Some manufacturers also have an key blade that is an emergency mechanical lock in the Key For Smart Car which can be used to open the trunk and begin the car if required.

Battery Life

The majority of newer cars come with keyless entry as well as push-button starting systems operated by a smart key for smart car fob that makes use of proximity technology to communicate with the car. These systems are powered by a small transmitter which is powered by a coin-sized lithium battery. It will eventually need to be replaced, just like any other battery.
