The good news – the team at Volkswagen La Crosse can help! Check out our guide below on how to take on a VW key fob battery replacement, and don’t hesitate to reach out to our service team if you have any questions.

Which VW Key Battery Will I Need?

Knowing how to change the battery in a VW key fob isn’t a hard task, but you’ll want to know which VW key battery to use. Learn which product to purchase below:

  • If you drive an older VW vehiclewith a VW key fob that looks like a regular Volkswagen car key, you’ll need a CR1632 battery.
  • Most new models made after 1999 will use a fob that looks like a small pod with buttons on one side and a retractable emergency key. These fobs will likely need a CR2032 Battery.

VW Key Battery Replacement: Step-by-Step

No matter what VW vehicle you drive, replacing the battery is simple. You’ll need a small screwdriver and a new CR2032 battery. Avoid damaging and scratching your VW key fob by wrapping the flat-head screwdriver with a small piece of tape.

When you’re ready to get started, follow these steps:

  1. Press the button on your VW key fob until the emergency key pops out.
  2. Hold the key fob firmly in your hand, or attach it to a small metal key ring that you can hang onto with your index finger.
  3. Find the seam which connects the lid and the base of your fob. Create a small distance between the two with your fingers, and then use the flat-head screwdriver to finish prying them apart. Try not to scratch the inside.
  4. Take out the dead battery and insert the new one, with the positive side facing downward.
  5. Close the remote case tightly to hold everything in place, and then get back on the road!

How to Start the Car Without Your Smart Key

If you’re having trouble getting your key fob to work after pressing it over and over again, the VW key battery is likely dead. Even older key fobs will have an emergency key or a bayonet key, and you won’t need battery power to use it. Even if your vehicle has a keyless entry or a push button start feature, hold the emergency key below the ignition, and you should be able to start the engine.
