Another way that smart keys can keep cars safe is by not sending the same frequency signal repeatedly again. If a fob broadcasted the same signal each time it opened a door, or remotely opened the trunk, it would permit thieves with a tech-savvy mindset to connect vehicles to hot wires and remove them. Smart keys emit a different signal every time a trunk or door is opened remotely.

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

This is what's known as relay, and it's used by hackers to steal cars from fueling stations as well as parking lots.

Most smart car key recoding key systems do have a backup system to start and open the vehicle in the case of the battery being dead.
