Is your 2014 Hyundai Sonata key fob acting up? Before you shell out cash for a new one, it might just be a simple battery swap. Just like your TV remote, your key fob relies on a tiny battery to send signals to your car. Over time, this battery can drain, leading to a weak signal or even a completely unresponsive key fob.
This guide will walk you through everything you need to know about replacing your 2014 Hyundai Sonata key fob battery, from identifying the right battery type to completing the replacement like a pro.
Signs Your Key Fob Battery Needs Replacing
How can you tell if it’s time for a new key fob battery? Look out for these common signs:
- Decreased Range: You find yourself having to stand closer to your car for the key fob to work.
- Intermittent Functioning: The key fob works sometimes, but not others.
- No Response: Your car simply doesn’t respond to any buttons on the key fob.
- Dashboard Warning: Some Hyundai Sonatas may display a “Key Fob Battery Low” warning on the dashboard.
If any of these sound familiar, chances are your key fob battery is nearing the end of its lifespan.
