Experiencing issues with your 2022 Subaru key fob? A common culprit is a low or dead battery. Fortunately, replacing the battery in your Subaru key fob is a straightforward process you can easily handle yourself. This guide will walk you through the steps and offer tips to ensure your key fob remains powered and reliable.
Recognizing a Low Key Fob Battery
Before your key fob completely stops working, it usually gives warning signs. Being aware of these can help you proactively change the battery and avoid being stranded. Here are common indicators of a weakening key fob battery in your 2022 Subaru:
- Reduced Range: You need to be closer to your Subaru than usual for the key fob to lock or unlock the doors.
- Intermittent Operation: The buttons on your key fob become less responsive, requiring multiple presses.
- Dashboard Warning Light: Some Subaru models display a key fob battery warning light on the dashboard.
- Inability to Start Remotely: If your Subaru has remote start, this feature might become unreliable or stop working altogether.
If you notice any of these signs, it’s time to consider replacing your key fob battery.
Step-by-Step Guide to Replacing Your Subaru Key Fob Battery
Changing the battery in your 2022 Subaru key fob is a simple task requiring minimal tools and time.
Tools You’ll Need
- 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.
- Small Flathead Screwdriver or Key Fob Tool: This is used to gently pry open the key fob case. Many key fobs have a built-in emergency key that can also be used for this purpose.
- Soft Cloth (Optional): To prevent scratches on the key fob casing.
Battery Type
Your 2022 Subaru key fob uses a CR2032 3V lithium coin battery. Ensure you purchase this specific type to guarantee compatibility and optimal performance. Brands like Energizer, Duracell, and Panasonic are reputable choices.
Replacement Steps
- Locate the Emergency Key (if applicable): Most Subaru key fobs have a small emergency mechanical key that slides out. Remove this key.
- Open the Key Fob Casing: Examine your key fob for a small notch or slot. Using your flathead screwdriver or the emergency key, 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 excessive force to avoid damaging the plastic.
- Remove the Old Battery: Once the case is open, you’ll see the CR2032 battery. Note the orientation of the battery (+ side up). Gently pry the old battery out of its housing. A small screwdriver can be helpful here, but be careful not to scratch the battery contacts.
- Insert the New Battery: Place the new CR2032 battery into the housing, ensuring the + (positive) side is facing upwards, matching the orientation of the old battery.
- Close the Key Fob Casing: Carefully align the two halves of the key fob casing and press them firmly together until they snap back into place. Ensure the case is completely closed to protect the internal components.
- Test Your Key Fob: Press the buttons on your key fob to lock and unlock your Subaru to verify that the new battery is working correctly.
Tips to Extend Your Subaru Key Fob Battery Life
While CR2032 batteries are designed to last, certain factors can affect their lifespan. Here are some tips to maximize your Subaru key fob battery life:
- Battery Quality Matters: Opt for reputable brands like Energizer or Duracell. While Panasonic batteries are also good, ensure you are getting genuine ones if ordering online. Lower quality batteries may not last as long or perform as reliably.
- Avoid Excessive Button Pressing: Habitually pressing the lock/unlock buttons repeatedly, especially from a distance, drains the battery faster. Utilize your Subaru’s touch-enabled locking and proximity unlocking features if equipped. For peace of mind after walking away, use the MySubaru/Starlink app to check vehicle status instead of repeatedly pressing the fob buttons.
- Key Fob Proximity to Vehicle: Storing your key fob too close to your Subaru when at home might lead to faster battery drain in both the fob and the vehicle. Keep your key fob at a distance from your car when not in use. Consider using a Faraday bag or box to store your key fob at home. These pouches block signals and prevent communication between the fob and the car, potentially extending battery life.
By following these steps and tips, you can confidently change your 2022 Subaru key fob battery and ensure its reliable operation for years to come. Proactive battery replacement and mindful usage habits will help you avoid key fob issues and keep you on the road.
