A smart key can also help to protect vehicles by not sending the exact frequency signal repeatedly. If a fob broadcasted the same signal every time it opened doors or remotely opened the trunk, this would permit thieves with a tech-savvy mindset to use hotwires to remove them. Fortunately, this isn't an issue because smart keys emit a distinct encrypted signal every time doors are opened or the trunk is opened remotely.
