Battery Life

The majority of newer cars have keyless entry systems as well as push-button starters. They are controlled by a smart car key replacement cost uk fob that communicates with the car through proximity technology. These systems are powered by a tiny transmitter that is powered by a lithium coin-sized battery. Like any other battery that will eventually require replacement.
