Have you been experiencing frustratingly short battery life from your Subaru key fob? It’s a common concern for Subaru owners, and understanding the reasons behind it can save you from unexpected lockouts. At keyfobx.com, we specialize in automotive key solutions, and we’re here to shed light on why your Key Fob Battery Subaru might be draining faster than expected and what you can do about it.
Several factors can contribute to the lifespan of your key fob battery. Let’s break down the most common culprits:
Battery Quality and Manufacturing
Not all 2032 coin batteries, the standard for most key fobs, are created equal. Quality control can vary between brands and even within the same brand. Occasionally, a faulty battery might slip through, leading to premature failure. If you have a battery tester, it’s a good idea to check a new battery before installing it in your fob. Reputable brands like Energizer or Duracell generally offer better consistency and quality compared to less known brands, especially those sourced online without verification. While Panasonic batteries are often cited for their quality, ensure you’re purchasing genuine ones if ordering online to avoid counterfeits.
Usage Habits and Frequency
Do you find yourself repeatedly pressing the lock/unlock buttons on your fob as you approach or leave your Subaru? This habit, while common, significantly contributes to faster battery depletion. Each button press sends a signal, drawing power from the battery. Subaru vehicles offer convenient alternatives like touch-sensitive door locking and proximity unlocking features. Utilizing these can reduce your reliance on button presses and extend battery life. For those moments of double-checking, the MySubaru/Starlink app provides remote locking/unlocking functionality, further minimizing physical fob usage.
Proximity to Your Subaru
There’s growing evidence suggesting that keeping your key fob too close to your Subaru when parked can also drain the battery, and surprisingly, it can also impact the car’s battery. When the fob is constantly within range of the vehicle, it can maintain a continuous communication, preventing both the fob and the car from fully entering a power-saving “sleep” mode. To mitigate this, store your key fob further away from your Subaru when at home. Alternatively, consider using a Faraday cage or a signal-blocking valet tray to store your fob. This effectively isolates the fob, preventing signal transmission and conserving battery power.
In conclusion, the life of your key fob battery Subaru is influenced by battery quality, how you use your fob, and its proximity to your vehicle. By being mindful of these factors and adopting the suggested tips, you can optimize your key fob battery life and avoid unexpected replacements.
