How do I change the key remote battery in my Audi A1?

I've noticed that my Audi A1 key remote is not working as well as it used to. I've replaced the batteries before in my previous car but I'm not sure how to do it for the Audi A1. Can someone provide some guidance?

To change the battery in your Audi A1 key remote, first find a small flathead screwdriver and pop open the remote's back cover. You should see a small battery or batteries inside, depending on the model of your remote. Carefully remove the old battery and replace it with a new one. Be sure to match the polarities correctly. Finally, snap the cover back on and test the remote.

Changing the key remote battery in your Audi A1 is fairly easy, but make sure you have the correct battery size to avoid any mishaps. You can usually find the battery type on the inside of the back cover. Once you have the correct battery, gently pry open the cover and replace the old battery with the new one. Make sure to not touch the battery with your fingers as the oils can cause it to fail prematurely.
