Battery Life
Most newer cars come with keyless entry systems as well as push-button starters. They are controlled by a smart fob that communicates with your car using proximity technology. These systems use a tiny transmitter, powered by a lithium coin-sized battery. Like all batteries it will eventually need replacement.
