How to Change the Key Battery of an Audi A4?

Model: Audi A4 B7 - Years 2004-2008
Part: Key

The procedure shown in the video is useful for replacing a dead battery in the Audi A4 key, but it also works for other remotes structured similarly. It requires very little time, no specific skills, and almost no tools except for a flathead screwdriver or similar tool, and of course, a new button battery. To proceed with the replacement, find the designated slot to insert the screwdriver to use as a lever to open the remote. The battery is visible; simply remove it, replace it with the new one, and finally, close the remote by applying slight pressure.
