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

Battery Life

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