Experiencing a low battery warning on your Subaru key fob can be frustrating. While it might seem like a minor inconvenience, a dead key fob battery can prevent you from remotely accessing your vehicle and even starting it in some cases. As your trusted automotive repair expert from keyfobprog.com, let’s explore the common reasons behind these warnings and how to address them effectively.
One of the primary factors influencing your Subaru key fob battery life is the quality control during the manufacturing of the CR2032 coin battery itself. Not all batteries are created equal. Even from reputable brands, occasionally a faulty battery might slip through. If you own a battery tester, it’s a worthwhile step to quickly check the battery’s voltage before installing it in your fob. This simple check can save you from potential headaches down the road. It’s also crucial to familiarize yourself with your Subaru’s emergency key and ensure it mechanically unlocks your door. Knowing how to manually enter and start your Subaru with a fob that’s not transmitting is essential, especially when faced with an unexpected low battery situation.
Another often overlooked factor is user behavior. Do you find yourself repeatedly pressing the lock and unlock buttons as you approach or leave your Subaru? This habit, driven by impatience or a desire for reassurance, significantly drains the key fob battery faster. A smarter solution is to utilize your Subaru’s touch-sensitive locking and proximity unlocking features. These systems are designed to minimize battery usage. If you still feel the urge to double-check after walking away, consider using the MySubaru or Starlink app to remotely confirm your vehicle’s lock status, instead of repeatedly pressing the physical buttons.
Furthermore, anecdotal evidence across various car brands, including Subaru, suggests that storing your smart key fob too close to your vehicle can lead to faster battery depletion in both the fob and the car. When the key fob is in close proximity, it can maintain constant communication with the vehicle, preventing both from entering a full “sleep” mode. To prevent this, store your key fob away from your Subaru when you are at home. Alternatively, investing in a Faraday cage or a signal-blocking valet box can effectively isolate your key fob and prevent unnecessary battery drain caused by continuous signal transmission.
In conclusion, understanding these factors can significantly improve your Subaru key fob battery life and help you avoid unexpected low battery warnings. By choosing quality batteries, adjusting usage habits, and being mindful of key fob storage, you can ensure your key fob remains reliable and functional for longer.
