Some manufacturers have a mechanical key blade that can be utilized in a situation of emergency to open the trunk or to start the car.
Battery Life
Most newer cars have keyless entry and push button starting systems, controlled by a smart fortwo key replacement key fob that makes use of proximity technology to communicate with the car. These systems are powered by a tiny transmitter that is powered by a lithium coin-sized battery. As with all batteries that eventually requires replacement, this one too will need replacement.
