Experiencing issues with your 2020 Subaru Ascent key fob? One common culprit is the key fob battery. While it depends on several factors, understanding these can help you maximize battery life and avoid unexpected surprises. Let’s delve into the primary reasons behind 2020 Ascent key fob battery drain and what you can do about it.
One significant factor is the quality control of the CR2032 coin battery itself. Not all batteries are created equal. Even from reputable brands, a faulty battery can occasionally slip through. If you own a battery tester, it’s a worthwhile step to quickly check a new battery before installing it in your fob. This simple check can save you potential headaches down the road. It’s also wise to familiarize yourself with your emergency key to ensure it works correctly, providing a backup entry method should your fob battery fail unexpectedly. Starting your Ascent with a dead fob is possible, but it can be a stressful experience if you’re unprepared. For reliable replacement batteries, trusted brands like Energizer or Duracell are readily available and offer consistent quality. If you prefer Panasonic batteries, ensure they are genuine when ordering online.
User habits also play a crucial role in key fob battery longevity. Do you frequently press the lock and unlock buttons as you approach or leave your vehicle? This habit, while common, can significantly accelerate battery discharge. A more efficient alternative is to utilize the touch-enabled locking and proximity unlocking features of your Ascent. If you find yourself compulsively checking if your car is locked after walking away, consider using the MySubaru/Starlink app to confirm, rather than repeatedly pressing the fob buttons.
Lastly, the proximity of your key fob to your vehicle can impact battery life for both devices. Evidence suggests that storing your smart fob too close to your Ascent can lead to battery drain in both the fob and the car. To prevent this, maintain sufficient distance between your fob and vehicle when at home. Alternatively, consider using a Faraday cage or a valet box to store your key fob. These devices block electronic signals, preventing communication between the fob and the car when not in use, thus conserving battery power.
By understanding these factors – battery quality, usage habits, and proximity – you can better manage your 2020 Ascent key fob battery life and minimize unexpected issues.
