The replacement of the battery of the remote control of an Audi A4 car does not require great skills and is an operation really within the reach of anyone. As the author of the video shown here explains, the first thing to do is to remove the mechanical key from the remote control, pressing the appropriate side button and pulling from both ends of the remote control.

Once the key is removed, you can also remove the button battery, replace it with a new one of the same type, and then reassemble everything. The only precaution: make sure to use a battery with the same characteristics as the old one.
