Signs of a Dying Key Fob Battery

Being aware of the signs of a failing key fob battery can help you avoid the inconvenience of a sudden malfunction. Some common indicators include:

• Decreased range: You might notice that you need to be closer to your Prius for the key fob to work.
• Intermittent operation: The key fob may work sometimes but not others. The car will only respond to your keyfob’s commands intermittently and you may find yourself repeatedly pressing the buttons to activate the central locking or panic system.
• Dim or flickering key fob lights: If your key fob has an indicator light, it might appear dimmer than usual or flicker.
• Difficulty starting the vehicle: In some cases, a low key fob battery can affect the vehicle’s ability to start. It is important to note that this may also be a sign of a problem with the car itself, such as a faulty battery or starter motor. Hence, it’s recommended to consult a qualified mechanic to accurately diagnose the issue.
