Battery Life

The majority of 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 through proximity technology. These systems are powered by a small transmitter which is powered by a coin-sized lithium battery. Like all batteries that will eventually require replacement.
