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

Battery Life

Most newer cars have keyless entry as well as push-button starting systems operated by a smart key fob, which uses proximity technology to connect with the car. These systems use a tiny transmitter that is powered by a lithium coin-sized battery. Like any other battery it will eventually need replacement.

These gadgets emit magnetic fields of their own which can interfere with and slow down the fob transmitter.
