How do you replace the battery in the Audi A4 key?

Model: Audi Q4 MK 1 - Years 2021-2026
Part: Key

In the video guide provided here, we find images regarding the replacement of the battery for the key/remote control of Audi cars in general, so it can also be used as a reference for the Audi Q4. Let's see what to do: press the appropriate button located on the back of the remote control, extract the emergency key, take a flathead screwdriver and use it to pry open the back of the remote control, in order to lift it off for removal. Once this is done, we will have access to the battery, and all we need to do is remove the old one and install the new one.
