Abstract
A keyless ignition start system in which authentication of a coded key fob is carried out twice, first to activate the ignition switch to allow starting the engine and second at the time when the brake pedal is depressed to put the car in a drive gear. The two step authentication prevents driving off a car which has been started without having the key fob for security purposes and also to avoid inconvenient situations that can otherwise occur.
