Another way that smart keys keep vehicles safe is by not sending the same frequency signal repeatedly again. If a fob transmitted the same signal each time it unlocked a door, or remotely opened the trunk, it would allow tech-savvy thieves to hotwire vehicles and make them disappear. Smart keys emit a different signal every time a trunk or door is opened remotely.
Smart keys also help prevent vehicles from being taken by thieves at fueling stations and other parking spaces. Smart keys emit a low frequency signal that can only be detected by nearby smart keys, not by any other objects that are not within the vehicle.
