Some manufacturers have a mechanical key blade that can be used in an emergency situation to open the trunk or to start the vehicle.

Battery Life

Many newer cars have keyless entry systems as well as push-button starters. They are controlled by a smart fob that communicates with the car using proximity technology. These systems use a tiny transmitter, powered by a lithium coin-sized battery. As with all batteries, it eventually needs replacement.
