This is similar to the way a smartphone or tablet with an embedded fingerprint scanner works.

A smart key can also make cars safer by not sending the exact same frequency signal repeatedly. If a smart key sends a signal every time it was unlocked or opened a trunk remotely, this will allow tech-savvy thieves to use hotwires to connect cars and drive them away. Smart keys emit a unique signal each time a trunk door is opened remotely.

Smart keys also protect cars from being taken away by thieves at fuel stations and other parking spaces.
