Another way that smart keys can keep vehicles safe is by not sending the same frequency signal repeatedly again. If a smart fortwo key replacement key sends an alert each time it opened or unlocked an trunk remotely, this would enable tech-savvy thieves hotwire cars and drive them away. Smart keys emit a different signal each time a trunk or door is opened remotely.
