Is your Subaru key fob starting to feel unresponsive? You might be facing a dead or dying battery. Don’t worry, replacing the battery in your Subaru key fob is a straightforward process you can easily do yourself. This guide will walk you through the steps to change your Subaru key fob battery, ensuring you’re never caught off guard by a dead remote.
Recognizing When to Replace Your Key Fob Battery
Before we dive into the how-to, let’s identify the signs that indicate your Subaru key fob battery needs replacing:
- Reduced Range: You need to be closer to your Subaru than usual for the key fob to lock or unlock the doors.
- Inconsistent Operation: Sometimes the buttons work, and sometimes they don’t, requiring multiple presses.
- Dashboard Warning Light: Some Subaru models display a low key fob battery warning light on the dashboard.
- Key Fob Not Working at All: The most obvious sign – your key fob completely fails to lock/unlock doors or start the vehicle remotely.
If you’re experiencing any of these issues, it’s time to consider a battery replacement. Luckily, it’s a quick and inexpensive fix.
Gathering the Necessary Tools
You won’t need many tools for this task. Here’s what you’ll likely need:
- A new CR2032 battery: This is the standard coin battery for most Subaru key fobs. You can find these at most drugstores, supermarkets, and online retailers. Brands like Energizer or Duracell are reliable choices.
- A small flathead screwdriver or prying tool: This will help you open the key fob case. A small eyeglass screwdriver or even a butter knife can work carefully.
- A soft cloth (optional): To protect the key fob casing from scratches.

Step-by-Step Guide to Changing Your Subaru Key Fob Battery
Now, let’s get to the actual battery replacement. Follow these steps carefully:
-
Locate the Notch or Seam: Examine your Subaru key fob closely. You’ll find a small notch or seam, usually on the side or bottom of the fob. This is where you’ll need to pry it open.
-
Use Your Tool to Open the Fob: Gently insert your flathead screwdriver or prying tool into the notch or seam. Twist or lever the tool carefully to separate the two halves of the key fob casing. Avoid using excessive force to prevent damage. If you are having trouble, check for a small screw that may be holding the case together on some models.
-
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.
-
Remove the Old Battery: Note the orientation of the old battery (usually positive side up). Use your fingertip or the tip of your tool to gently pry the old battery out of its holder.
-
Install the New Battery: Place the new CR2032 battery into the holder, ensuring the positive (+) side is facing the correct direction (usually upwards, matching the orientation of the old battery). Push it gently until it clicks into place.
-
Reassemble the Key Fob: Carefully align the two halves of the key fob casing and press them firmly back together until they snap closed. Ensure there are no gaps and the case is securely sealed.
-
Test Your Key Fob: Press the buttons on your key fob to test if it’s working correctly. The doors should lock and unlock, and the panic button should function.
Tips to Prolong Your Subaru Key Fob Battery Life
While changing the battery is easy, you can also take steps to extend its lifespan:
- Battery Quality Matters: Opt for reputable brands like Energizer or Duracell for your replacement batteries. Higher quality batteries tend to last longer.
- Avoid Excessive Button Pressing: Refrain from repeatedly pressing the lock/unlock buttons unnecessarily, especially when you are already within range of your vehicle. This can drain the battery faster.
- Utilize Touch and Proximity Features: If your Subaru has touch-sensitive door handles or proximity unlocking, use these features instead of always relying on button presses.
- Store Your Key Fob Away from the Vehicle: Keeping your key fob too close to your Subaru for extended periods might cause battery drain in both the fob and the car. Store it at a reasonable distance when at home. Consider using a Faraday box to block signals if you are concerned about signal theft, which can also inadvertently drain the battery if the fob and car are constantly communicating.
Conclusion
Changing your Subaru key fob battery is a simple maintenance task that any car owner can accomplish. By following these steps, you can quickly restore your key fob’s functionality and avoid the inconvenience of a dead battery. Keeping these tips in mind will also help you maximize the lifespan of your key fob battery, ensuring reliable access to your Subaru for years to come.
