Battery Life

Most newer cars come with keyless entry systems as well as push-button starters. They are controlled by a smart fob which communicates with the car via proximity technology. These systems utilize a tiny transmitter, powered by a coin-sized lithium battery. As with all batteries it will eventually need replacement.
