Replacing the key fob battery in your 2015 Subaru STI is a simple task that can save you time and money. This guide will walk you through the process step-by-step, ensuring you can get back on the road with a fully functional key fob. Knowing how to perform this quick replacement yourself avoids the inconvenience of a non-responsive key fob and potential locksmith charges.
Why Replace Your Key Fob Battery Yourself?
A dead key fob battery can leave you stranded and unable to access or start your car. Learning to replace the battery yourself is a valuable skill, offering convenience and cost savings. While dealerships or locksmiths can handle this, a DIY approach empowers you to quickly resolve the issue without relying on others, especially in urgent situations. It’s a straightforward process that requires minimal tools and only a few minutes of your time.
Identifying a Low Key Fob Battery
Several signs indicate a dying key fob battery in your 2015 Subaru STI. Reduced range is a common symptom; you might find yourself needing to be closer to the car for the key fob to work. Another sign is a weaker lock/unlock signal, or the key fob requiring multiple button presses to function. Dimming or flickering key fob indicator lights can also signal a low battery. Finally, if your car’s push-to-start system struggles intermittently, it’s a strong indicator the key fob battery needs replacing.
