If a fob sent the same signal each time it opened doors or remotely opened the trunk, it 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 when doors are opened or the trunk is remotely opened.
