Certain manufacturers offer a mechanical key blade that can be used in an emergency situation 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, controlled by a smart key fob that utilizes proximity technology to connect with the car. These systems are powered by a small transmitter which is powered by a coin-sized lithium battery. Like all batteries that eventually requires replacement, this one too will need replacement.
