If a fob broadcasted the same signal each time it unlocked the door remotely or opened the trunk, this could permit thieves with a tech-savvy mindset to connect vehicles to hot wires and drive them away. Thankfully, this is not an issue because smart keys emit a different encrypted signal each when the door is opened or the trunk is opened remotely.
