Why Your Key Fob Might Need a New Battery
A failing key fob battery can manifest in several ways. You might notice a decreased range, meaning you have to be closer to your car for the key fob to work. The locks might respond intermittently or not at all. Sometimes, the key fob’s LED light might appear dim or flicker. If you’re experiencing any of these issues, a dead battery is likely the culprit.
