I noticed that my car key for my Audi A4 is not working, and I suspect that the battery might be dead. How do I go about changing the battery in my car key?
ReplyFirst, you will need to locate the battery cover on your car key. It is usually on the back of the key. Use a small flathead screwdriver to gently pry it off.
Once the battery cover is removed, you should see the battery. Carefully remove it and replace it with a new CR2032 battery.
Make sure the battery is inserted correctly with the positive (+) side facing up. Then, put the battery cover back on.
