If a fob sent the same signal each time it unlocked a door, or remotely opened the trunk, it would allow tech-savvy thieves to use hotwires to remove them. Thankfully, this is not an issue because smart keys emit a different encrypted signal every time doors are opened or the trunk is opened remotely.
