How to Replace the Key Fob Battery for an Audi

Model: Audi Tt MK 2, 8J - Years 2006-2014
Part: Key

To replace the key fob battery for an Audi vehicle (this video demonstrates on an Audi TT), first, remove the key from its designated slot. Inside the key slot, there is a specific groove that allows you to use something like a pen to press and lift the small plastic cover protecting the battery and its compartment. Once lifted, you can fully open the battery cover using a kitchen knife, for example. At this point, you have access to the battery and can replace it with a new one. To reassemble, simply follow the steps shown in the images in reverse order.
