As a content creator for keyfobx.com and an automotive repair specialist, I understand the frustration of dealing with a dead key fob battery. For 2020 Subaru Ascent owners, understanding the factors affecting your key fob battery life and how to optimize it is essential. Let’s dive into the common reasons why your 2020 Subaru Ascent Key Fob Battery might be draining faster than expected and what you can do about it.
Several elements can influence the lifespan of your 2020 Subaru Ascent key fob battery, but two primary factors often stand out: the quality of the battery itself and your usage habits.
Firstly, the quality control of CR2032 coin batteries plays a significant role. Not all CR2032 batteries are created equal. Even from reputable manufacturers, occasional faulty batteries can slip through quality control checks. If you happen to get one of these, it can lead to premature battery drain in your 2020 Subaru Ascent key fob. While it might seem excessive, if you have a battery tester available, it’s worthwhile to quickly check the voltage of a new battery before installing it in your fob. This simple step could save you from potential headaches down the road. It’s also crucial to ensure you know how to manually enter your vehicle using the emergency key and start your Ascent with a potentially dead fob. Familiarize yourself with these procedures now, rather than when you’re unexpectedly faced with a non-functional key fob.
Secondly, your usage habits significantly impact battery life. Are you someone who habitually presses the lock/unlock buttons multiple times as you approach or leave your 2020 Subaru Ascent? This common practice, often driven by habit or impatience, can indeed accelerate battery discharge. Each button press consumes battery power. A simple solution to mitigate this is to leverage the touch-enabled locking and proximity unlocking features available on your 2020 Subaru Ascent. By utilizing these features, you reduce the need for excessive button presses, conserving your key fob battery. For those moments when you might feel the urge to double-check if your car is locked after walking away, consider using the MySubaru/Starlink app to confirm the lock status remotely instead of repeatedly pressing the physical buttons.
Beyond battery quality and usage, there’s also evidence suggesting that proximity between your smart fob and your vehicle can affect battery drain. Anecdotal reports across various car brands indicate that keeping your key fob too close to your 2020 Subaru Ascent when parked can lead to faster battery depletion in both the vehicle’s battery and the key fob battery itself. To prevent this, try to store your key fob further away from your vehicle when you are at home. Alternatively, you might consider purchasing a Faraday cage or a valet box designed to block electromagnetic fields. Storing your key fob in such a container when you’re at home can effectively prevent communication between the fob and the car, allowing both batteries to conserve power and potentially extending their lifespan.
In conclusion, maintaining a healthy battery life for your 2020 Subaru Ascent key fob involves considering battery quality, being mindful of your button usage habits, and managing the proximity of your fob to your vehicle when not in use. By implementing these tips, you can minimize unexpected key fob battery issues and ensure reliable access to your Subaru Ascent.
