To replace the battery of the key/remote for the Audi TT, there are a few simple steps to follow. First, extract the actual key (metal) from its housing by rotating it around its pivot.

Now, in the space left behind, you can see a small indentation. Insert a small tool (like a pen, as shown in the video images, or a screwdriver) into it and push against the small cover, featuring the automaker's logo, until the cover unlocks from its position.

At this point, take a kitchen knife and pry up on the same cover, but from the side of the ring for attaching the keychain. With the cover removed, you can take out the battery located inside.

After replacing the old battery with the new one, reassemble everything and you're done!
