Many luxury cars come with a valet key. It is a special key you give the parking attendant and unlike your
regular key, will only allow the car to be driven a short distance while blocking access to the trunk and the on-
board cell phone. Regardless of the restrictions the valet key imposes, the idea is very clever. You give
someone limited access to your car with a special key, while using another key to unlock everything else.
