Certain manufacturers offer a mechanical key blade that can be used in an emergency situation to open the trunk or to start the vehicle.

Battery Life

The majority of modern cars have keyless entry systems and push-button starters. They are controlled by a smart fob that communicates with the car using proximity technology. These systems are powered by a tiny transmitter which is powered by a lithium coin-sized battery. It will eventually need to be replaced just like any other battery.
