We’ll also cover some tips to extend your key fob battery life and ensure you’re never caught off guard.
What You’ll Need
Changing your Subaru key fob battery is a straightforward task that requires minimal tools. Here’s what you’ll need:
- A new CR2032 battery: This is the standard battery type for most Subaru key fobs. You can find these at most drugstores, supermarkets, and online retailers.
- A small flathead screwdriver or a thin pry tool: This will be used to gently open the key fob case. A butter knife or even a guitar pick can also work in a pinch.
- A soft cloth (optional): To protect the key fob casing from scratches.
Step-by-Step Guide to Changing Your Subaru Key Fob Battery
Follow these simple steps to replace your Subaru key fob battery:
-
Locate the notch or seam on your key fob: Most Subaru key fobs have a small notch or seam running along the edge. This is where you’ll insert your tool to open the case.
-
Carefully pry open the key fob: Insert the flathead screwdriver or pry tool into the notch or seam. Gently twist or pry to separate the two halves of the key fob case. Be patient and avoid using excessive force, as you could damage the casing. Using a soft cloth around the tip of your tool can help prevent scratches.
-
Identify the battery location: Once the key fob is open, you’ll see the circuit board and the battery. The CR2032 battery is usually held in place by small clips or a bracket.
-
Remove the old battery: Carefully note the orientation of the old battery (+ side up or down) before removing it. Use your fingertip or the tip of your tool to gently pry the old battery out of its housing.
-
Insert the new CR2032 battery: Place the new CR2032 battery into the battery compartment, ensuring it’s in the correct orientation (matching the orientation of the old battery). You should feel it snap into place.
-
Reassemble the key fob: Carefully align the two halves of the key fob case and press them firmly together until they snap back into place. Ensure there are no gaps and the case is securely closed.
-
Test your key fob: Press the buttons on your key fob to test if it’s working correctly. The doors should lock/unlock, and the panic button should function.

Tips to Extend Your Subaru Key Fob Battery Life
While changing the battery is easy, you can prolong the life of your key fob battery with these helpful tips:
-
Use quality batteries: Not all CR2032 batteries are created equal. Opt for reputable brands like Energizer or Duracell for better quality and consistency. While Panasonic batteries are also a good choice, ensure they are genuine if ordering online to avoid counterfeits.
-
Avoid excessive button pressing: Resist the urge to repeatedly press the lock/unlock buttons, especially when you are already within range of your vehicle. Each press drains the battery. Utilize touch-enabled locking and proximity unlocking features if your Subaru is equipped with them. For those moments when you’re unsure if you locked the car, use the MySubaru/Starlink app to check and lock remotely instead of excessive button pressing.
-
Keep your key fob away from your Subaru when at home: Proximity to your vehicle can cause constant communication between the fob and the car, leading to faster battery drain in both the fob and the car itself. Store your key fob away from your vehicle when you are at home. Consider using a Faraday cage or a metal box to store your fob, which blocks signals and prevents unnecessary battery drain if you park close to your house. This is especially relevant for modern key fobs that are constantly communicating with the vehicle.
Don’t Forget Your Mechanical Key
While a dead key fob battery can be inconvenient, remember that your Subaru key fob also contains a mechanical emergency key. It’s crucial to ensure this key works properly. Test your mechanical key to manually unlock your door to avoid being locked out in an emergency.
By following these steps and tips, you can confidently change your Subaru key fob battery and maintain its longevity, ensuring you’re always ready to hit the road.
