How do you replace the battery of the Audi A3 key?

The inability to open the central locking of one's car is most often due to a flat remote control battery, except for some exceptions, such as cold solder joints, internal circuit breakage, and so on. Changing the battery, in the case of an Audi A3, is within everyone's reach, as can be seen in the video provided here, there is no need to go to a workshop. After removing the emergency key, we point a small flathead screwdriver at a predetermined point, push upwards, and lift a part of the aforementioned remote control cover.
