If a fob sent an alert each time it was unlocked or opened a trunk remotely, it will allow tech-savvy thieves to hotwire cars and eliminate them. Smart keys emit a distinct signal each time a trunk door is opened remotely. Smart keys also help prevent vehicles from being taken by thieves at fueling stations and other parking spaces.
