What You’ll Need:

A small flathead screwdriver
Your 2017 VW Passat key fob

Step-by-Step Guide:

Open the Key Fob: Locate the small release button on the back of your key fob. It’s usually marked with a key symbol or a small arrow. Press the button and gently pull out the metal key blade.
Locate the Battery Compartment: With the key blade removed, you’ll see a small slot. Use your flathead screwdriver to carefully pry open the battery compartment cover.
