This is similar to how a phone or tablet equipped with an embedded fingerprint scanner functions.

A Smart Fortwo key fob key could also ensure the safety of vehicles by not sending the exact frequency signal repeatedly. If a fob sent the same signal each time it opened a door or remotely opened the trunk, this could allow tech-savvy thieves to hotwire vehicles and remove them. Smart keys emit a different signal each time a trunk or door is opened remotely.

Smart keys also help prevent the theft of cars by thieves at fueling stations and other parking spaces.
