Is your Subaru key fob starting to feel a little unresponsive? Maybe you need to press the buttons harder, or maybe it’s just not working from as far away as it used to. These are classic signs that the battery in your key fob is getting weak and it might be time for a replacement. Don’t worry, replacing the battery in a Subaru key fob is a simple task you can easily do yourself in just a few minutes. This guide will walk you through the process step-by-step, ensuring you can get your key fob working like new again.
What You’ll Need
Before you begin, gather these simple items:
- A new CR2032 battery: This is the standard coin battery size 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 help you open the key fob case. A small coin can also work in a pinch.
- A soft cloth (optional): To protect the key fob from scratches.
Step-by-Step Guide to Replacing Your Subaru Key Fob Battery
Follow these easy steps to replace your Subaru key fob battery:
Step 1: Open the Key Fob
Locate the small notch or opening on your Subaru key fob. This is usually on the side or bottom of the fob. Using your flathead screwdriver or pry tool (or coin), gently insert it into the notch and twist or pry to separate the two halves of the key fob casing. Be careful not to apply too much force to avoid damaging the plastic. You can wrap the tip of your screwdriver with a soft cloth to minimize the risk of scratches.
Step 2: Remove the Old Battery
Once the key fob is open, you’ll see the battery. It’s usually held in place by small clips or pressure. Note the orientation of the battery (which side is facing up) before removing it – usually the positive (+) side faces upwards. Gently pry the old battery out of its compartment. You can use your fingertip or the edge of your tool, being careful not to damage the battery compartment or any internal components.
Step 3: Insert the New Battery
Take your new CR2032 battery and insert it into the battery compartment, making sure the orientation is the same as the old battery you just removed (positive side up). Push down gently until the battery is securely in place and held by the clips.
Step 4: Close the Key Fob
Carefully align the two halves of the key fob casing back together. Press them firmly until they snap securely closed. Ensure there are no gaps and the case is fully sealed.
Step 5: Test Your Key Fob
Now it’s time to test your newly powered key fob! Try locking and unlocking your Subaru from a distance to ensure the new battery is working correctly. If everything works as expected, you’ve successfully replaced your Subaru key fob battery.
Tips to Extend Your Subaru Key Fob Battery Life
While replacing the battery is straightforward, you can also take steps to prolong the life of your key fob battery:
- Battery Quality Matters: Using high-quality batteries from reputable brands like Energizer or Duracell can sometimes offer better longevity and performance compared to cheaper, generic brands. While a battery tester can help check battery quality, these brands are generally reliable.
- Avoid Excessive Button Pressing: Habitually pressing the lock/unlock buttons repeatedly, especially when you are already close to the vehicle, can drain the battery faster. If your Subaru has touch-sensitive door handles or proximity unlocking, utilizing these features can reduce unnecessary battery usage.
- Key Fob Proximity: Storing your key fob too close to your vehicle when at home might also contribute to faster battery drain. Some evidence suggests that constant communication between the fob and the car, even when idle, can consume battery power in both devices. Try to store your key fob further away from your vehicle when you are not using it, or consider using a Faraday box to block signals if you suspect this might be an issue.
Replacing your Subaru key fob battery is a simple maintenance task that can save you time and potential inconvenience. By following these steps and adopting good battery-saving habits, you can keep your key fob working reliably for years to come. Remember to also check your physical emergency key periodically to ensure it works correctly, just in case you ever encounter a situation where the key fob battery is completely dead.
