Replacing your 2012 Audi A7 key fob battery at home can save you time and money compared to visiting a dealership for a simple battery change. The key to a smooth replacement is understanding the specific type of key fob your 2012 Audi A7 uses and the correct battery it requires. Let’s dive into the steps.
Step-by-Step Guide to Replacing Your 2012 Audi A7 Key Fob Battery
For the 2012 Audi A7, you’ll typically encounter a smart key fob. This type of key fob is designed for keyless entry and ignition, and replacing its battery is a simple procedure. Here’s how to do it:
-
Identify the Battery Type: You’ll need a CR2032 battery for your 2012 Audi A7 key fob. This is a common type of coin cell battery readily available at most drugstores, supermarkets, and online retailers.
-
Gather Your Tools: You’ll need a small flathead screwdriver or a similar thin tool to open the key fob. A soft cloth can also be helpful to prevent scratches.
-
Remove the Emergency Key Blade: Locate the small release button on your key fob. Press and hold this button while simultaneously pulling out the metal emergency key blade. This blade is used for manual door unlocking in case of battery failure, and removing it provides access to the battery compartment.
-
Open the Key Fob Casing: Once the emergency key blade is removed, you’ll see a small notch or slot where the blade was housed. This is where you’ll insert your flathead screwdriver.
Carefully insert the tip of your flathead screwdriver into this notch. Gently twist the screwdriver to pry open the key fob casing. Work slowly and patiently to avoid damaging the plastic. The casing is usually snapped together and should separate with a gentle twisting motion.
-
Access the Battery Compartment: With the casing open, you’ll see the battery compartment. The CR2032 battery will be visible inside.
-
Remove the Old Battery: Note the orientation of the old battery (usually positive side up). You can use your fingertip or the edge of the flathead screwdriver to gently pry out the old CR2032 battery.
-
Insert the New Battery: Take your new CR2032 battery and insert it into the compartment, ensuring the positive (+) side is facing upwards, matching the orientation of the old battery. Push the battery firmly into place until it’s securely seated.
-
Reassemble the Key Fob: Carefully snap the two halves of the key fob casing back together. Ensure they are firmly closed and that there are no gaps. You should hear a click as the casing pieces join correctly.
-
Replace the Emergency Key Blade: Slide the metal 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 working correctly. Try locking and unlocking your 2012 Audi A7 remotely. The key fob should now be functioning with the new battery.
What if Your 2012 Audi A7 Key Fob Still Isn’t Working?
In most cases, replacing the battery will solve the issue. However, if your 2012 Audi A7 key fob still isn’t working after a battery replacement, there are a couple of things you can try:
-
Re-initialization: Sometimes, after a battery change, the key fob may need to be re-synchronized with your car. Refer to your Audi A7 owner’s manual for specific re-initialization instructions. A common method involves manually locking and unlocking the driver’s side door with the emergency key and then pressing the unlock button on the fob.
-
Check Battery Orientation and Type: Double-check that you’ve installed the CR2032 battery correctly, with the positive side up. Also, ensure you’ve used the correct CR2032 battery type.
If you’ve tried these steps and your 2012 Audi A7 key fob remains unresponsive, there might be a more complex issue. In such cases, it’s best to consult with Audi service professionals.
