Signs Your Key Fob Battery Needs Replacing

• Decreased Range: If you notice that your key fob only works when you're closer to your car than usual, this could indicate a weakening battery.
• Intermittent Functionality: If your key fob works sporadically, only functioning at certain times or not at all, it's likely that your battery is dying.

• Warning Light: Some Hyundai and Toyota models have a warning light on the dashboard that illuminates when the key fob battery is low.
• Car Doesn't Respond: If your car doesn't respond at all when you try to unlock it, start it, or use any other functions of the key fob, your battery may be dead.

Now, let's delve into the heart of our key fobs: the batteries. You might wonder, what kind of battery powers my Hyundai or Toyota key fob?
