Battery Life

Most newer cars come with keyless entry systems and push-button starters. These are controlled by a smart device that communicates with the car through proximity technology. These systems use a tiny transmitter that is powered by a coin-sized lithium battery. It will eventually need to be replaced like any other battery.
