This guide will walk you through the process, ensuring you can get back to enjoying the seamless access and security your Audi A5 offers.
Many Audi owners, particularly those with the A5 model, might encounter the need to replace their key fob battery. While the exact design can vary slightly across different Audi A5 model years and key fob styles, the fundamental process remains largely consistent. This article provides a comprehensive guide to help you change your Audi A5 Key Fob Battery efficiently.
Step-by-Step Guide to Replacing Your Audi A5 Key Fob Battery
Before you begin, you’ll need a few simple tools: a new CR2032 battery (the most common type for Audi key fobs) and a small flathead screwdriver or a similar prying tool. Let’s break down the process for different Audi key fob types you might encounter with your A5.
Replacing the Battery in a Standard Audi A5 Key Fob
This method applies to many Audi A5 key fobs, especially those without a visible key blade release button.
- Locate the Seam: Examine the edges of your Audi A5 key fob. You’re looking for a subtle seam that runs around the middle of the fob. This is where you’ll separate the two halves.
- Insert and Twist: Carefully insert the tip of your flathead screwdriver into the seam. Gently twist the screwdriver to begin separating the two halves of the key fob. Avoid using excessive force to prevent damage to the plastic casing.
- Open the Fob: Once you’ve created a small opening, you should be able to pry the two halves completely apart by hand.
- Identify the Battery: Inside, you’ll see the battery compartment. The CR2032 battery is usually held in place by small clips.
- Remove the Old Battery: Gently pry the old battery out of its compartment. Note the orientation of the battery (positive side up or down) before removing it.
- Install the New Battery: Place the new CR2032 battery into the compartment, ensuring it’s in the correct orientation (usually positive side facing upwards).
- Reassemble the Fob: Carefully snap the two halves of the key fob back together. You should hear a click as they securely join.
Replacing the Battery in an Audi A5 Key Fob with a Key Blade Release Button
Some Audi A5 key fobs feature a button to release a physical key blade. This type often has a slightly different battery replacement process.
- Release the Key Blade: Locate the key blade release button on your key fob. Press and hold this button while pulling out the metal key blade.
- Find the Notch: Look inside the key compartment where the metal key blade was housed. You should see a small notch or slot.
- Pry Open the Casing: Insert the tip of your flathead screwdriver into this notch. Gently twist or lever the screwdriver to pop open the battery cover.
- Remove the Cover: Once you’ve popped it open, you should be able to carefully remove the battery cover completely.
- Replace the Battery: Remove the old CR2032 battery and replace it with a new one, again noting the correct polarity.
- Reattach the Cover: Align the battery cover back into place and gently press until it snaps securely shut.
- Reinsert the Key Blade: Slide the metal key blade back into its housing until it clicks into place.
What To Do If Your Audi A5 Key Fob Isn’t Working After Battery Replacement
In most cases, replacing the battery will immediately restore your Audi A5 key fob’s functionality. However, if you find that your key fob is still not working after a battery change, there are a couple of troubleshooting steps you can try:
- Check Battery Orientation: Double-check that you installed the new CR2032 battery in the correct orientation. Incorrect polarity is a common reason for a key fob not to work.
- Re-synchronize the Key: Sometimes, the key fob may need to be re-synchronized with your Audi A5. Try this simple procedure:
- Manually unlock your Audi A5 using the physical key in the driver’s side door.
- Insert the key into the ignition.
- Turn the ignition to the “on” position (without starting the engine) for a few seconds, then turn it off.
- Remove the key and try using the key fob buttons again.
If these steps don’t resolve the issue, it’s recommended to consult with Audi service professionals. There might be a more complex issue requiring expert attention.
