Introduction

In this guide, I will walk you through the process of changing the battery in your Subaru Impreza key fob. This tutorial covers models from 2015 to 2021. The key fob uses a CR2032 battery, which you can easily purchase online. Follow these simple steps to get your key fob working like new.

Tools and Materials Needed

Before we begin, ensure you have the following:

• CR2032 battery
• Flathead screwdriver

Once you have these items, you’re ready to start.

Step-by-Step Instructions

Step 1: Remove the Internal Key

First, turn the key fob over to the back. Hold down the silver button and remove the internal key. Set the key aside for now.

Step 2: Locate the Keyhole

Look at the area where the key was removed. Above the keyhole, you’ll see a small parallel slot. This is where you will insert your flathead screwdriver.

Step 3: Open the Key Fob

Insert the flathead screwdriver into the slot and twist. You will hear a popping sound, indicating that the back of the key fob is coming off. Continue twisting until the back is completely removed. Set the back cover aside.

Step 4: Remove the Battery

Now, you will see the circuit board and the battery. Hold the circuit board by the sides to avoid touching any delicate components. Use the flathead screwdriver to gently pry the battery out from the plastic housing. The battery will pop out easily.

Step 5: Insert the New Battery

Take your new CR2032 battery. Ensure the positive side (the side with the text) is facing up. Insert the bottom part of the battery first, then click the top into place. If you try to insert the top first, it will not fit correctly.

Step 6: Reassemble the Key Fob

Place the circuit board back into the key fob housing with the battery facing up. Be careful with the rubber components and buttons. Gently click the back cover into place.

Step 7: Test the Key Fob

Reinsert the internal key. Test the key fob by pressing a button to ensure the light turns on. If everything is working correctly, you have successfully replaced the battery.

Conclusion

Replacing the battery in your Subaru Impreza key fob is a simple process that can save you time and money. With just a few tools and a new CR2032 battery, you can have your key fob functioning like new in minutes.
