How to Replace the Battery in a Subaru WRX Key Fob (2016 – 2020)

Introduction

Replacing the battery in your Subaru WRX key fob is a straightforward process that can save you time and money. This guide will walk you through the steps to change the internal battery, ensuring your key fob functions correctly.

Materials Needed

Before you begin, gather the following materials:

• CR2032 coin battery
• Flathead screwdriver

You can purchase the CR2032 battery from Amazon.com for a few dollars. This specific battery is compatible with Subaru WRX key fobs from 2016 to 2020.

Step-by-Step Guide

Step 1: Remove the Internal Key

First, flip the key fob over to the back. Hold down the silver button and remove the internal key. If your key is missing, you can still proceed by pressing the button and setting the key aside.

Step 2: Open the Key Fob

Next, locate the smaller hole above the keyhole. Insert your flathead screwdriver into this hole. Hold the device loosely and twist the screwdriver until you hear a click. This sound indicates that the back piece of plastic is starting to come off.

Once you hear the click, use your fingers to pull off the back piece of plastic. If needed, you can continue twisting the screwdriver to create a larger opening. Set the back piece aside.

Step 3: Remove the Battery Holder

Carefully remove the component that holds the battery. Do not flip this piece over, as the buttons may fall out along with the rubber piece. Hold this component right side up and set it down gently.

Step 4: Extract the Old Battery

Hold the battery holder by the sides to avoid touching the circuit board. Use the same flathead screwdriver to remove the old battery. Insert the screwdriver between the battery and the black plastic piece, then twist gently to pop the battery out.

Take your time and be careful not to break anything. The battery should come out smoothly. If you need a new battery, you can purchase one from Amazon.com.

Step 5: Insert the New Battery

When inserting the new CR2032 battery, ensure the positive side with the text faces up. Slide the battery into place and click the top in. The battery should sit securely in the holder.

Step 6: Reassemble the Key Fob

Pick up the back side of the key fob and set it on top of the rubber piece. Ensure the buttons do not fall out. Then, take the back piece of plastic and set it on top. Click all the pieces together.

Test the key fob by pressing the buttons to ensure the light comes on. This confirms that the battery is installed correctly and the key fob is functioning as expected.

Conclusion

Changing the battery in your Subaru WRX key fob is a simple process that can be completed in a few minutes. By following these steps, you can ensure your key fob remains in good working condition, saving you the hassle of visiting a dealership.
