How do I replace the battery in my Audi Q7?

My Audi Q7 key fob stopped working and I suspect it's because the battery needs to be replaced. How can I do this on my own without going to the dealership?

Replacing the battery in your Audi Q7 key fob is a fairly simple process. First, locate the small slot on the edge of the fob and use a flathead screwdriver or a coin to open it. Then, carefully remove the old battery and replace it with a CR2032 battery, making sure the positive (+) side is facing up. Finally, close the fob and test it to see if it's working properly.

Before replacing the battery in your Audi Q7 key fob, make sure to have a replacement battery on hand and to avoid touching the new battery with your bare hands, as this can reduce its lifespan. It's also a good idea to clean the contacts in the key fob with rubbing alcohol before inserting the new battery.
