How to Tell if Your 2012 Hyundai Elantra Key Fob Battery is Dying
Key fob batteries don’t last forever. Over time, they lose their charge, and the key fob’s signal weakens. Here are some telltale signs that your 2012 Hyundai Elantra key fob battery might be nearing its end:
- Decreased Range: You find yourself having to stand closer to your car to get it to unlock.
- Intermittent Functioning: The key fob works sometimes, but not others, even when you’re within range.
- Multiple Presses Required: You need to press the buttons multiple times to get a response.
- Dashboard Warning Light: Some Hyundai Elantra models might display a warning light on the dashboard when the key fob battery is low.
If you’re experiencing any of these issues, it’s time to consider replacing your key fob battery.
