Are you struggling to lock or unlock your 2017 Audi A4? Is your dashboard displaying a key and battery symbol? It’s highly likely your Audi A4 key fob battery is running low and needs replacing. Don’t worry, replacing the battery in your 2017 Audi A4 key fob is a straightforward process you can often do yourself. This guide will walk you through the steps, ensuring you can get back to enjoying the convenience of your key fob in no time.
Step-by-Step Guide to 2017 Audi A4 Key Fob Battery Replacement
For the 2017 Audi A4, you’ll typically encounter a smart key fob, designed for keyless entry and ignition. Replacing the battery in this type of fob is simple and requires no special tools. Here’s how to do it:
-
Identify the Correct Battery: You will need a CR2032 battery. This is a common type of button cell battery, readily available at most drugstores, supermarkets, and online retailers.
-
Prepare Your Key Fob: Locate the small button or release catch on your Audi A4 key fob. This is usually found on the side or bottom of the fob, often near the metal key ring loop.
-
Release the Emergency Key: Press and hold the release button while simultaneously pulling out the mechanical emergency key blade. This key is a backup and is housed within the key fob.
-
Access the Battery Housing: Once the emergency key is removed, you’ll see a slot or opening where the key blade was located. This is where you will access the battery compartment.
-
Open the Fob Casing: Carefully insert a small flathead screwdriver or a similar thin, flat tool into the slot. Gently twist or pry to separate the two halves of the key fob casing. Avoid using excessive force to prevent damage to the plastic.
-
Locate and Remove the Old Battery: With the key fob casing open, you will see the CR2032 battery. Take note of the battery’s orientation – specifically, the positive (+) side. Gently pry under the edge of the battery to remove it from its housing. You can use your fingertip or the same small screwdriver, being careful not to damage the battery contacts.
-
Install the New Battery: Insert the new CR2032 battery, ensuring the positive (+) side is facing the same direction as the old battery was removed. It should snap easily into place.
-
Reassemble the Key Fob: Carefully align the two halves of the key fob casing and press them firmly back together until they snap securely closed.
-
Reinsert the Emergency Key: Slide the mechanical emergency key blade back into its slot until it clicks into place.
-
Test Your Key Fob: Test the buttons on your key fob to ensure they are now working correctly, locking and unlocking your 2017 Audi A4.
What If Your 2017 Audi A4 Key Fob Still Doesn’t Work?
If you’ve replaced the battery and your 2017 Audi A4 key fob is still not functioning, there are a couple of troubleshooting steps you can try:
- Check Battery Orientation: Double-check that you inserted the new CR2032 battery with the correct polarity (+ side up). A reversed battery will not work.
- Battery Freshness: Ensure the new battery is fresh and not expired. Sometimes batteries can lose charge while sitting on the shelf.
- Re-synchronize the Key Fob: In some cases, after a battery replacement, your Audi A4 key fob might need to be re-synchronized with your car. Try this simple re-initialization procedure:
- Manually unlock your 2017 Audi A4 using the emergency 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.
- Turn the ignition off and remove the key.
- Try using the key fob buttons again.
If these steps don’t resolve the issue, there might be a more complex problem with your key fob or your Audi A4’s receiver system.
2017 Audi A4 Key Fob Battery Replacement Cost
The good news is that replacing the battery in your 2017 Audi A4 key fob is very affordable. A CR2032 battery typically costs between $5 and $10, depending on the brand and retailer.

However, as you can see from this guide, it’s a simple DIY task that can save you time and money.
