Introduction

Replacing the battery in your Subaru Outback key fob is a straightforward task that you can easily do at home. In this guide, I’ll walk you through the steps to change the battery yourself. All you’ll need is a CR2032 coin battery and a flathead screwdriver.

Required Tools and Materials

Before we get started, gather the necessary tools and materials:

• CR2032 coin battery
• Flathead screwdriver

These items are essential for a smooth and successful battery replacement process.

Step-by-Step Battery Replacement Guide

Follow these steps to replace the battery in your Subaru Outback key fob:

Step 1: Remove the Internal Key

First, turn the key fob over and locate the silver button. Hold down the silver button to release the internal key. Remove the key and set it aside for now.

Step 2: Open the Key Fob

With the internal key removed, focus on the key fob. Look for a small slot or indentation near the keyhole. Insert your flathead screwdriver into this slot and gently twist. This action will create a small separation, allowing you to open the key fob.

Continue twisting the screwdriver until the back of the key fob pops off. Be careful not to apply too much force to avoid damaging the plastic casing.

Step 3: Remove the Circuit Board and Battery

Once the key fob is open, you’ll see the circuit board and the battery. Hold the circuit board by the sides to avoid touching any sensitive components. Carefully lift it out of the key fob.

Locate the battery, which is held in place by a small plastic clip. Insert the corner of your flathead screwdriver between the battery and the clip. Apply gradual pressure to lift the battery out of its compartment.

Step 4: Insert the New Battery

Take your new CR2032 battery and ensure the positive side (marked with a “+”) is facing up. Slide the battery into the compartment, starting from the bottom and pressing it into place at the top.

Step 5: Reassemble the Key Fob

Now, carefully place the circuit board back into the key fob. Make sure the battery icon on the circuit board aligns with the battery compartment. Hold the two halves of the key fob together and press them gently until they click back into place.

Reinsert the internal key, and test the key fob to ensure it’s working correctly. The indicator light should come on, confirming that the battery is properly installed.
