Some manufacturers have a motorized key blade that can be utilized in a situation of emergency to open the trunk or to start the car.

Battery Life

The majority of newer cars come with keyless entry and push button starting systems which are controlled by a key fob that utilizes proximity technology to connect with the car. These systems use a tiny transmitter, powered by a lithium coin-sized battery. Like any other battery, it eventually needs replacement smart car key.
