To change the battery for the Audi A4 remote, start by inserting a small flathead screwdriver into the slot under the manufacturer's logo and pry off the lower part of the remote. Once the lower part is removed, open the section with the buttons and locate the battery. Use the flathead screwdriver to pry it out from the bottom. Place the new battery in the same position as the old one. Close the button section of the remote until you hear a click, then attach the lower part to the top until you hear another click.
