Is your Subaru key fob starting to feel sluggish, or worse, completely unresponsive? Before you panic, the solution might be as simple as replacing the battery. Like any battery-powered device, the battery in your Subaru key fob will eventually need replacing. Understanding why this happens and knowing how to easily replace it yourself can save you time and unnecessary dealership visits. This guide, brought to you by the auto experts at keyfobx.com, will walk you through everything you need to know about replacing your Subaru key fob battery and keeping your remote working smoothly.
Understanding Your Subaru Key Fob Battery
Most Subaru key fobs rely on a common and readily available CR2032 coin battery. These batteries are known for their longevity, but several factors can influence how long they actually last in your key fob.
Firstly, the quality of the battery itself plays a significant role. Not all CR2032 batteries are created equal. Just like any product, manufacturing quality can vary. Occasionally, a battery might be faulty right out of the package. Opting for reputable brands like Energizer or Duracell generally ensures better consistency and lifespan compared to less known brands. While Panasonic batteries are also a good choice, ensure you are purchasing genuine ones, especially when ordering online. If you have a battery tester, it’s a worthwhile step to quickly check a new battery before installing it in your fob to rule out a faulty battery from the start.

Secondly, your usage habits significantly impact battery drain. Do you find yourself repeatedly pressing the lock and unlock buttons as you approach or leave your Subaru? This common habit, often driven by impatience or a desire for confirmation, actually uses more battery power than necessary. Modern Subaru vehicles offer touch-sensitive locking and proximity unlocking features specifically designed to minimize battery usage. Utilizing these features can significantly extend your key fob battery life. For those moments of doubt after walking away from your car, instead of pressing the fob buttons again, consider using the MySubaru/Starlink app to check your vehicle’s lock status.
Lastly, proximity to the vehicle can also affect battery life. There’s growing evidence suggesting that keeping your key fob too close to your Subaru when at home can lead to faster battery drainage in both the fob and the car itself. To prevent this, store your key fob away from your vehicle when you’re at home. Alternatively, consider using a Faraday cage or a signal-blocking valet tray to store your fob, which effectively blocks communication between the fob and the car when not in use.
Step-by-Step Guide to Replacing Your Subaru Key Fob Battery
Replacing your Subaru key fob battery is a straightforward process you can typically do yourself in just a few minutes. Here’s a general guide:
Tools You’ll Need:
- A new CR2032 battery
- A small flathead screwdriver or a similar thin tool (like a key or a plastic trim removal tool)
- A soft cloth to protect surfaces (optional)
Steps to Replace the Battery:
- Locate the notch or seam on your key fob: Examine your Subaru key fob closely. You’ll usually find a small notch or seam that indicates where you can open the fob.
- Carefully open the key fob: Using your flathead screwdriver or thin tool, gently pry open the key fob at the notch or seam. Be careful not to force it, as you could damage the plastic casing. A soft cloth can be used to protect the fob from scratches during this step.
- Identify the battery: Once open, you’ll see the CR2032 battery. Note the orientation of the battery (positive side up or down) before removing it.
- Remove the old battery: Gently pry out the old battery. You might be able to use your fingertip or the flathead screwdriver to carefully lift it out.
- Insert the new battery: Place the new CR2032 battery into the compartment, ensuring it’s in the correct orientation (matching how the old battery was placed). You should hear or feel it click into place.
- Close the key fob: Carefully snap the two halves of the key fob back together until they are securely closed.
- Test your key fob: Test the buttons on your key fob to ensure it’s working correctly. The indicator light on the fob should illuminate when you press a button.
Tips to Extend Your Subaru Key Fob Battery Life
Beyond just replacing the battery, you can adopt a few habits to prolong the life of your Subaru key fob battery:
- Use touch and proximity features: Utilize your Subaru’s touch-sensitive door handles and proximity unlocking to minimize button presses.
- Avoid excessive button pressing: Be mindful of how often and how many times you press the lock/unlock buttons.
- Store your fob away from the car: When at home, keep your key fob at a distance from your Subaru to prevent constant communication and battery drain.
- Invest in quality batteries: Choose reputable brands like Energizer or Duracell for reliable performance and longevity.
By understanding the factors that affect your Subaru key fob battery life and following these simple replacement steps and tips, you can keep your key fob functioning optimally and avoid the inconvenience of a dead remote. Replacing your Subaru key fob battery is a simple DIY task that empowers you to stay in control of your vehicle’s access and security.
