Authorized Operation of Vehicles

A system for enabling a candidate driver to start a vehicle, comprising:

• a key fob comprising a plurality of signal generators each coupled to a common antenna and configured to generate an encrypted RF signal at a specific frequency, one of the encrypted signals being a signal recognizable by the vehicle's computer system as presence of the key fob, the generators, except the generator providing the signal recognizable by the vehicle's computer system as presence of the key fob, powered from a common battery through individual dedicated normally-open (NO) switches, a microprocessor executing first coded instructions from a data repository coupled to the microprocessor, wireless communication circuitry coupled to the microprocessor;
• and a (NO) remotely-operable switch positioned in the circuitry in a manner that prevents, when open, generation of the encrypted signal indicating presence of the key fob;
• and
• a smartphone executing a mobile application generating an interactive interface on a touchscreen display of the smartphone at least enabling a candidate driver to log in to the mobile application;
• wherein the candidate driver logs in to the mobile application, the mobile application determines if the candidate driver is authorized to start and operate the vehicle, and if so, transmits a signal to the microprocessor via the wireless communication circuitry, causing the microprocessor to close the NO remotely-operable switch positioned in a manner to prevent, when open, generation of the encrypted signal indicating presence of the key fob, closing the switch signaling the vehicle's computer system to enable the starter pushbutton such that the candidate driver may start the vehicle.
