Another way that smart car key supplier keys keep cars safe is by not sending the same frequency signal over and over again. If a fob sent an individual signal each time it unlocked or opened the trunk remotely, this will allow tech-savvy thieves to use hotwires to connect cars and remove them. Smart keys emit a distinct signal each time a trunk door is opened remotely.

Smart keys also prevent cars from being stolen by thieves at fueling stations and other parking areas.
