Battery Life

The majority of modern cars have keyless entry systems and push-button starters. These are controlled by a smart fob that communicates with the car using proximity technology. These systems are powered by a tiny transmitter that is powered by a coin-sized lithium battery. As with all batteries that will eventually require replacement.
