Another way that smart keys help keep cars secure is by not sending the same frequency signal over and over again. If a fob transmitted the same signal each time it unlocked a door, or remotely opened the trunk, it could allow thieves who are tech-savvy to connect vehicles to hot wires and take them away. Fortunately, this isn't a problem because smart keys emit an encrypted signal every time the door is opened or the trunk is opened remotely.
