How to change the battery in an Audi A6 key fob?

I recently purchased a used Audi A6 and the battery in the key fob needs to be changed. Can someone walk me through the process step by step and share any tips or tricks they have found?

To change the battery in an Audi A6 key fob, first you will need a flathead screwdriver. Use the screwdriver to gently pry open the key fob. Inside, you will see the old battery. Use the screwdriver again to carefully remove the battery and replace it with a new one. Make sure the new battery is facing the same direction as the old one. Close the key fob back up and test to make sure it is working.

I have found that using a small plastic tool, like a credit card or gift card, is less likely to scratch or damage the key fob when opening it. You can also use this tool to carefully push the old battery out and place the new one in without the need for a screwdriver.

I have had good luck using a small amount of rubbing alcohol on a cotton swab to clean the contacts inside the key fob before replacing the battery. This can help improve the connection and make the key fob work more efficiently.
