Another way that smart keys can keep vehicles safe is by not sending the same frequency signal over and over again. If a fob broadcasted an individual signal each time it was unlocked or opened an trunk remotely, this allows thieves with a technological advantage to wire cars to take them away. Thankfully, this is not a problem because smart keys emit an encrypted signal each time a door is opened or the trunk is opened remotely.

Smart keys also help prevent cars from being stolen by thieves at fuel stations as well as other parking spots.
