Battery Life

Many newer cars have keyless entry systems as well as push-button starters. They are controlled by a smart key fob that communicates with the car via proximity technology. These systems use a tiny transmitter that is powered by a lithium coin-sized battery. Like all batteries, it eventually needs replacement.
