Certain manufacturers also include an emergency mechanical key blade hidden in the key which can be used to open the trunk and start the car should it be needed.
Battery Life

The majority of newer cars come with keyless entry and push button starting systems which are controlled by a key fob that utilizes proximity technology to connect with the car. These systems are powered by a small transmitter which is powered by a coin-sized lithium battery. Like all batteries, it eventually needs replacement.
