A dead subaru key fob battery can be a real hassle, leaving you stranded and frustrated. This guide covers everything you need to know about your subaru key fob battery, from identifying signs of a dying battery to replacing it yourself and even some advanced troubleshooting tips.
Different Types of Subaru Key Fob Batteries
Recognizing a Dying Subaru Key Fob Battery
Several tell-tale signs indicate your subaru key fob battery is nearing its end. These include decreased range, intermittent functionality (working sometimes but not others), and the need to be unusually close to your car for the key fob to work. Sometimes, the key fob might not work at all.
“A flickering or dim key fob LED light is another often overlooked indicator of a low battery,” says automotive electronics expert, Michael Stevens, “Pay attention to these subtle clues to avoid unexpected lockouts.”
Common Causes of Subaru Key Fob Battery Drain
Besides the natural lifespan of the battery, factors like extreme temperatures, frequent use, and even accidental button presses in your pocket or purse can contribute to faster battery drain.
