
For the 2006 Audi A3, and many similar Audi models of this era, you’ll likely encounter one of two key fob styles: the flip key fob or the standard remote fob. Both are simple to open and replace the battery in with just a few common tools. Let’s break down the process for each type.
Replacing the Battery in a 2006 Audi A3 Flip Key Fob
The flip key fob is characterized by its retractable metal key blade. For this type of 2006 Audi A3 key fob battery replacement, you will need a CR1620 battery. These batteries are widely available at most drug stores, supermarkets, and of course, our parts center.
Here’s how to replace the battery:
-
Locate the Notch: On the side of your 2006 Audi A3 flip key fob, you’ll find a small notch or seam running along the edge of the casing.
-
Gently Pry Open the Casing: Using a flathead screwdriver, or even a thin coin, carefully insert the tip into the notch. Gently twist the screwdriver to separate the two halves of the key fob casing. Be careful not to apply excessive force to avoid damaging the plastic.
-
Separate the Halves: Once you’ve created a gap, carefully pull apart the two halves of the key fob. Set aside the half containing the metal flip key blade.
-
Open the Battery Compartment: You’ll now see the internal components and the battery compartment within the remaining half of the fob. There might be a second, smaller seam to open the battery compartment itself. Use your flathead screwdriver again to gently pry this compartment open.
-
Remove the Old Battery: Take note of the orientation of the battery – specifically, which side is facing up (positive or negative). This is crucial for correct installation of the new battery. You can use your fingertip or the tip of the screwdriver to gently lever out the old CR1620 battery.
-
Insert the New Battery: Install the new CR1620 battery, ensuring it’s placed in the same orientation as the old one. The positive (+) side usually faces upwards.
-
Reassemble the Key Fob: Carefully snap the battery compartment cover back into place, if applicable. Then, align the two halves of the key fob casing and press them firmly together until they click securely shut.
-
Test Your Key Fob: Try using your key fob to lock and unlock your 2006 Audi A3 to confirm the battery replacement was successful.

Replacing the Battery in a 2006 Audi A3 Standard Remote Fob
If your 2006 Audi A3 key fob is a standard remote without the flip-out key, the battery replacement is equally simple. This type of fob typically uses a CR2032 battery, which is also readily available.
Follow these steps for a standard 2006 Audi A3 remote fob battery replacement:
-
Locate the Key Release Button: On the standard remote fob, find the small button, often chrome or metallic, designed to release the emergency key.
-
Remove the Emergency Key: Press and hold the key release button and slide out the metal emergency key from the fob.
-
Pry Open the Fob: Once the emergency key is removed, you will see a notch or opening where the key was inserted. Insert the tip of your flathead screwdriver into this opening. Gently twist to separate the two halves of the key fob casing.
-
Separate the Casing: Carefully pull apart the two halves of the fob.
-
Remove the Battery Holder (if applicable): Depending on the exact design of your 2006 Audi A3 key fob, you might find the battery housed in a small plastic holder. If there is a holder, gently grip it and remove it from the fob.
-
Replace the Battery: Note the orientation of the old CR2032 battery before removing it. Install the new CR2032 battery in the same orientation.
-
Reassemble: If you removed a battery holder, place it back into the fob. Align the two halves of the key fob casing and press them together until they snap closed.
-
Reinsert Emergency Key and Test: Slide the emergency key back into the fob until it clicks into place. Test the key fob functions to ensure the new battery is working correctly.

What if My 2006 Audi A3 Key Fob Still Doesn’t Work?
After completing the 2006 Audi A3 key fob battery replacement, your key fob should ideally work immediately. However, in some rare cases, you might encounter issues. Here are a few troubleshooting tips:
- Battery Orientation: Double-check that you inserted the new battery in the correct orientation (+ and – sides matching the original).
- Battery Type: Ensure you’ve used the correct battery type (CR1620 or CR2032) as specified for your 2006 Audi A3 key fob.
- Clean Contacts: Inspect the metal contacts inside the key fob for any dirt or corrosion. If necessary, gently clean them with a cotton swab and a bit of rubbing alcohol.
- Synchronization: In some instances, especially after a prolonged period without battery power, your key fob might need to be resynchronized with your Audi A3. Refer to your owner’s manual for specific synchronization procedures, or try the method mentioned in the original article involving manually locking and unlocking the driver’s side door.
If you’ve tried these steps and your 2006 Audi A3 key fob is still not functioning, it might indicate a more complex issue requiring professional attention.
