Understanding Your 2015 Audi A4 Key Fob

The key fob for the 2015 Audi A4 is a sophisticated piece of technology, much more than just a simple key. It integrates keyless entry, remote start (if equipped), and panic functions.

Why Replace the Battery Yourself?

• A new CR2032 battery: Make sure it’s a fresh one for optimal performance.
• A small flathead screwdriver or a plastic pry tool: This will help you open the key fob casing without damaging it.
• A small flashlight (optional): This can help you see the battery compartment and its components more clearly.
