Another way that a smart key keeps cars safe is by not sending the same frequency signal over and over again. If a fob sent the same signal every time it opened the door remotely or opened the trunk, this could allow thieves who are tech-savvy to hotwire vehicles and remove them. Smart keys emit a unique signal every time a trunk or door is opened remotely.

smart fortwo key fob keys also stop the theft of cars by thieves at fueling stations as well as other parking spots. smart key market keys send a low frequency signal that can only be detected by nearby smart keys, not by objects or individuals that are not within the vehicle.
