Abstract
An ignition system for vehicle includes switching means which is turned on in response to a given code input. The switching means may be connected in a supply line which provides a connection between a primary coil of an ignition circuit and a storage battery mounted on a vehicle, in a ground line which provides a connection between the primary coil and the electrical ground of a vehicle, or in an energization control line which provides a connection between the base of a switching transistor, acting to pass or interrupt the primary current flow, and its associated base driver, each line being disposed in an ignition circuit. The code may be entered through numerical keys, a combination of a key code emitter and a key code receiver, or a combination of a key card and a card reader. The ignition circuit is completed by allowing the switching means to be turned on only when a code entered matches a specific code which is previously stored.
