Battery Life

Most newer cars have keyless entry as well as push-button starting systems operated by a smart car keys replacement key fob that utilizes proximity technology to communicate with the car. These systems are powered by a tiny transmitter that is powered by a lithium coin-sized battery. It will eventually require to be replaced, just like any other battery.
