Step-by-Step Guide: How to Replace Battery in Key Fob 2012 Audi

Here’s a detailed step-by-step guide on how to replace the battery in your 2012 Audi key fob:

1. Locate the release button or slot: Examine your key fob for a small release button or slot. This is often located on the side or back of the fob.

2. Release the key: If your key fob has a physical key, press the release button and gently slide the key out. This will expose the seam where the key fob casing separates.

3. Separate the casing: Carefully insert your flathead screwdriver (or similar tool) into the seam and gently pry the two halves of the casing apart. Be careful not to damage the plastic.

4. Identify the battery: Locate the battery inside the key fob. It should be clearly visible and easily accessible.

5. Remove the old battery: Gently pry the old battery out of its compartment. Be careful not to damage the contacts. If the battery is stuck, try using a small piece of tape or a plastic tool to help lift it out.

6. Install the new battery: Place the new CR2032 battery into the compartment, ensuring the positive (+) side is facing upwards, just like the old battery. Press down gently until it clicks into place.

7. Reassemble the key fob: Carefully align the two halves of the casing and press them together until they snap shut.

8. Test the key fob: Try locking and unlocking your car to ensure the new battery is working correctly. If it doesn’t work, double-check the battery installation and try again. Sometimes, your key fob may not be working for other reasons. Check out this article for more information: when your key fob doesn’t work.
