Certain manufacturers also include an emergency mechanical key blade hidden in the key that could be used to open the trunk and start the car should it be needed.

Battery Life

Most newer cars have keyless entry and push-button starting systems which are controlled by a key fob, which uses proximity technology to connect with the car. These systems rely on a small transmitter that is powered by a coin-sized lithium battery. It will eventually require to be replaced as with any other battery.
