Abstract
An ignition start system in which authentication of a key is carried out twice, first to activate the ignition switch to allow starting the engine and second at the time prior to moving the vehicle from a parked position. The two step authentication prevents driving off in a car that has been started without having the key for security purposes and also to avoid inconvenient situations that can otherwise occur.
