Certain manufacturers also include an emergency mechanical key blade in the key that can be used to open the trunk and start the car should it be needed.
Battery Life
Most newer cars have keyless entry and push button starting systems, controlled by a smart key fob that makes use of proximity technology to connect with the car. These systems rely on a small transmitter powered by a coin-sized lithium battery. Like any other battery that eventually requires replacement, this one too will need replacement.
