15 Interesting Facts About Replacement Key For Smart Car That You Never Known
What is a Smart Key Car Key?
Smart keys are also referred to as proximity keys or key fobs. They function to unlock doors and to start engines without needing to insert physical key. They communicate with one another through radiofrequency signals.

Security
Traditionally keys for cars have been made of metal and used to unlock the ignition. Smart keys eliminate this need. Smart keys have a special chip that sends an electromagnetic signal from the antenna to your car.

Some manufacturers also have an emergency mechanical key blade hidden 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 as well as push-button starting systems that are controlled by a smart key fob that utilizes proximity technology to communicate with the car.
