Do you know what happens when your Volkswagen key fob battery dies? You're stuck in the car, unable to lock or unlock it. It's frustrating and embarrassing. Luckily, there are different ways you can do to prevent this from happening. Keep on reading to learn how to change a battery on the Volkswagen key fob.

How to replace a Volkswagen key fob battery?

Batteries are a necessary part of life. They power our phones, keep us company on long car rides and prevent us from being locked out of the house. But batteries don't last forever – they have a shelf-life that is dependent on what kind of battery it is. 

The Volkswagen Key Fob is a handy device that can be used to lock and unlock your car, as well as open the trunk. However, just like any other electronic device, it requires a battery replacement. Here's how to replace the battery of your Volkswagen Key Fob.

1) Push the metal button on the key to flip it open, and then separate the part of the key away from the section that has the buttons by adjusting both ends with your hands. You can use a screwdriver to split these two parts but wrap around a tape on the tip of the screwdriver to make sure you don't scratch the key fob while doing the process.

2) Get the portion where the buttons are and split it in half to see the circuit board and the battery compartment.

3) Use the tip of the flathead screwdriver to pop out the old battery. Don't forget to dispose of the old battery in a proper way as it's harmful if it gets swallowed by accident.

4) Replace the battery with the new one. This key fob uses a CR2032 3V battery. These are tiny disc-shaped batteries. Make sure that you slide in the battery in the compartment the right way. If you put it in the wrong way, your key fob will not work and might even harm other components on the circuit board.

5) Once you have inserted the new battery, reassemble everything back to normal with reverse order of steps so that they can lock properly.

When done correctly, your key fob will spring to life once again. Keep this in mind, as you can use these instructions on other Volkswagen models that also have a similar type of Key Fob.

Why is the VW key fob not working?

If your Volkswagen key FOB doesn't work after replacing the battery, it's possible that it's a technical problem or an operational issue. It may also be due to corrosion. There may be ways to fix this issue yourself, but most people prefer having a professional do it since repairing electrical components can sometimes be dangerous without proper knowledge and many issues are beyond simple fixes anyway. Electrical components can also cause danger if not repaired correctly, which should be done only by professionals who have been trained in such repairs. If the issue persists after the repair, then it's advisable to get in touch with VW to inquire about how to replace the key fob.

What should I do if my Fob won't unlock the car wirelessly?

A broken key can be a major problem if your vehicle won't unlock with the remote or wirelessly. Many factors might cause this issue. The fob might have dead batteries, so you should inspect it for this problem.

The keyless entry system may be faulty in some cases. The antenna can also cause issues with the car's ability to recognize the signal, and if you're not sure about this, then ask your mechanic to inspect it.

If that still doesn't work, then the key fob might be locked in a certain mode and need to be reset back to factory settings for this problem.

In conclusion, if your keyless entry system isn't working, you should take the fob to a professional. If it's not worked on correctly, then you could end up causing more damage which will cost even more money.

However, changing the battery is usually pretty simple and can be done at home without any fancy tools or equipment. Watching for signs of a dead battery can save you from spending more money on replacing the fob or having problems with your car. We hope that this blog post has helped you with the battery replacement of your Volkswagen Key Fob.
