If a fob broadcasted a signal every time it was unlocked or opened a trunk remotely, this would enable tech-savvy thieves hotwire cars and take them away. Thankfully, this is not an issue as smart keys emit a unique encrypted signal every time the door is opened or the trunk is remotely opened.

Smart keys also stop the theft of cars by thieves at fueling stations and other parking lots.
