Certain manufacturers also include an key blade that is an emergency mechanical lock in the key which can be used to open the trunk and begin the car if required.

Battery Life

The majority of modern cars have keyless entry as well as push-button starting systems operated by a smart forfour key key fob that utilizes proximity technology to connect with the car. These systems are powered by a tiny transmitter which is powered by a coin-sized lithium battery. It will eventually require to be replaced as with any other battery.
