A locking device for vehicles includes a card including a microprocessor and a transmitter for generating and transmitting commands for locking and unlocking the doors of a motor vehicle. A lock control device includes a microprocessor and a receiver for receiving the commands transmitted by the lock command device. The lock control device will only carry out a receive command if the command is applied to a specific motor vehicle and the motor vehicle is in the proper state to implement the command. Change data is generated by the lock control device and transmitted to the lock command device to change the value of the next subsequent lock command so that the lock command can be uniquely identified with the motor vehicle.

Locking device for vehicles

The present invention relates to a start controller for an engine of a vehicle comprising fuel supply means for supplying fuel to the engine at current flowing time, an electric driver for flowing a current to the fuel supply means, control means for holding a specific code, comparing an input code with the specific code to judge the coincidence and instructing to flow a current to the driver when both coincide; and means for inputting the code to the control means. Thus, the start controller can prevent the vehicle from being stolen.

Start controller for engine

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.
