Subaru Key Fob Battery Replacement: A Quick and Easy Guide

Is your Subaru key fob acting up? Before you run to the dealership, a simple battery replacement might be all you need. This guide will walk you through everything you need to know about replacing your Subaru key fob battery, from identifying the signs of a dying battery to choosing the right replacement and completing the process at home.

How to Tell if Your Subaru Key Fob Battery Needs Replacing

Just like your car battery, your key fob battery has a limited lifespan. Here are some telltale signs that it’s time for a swap:

Decreased range: You find yourself having to stand closer to your car to lock or unlock the doors.
Intermittent functionality: The key fob works sporadically, forcing you to press the buttons multiple times.
Warning light on dashboard: Some Subaru models display a warning light on the dashboard when the key fob battery is low.
No response from the key fob: This is the most obvious sign – your key fob has stopped working entirely.

If you’re experiencing any of these issues, a dead or dying battery is likely the culprit.

What Type of Battery Does a Subaru Key Fob Use?

Most Subaru key fobs use a standard CR2032 battery, a common type of lithium coin battery. You can find these batteries at most hardware stores, auto parts stores, and even online retailers.

Tools You’ll Need

Replacing your Subaru key fob battery is a surprisingly simple DIY project. Here’s what you’ll need:

New CR2032 battery
Small flathead screwdriver or a similar tool for prying open the key fob
Optional: A small container to keep track of the screws

Subaru Key Fob Battery Replacement: Step-by-Step Instructions

The exact procedure might vary slightly depending on the year and model of your Subaru, but the general steps are the same:

Locate the release button or notch on the back of your key fob. This is usually located near the key ring.
Use the flathead screwdriver to carefully pry open the key fob casing. Be gentle to avoid damaging the plastic.
Identify the battery compartment. This is usually a small, separate compartment within the key fob.
Carefully remove the old battery. Take note of the battery’s orientation for installing the new one.
Insert the new CR2032 battery, ensuring it matches the orientation of the old battery.
Snap the key fob casing back together. Make sure it closes securely.
Test the key fob by locking and unlocking your car.

And that’s it! You’ve successfully replaced your Subaru key fob battery.

Tips for a Smooth Battery Replacement

Refer to your Subaru owner’s manual for model-specific instructions. This will provide detailed diagrams and instructions tailored to your vehicle.
Take your time and work carefully to avoid damaging the key fob.
If you’re unsure about any step, it’s best to consult a professional.

Key Fob Still Not Working?

If you’ve replaced the battery and your key fob is still not functioning correctly, there might be another issue at play, such as:

Faulty key fob: Over time, key fobs can experience wear and tear, leading to internal component failure.
Programming issues: Sometimes, a key fob might lose its programming and require reprogramming by a dealer or qualified locksmith.
Other underlying car issues: In rare cases, the problem might lie within your car’s electrical system or keyless entry receiver.
