2021 Subaru Forester Change Key Fob Battery

If you’re experiencing issues with your 2021 Subaru Forester key fob, a dead battery might be the culprit. Don’t worry, changing the key fob battery is a quick and easy process you can do yourself at home, saving you a trip to the dealership. This guide will walk you through the steps to replace your key fob battery and get you back on the road with minimal hassle.

Understanding Your Key Fob

Before we dive into the replacement process, let’s familiarize ourselves with the Subaru Forester key fob. This seemingly simple device houses essential components that allow you to lock, unlock, and even start your vehicle remotely. Understanding its features and potential issues can save you time and frustration.

The key fob communicates with your Subaru through radio frequencies, and like any electronic device, it relies on a battery for power. Over time, this battery will naturally drain and eventually die, affecting the fob’s range and responsiveness.

Common Signs of a Dying Key Fob Battery

How do you know if it’s time to replace your key fob battery? Here are some common signs to watch out for:

Decreased Range: You find yourself needing to stand closer to your car for the key fob to work.
Intermittent Functioning: The fob works sporadically, sometimes requiring multiple presses of a button.
Warning Lights or Messages: Your Subaru’s dashboard might display a “Key Fob Battery Low” warning message.

If you’re experiencing any of these symptoms, it’s highly likely that your key fob battery is nearing its end and needs replacement.

What You Need to Change Your 2021 Subaru Forester Key Fob Battery

Replacing your Subaru Forester key fob battery is a straightforward task. Here’s what you’ll need:

A new CR2032 battery: These are readily available at most hardware stores, auto parts stores, and online retailers.
A small flathead screwdriver: This will be used to pry open the key fob casing.

Step-by-Step Guide to Change the Battery

Now, let’s walk through the replacement process step-by-step:

Locate the key slot on the back of your key fob. This is a small, recessed button.
Insert the flathead screwdriver into the key slot and gently pry open the key fob casing. Be careful not to damage the plastic.
Carefully separate the two halves of the key fob. You should now see the battery inside.
Gently pry out the old battery from its slot. Avoid touching the battery contacts on the fob.
Insert the new CR2032 battery into the slot, ensuring the positive (+) side is facing up.
Align the two halves of the key fob and press them back together until you hear a click. This indicates the casing is securely closed.

Testing Your New Key Fob Battery

Once you’ve replaced the battery, it’s essential to ensure everything is working correctly. Test all the key fob functions, including locking and unlocking the doors and starting the engine. If everything works as expected, you’ve successfully replaced your Subaru Forester’s key fob battery.

Still Having Trouble?

While replacing the key fob battery is a simple process, there might be instances where the issue persists. This could be due to other factors, such as a faulty key fob or a problem with your vehicle’s receiver. If you’ve replaced the battery and are still experiencing problems with your key fob, it’s best to consult a qualified automotive locksmith or your Subaru dealership for further diagnosis and assistance.
