Certain manufacturers have a mechanical key blade that can be used in an emergency to open the trunk or to start the vehicle.
Battery Life
The majority of newer cars come with keyless entry as well as push-button starting systems operated by a smart key fob, which uses proximity technology to connect with the car.
