Decreased Range: You find yourself having to stand closer to your car to lock or unlock the doors.
Intermittent Functioning: The key fob works sometimes, but not others, even when you’re within a reasonable distance.
Dim or No Lights: The LED light on your key fob is fainter than usual or doesn’t light up at all when you press a button.
Slow Response Time: The car takes longer to respond to signals from your key fob.

If you’re experiencing any of these issues, it’s time to consider replacing your key fob battery.
