Do you need to replace the key battery of your Audi Q3 and don't know how? I'm here to help.

Place the key in the operating position and separate the shell using a flat screwdriver or a plastic lever. Now use the screwdriver to pry out the battery and replace it with the new one, ensuring the correct polarity. Finally, reattach the separated shell and test the remote's functionality near the car.
