Another way that a smart key keeps cars safer is by not sending the same frequency signal over and over again. If a fob broadcasted an individual signal each time it opened or unlocked an trunk remotely, this will allow tech-savvy thieves to connect cars to hotwires and eliminate them. Smart keys emit a unique signal each time a trunk door is opened remotely.

Smart keys also help in preventing theft of cars at gas stations or other parking spots.
