Part: Key

It often drives you crazy trying to find out how to change the battery in your car's key fob. Audi has a battery replacement system for the key fob that is quite complex but quick to execute. The key fob battery model is: flat lithium battery 3V. Let's move on to disassembling the key fob. Hold the key fob firmly between your fingers with both hands and press the lever located on the chrome part while sliding out the key usually used in emergencies. Once the key is extracted, you will notice a black protrusion that you need to grip with your fingers (like a clamp), press, and pull outward. Now that the battery compartment is out, you can replace the old battery with the new one. Reverse all the steps to reassemble the key fob.
