Experiencing issues with your 2019 Subaru key fob? A common culprit is often a low or dead battery. While it can be a minor inconvenience, understanding the factors that affect your key fob battery life and knowing how to address it can save you from unexpected lockouts. Let’s delve into why your 2019 Subaru key fob battery might need replacing and how to handle it effectively.
Several factors can influence the lifespan of your 2019 Subaru key fob battery. Firstly, the quality control of CR2032 coin batteries, the standard for many key fobs, plays a significant role. Not all CR2032 batteries are manufactured to the same standards. Occasionally, even from reputable brands, a subpar battery might slip through and end up in your key fob, leading to a shorter lifespan than expected. If you’re proactive, using a battery tester to check a new battery before installation can be a worthwhile step, although not always necessary for readily available brands like Energizer or Duracell, which generally offer consistent quality. For those seeking Panasonic batteries, ensure they are genuine when ordering online to avoid counterfeits.
User habits also significantly impact battery drain. Do you frequently press the lock/unlock buttons on your key fob repeatedly as you approach or leave your 2019 Subaru? This habit, while common, accelerates battery consumption. A more efficient approach is to utilize your Subaru’s touch-enabled locking and proximity unlocking features, if equipped. For those moments of uncertainty after walking away from your vehicle, resist the urge to compulsively press the fob buttons; instead, consider using the MySubaru/Starlink app to confirm your vehicle’s lock status remotely.
Another less obvious factor is the proximity of your key fob to your 2019 Subaru when not in use. Evidence suggests that storing your key fob too close to the vehicle can lead to a quicker drain on both the car’s battery and the key fob battery. To prevent this, keep your key fob at a distance from your Subaru when at home, allowing the vehicle to fully enter its “sleep” mode. Alternatively, investing in a Faraday cage or valet box for key fob storage can effectively block signals and prevent unnecessary battery drain caused by constant communication between the fob and the vehicle.
In conclusion, understanding these factors—battery quality, usage habits, and proximity to the vehicle—can help you optimize the battery life of your 2019 Subaru key fob. By being mindful of these elements and adopting recommended practices, you can minimize unexpected battery issues and ensure your key fob remains reliably functional.
