This is similar to how a tablet or smartphone that has a fingerprint scanner integrated functions.

A smart key could also ensure the safety of vehicles by not sending the exact same frequency signal repeatedly. If a fob transmitted the same signal every time it locked a door, or remotely opened the trunk, this could allow tech-savvy thieves to wire vehicles and take them away. Fortunately, this isn't a problem because smart key for car keys emit a distinct encrypted signal each time doors are opened or the trunk is opened remotely.

Smart keys also help prevent cars from being taken away by thieves at fueling stations as well as other parking spots.
