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

Smart keys can also help to stop cars from being stolen at gas stations or other parking areas.
