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

Most newer cars have keyless entry and push button starting systems which are controlled by a key fob that makes use of proximity technology to communicate with the car. These systems rely on a small transmitter powered by a coin-sized lithium battery. Like all batteries, it eventually needs replacement smart key.
