Smart locks allow you to quickly enter your home using the LittleBird app or the integrated keypad. To function properly, your smart locks require power provided by a set of four AA batteries. As the battery levels drop to critical levels, you may begin to notice that the lock is no longer responding to commands from the LittleBird app, or the keypad stops functioning.
