Replacing it is a quick and easy fix you can usually handle yourself. This guide will walk you through how to change a VW key fob battery step-by-step, saving you time and money.

Understanding Your VW Key Fob

There are a few different styles of Volkswagen key fobs, but don’t worry, the battery replacement process is generally quite similar.

Finding the Battery Compartment

Most VW key fobs have a dedicated slot or release button for the battery compartment.

  • Flip-style keys: Look for a small release button or slider on the back.
  • Traditional key fobs: Check for a notch or groove that you can use to pry open the battery cover.

“Many times, customers assume their key fob is faulty when it’s a simple battery issue,” says Master Automotive Technician, Mark Schmidt. “Knowing how to access and replace the battery can be a real time-saver.”
