Introduction

If you own a Subaru STI from the years 2016 to 2020, you may encounter the need to replace the battery in your key fob. This process is straightforward and can be done at home with minimal tools. In this guide, I will walk you through each step to ensure your key fob is back in working order.

What You Will Need

Before you start, gather the necessary tools and materials. You will need a flathead screwdriver and a new CR2032 battery. If you don’t have a CR2032 battery, you can easily buy one on Amazon.

Removing the Internal Key

Start by flipping your key fob over to the back. Locate a small silver button. Hold down this button and pull out the internal key. Set the key aside for now.

Opening the Key Fob

With the internal key removed, look for the keyhole and a smaller indentation above it. Insert your flathead screwdriver into this indentation. Hold the key fob loosely and twist the screwdriver. This will start to separate the back piece of plastic.

Continue to twist or use your fingers to pull the back piece apart. Set the back piece aside.

Removing the Old Battery

Inside the key fob, you will see a small component held in place by a rubber piece. Carefully lift out this component, being cautious not to dislodge the buttons held by the rubber.

Hold the component by the sides to avoid touching delicate parts. Insert the corner of your flathead screwdriver between the battery and the black plastic behind it. Apply gentle pressure to pry the battery out.

Inserting the New Battery

Take your new CR2032 battery and slide it into the compartment, starting with the lower part. Ensure it clicks into place by pressing the top of the battery down.

If you don’t have a CR2032 battery yet, you can purchase one here.

Reassembling the Key Fob

Pick up the back piece of plastic and align it with the front part of the key fob. Slowly fold the pieces together until they click back into place.

Reinsert the internal key and check if the key fob light comes on, indicating the battery has power.

Conclusion

Replacing the battery in your Subaru STI key fob is a simple task that can save you time and money. With just a flathead screwdriver and a new CR2032 battery, you can easily get your key fob working again.
