Recognizing a Dying Lexus IS250 Key Fob Battery
Several signs indicate your Lexus IS250 key fob battery is nearing its end. Reduced operating range is a common symptom. You might need to be much closer to your car for the key fob to work. Another telltale sign is weak or inconsistent signals. If your car sometimes unlocks and sometimes doesn’t, a low battery is a likely culprit. Also, look out for flickering or dim indicator lights on the key fob. If the LED light is barely visible when you press a button, it’s definitely time for a replacement.
What if my Lexus IS250 key fob doesn’t work at all? A completely dead battery is the most obvious reason.
