Abstract
A keyless entry system for use with a key for operation within the key receptacle to start an engine. The key is arranged to transmit a first ID code specified therefor when the key is operated within the key receptacle to start the engine. The transmitted first ID code is compared with a second ID code registered in an antitheft control unit. The engine is permitted to start if the transmitted first ID code is identical with the registered second ID code. A mobile transmitter is used for transmitting a third ID code specified therefor along with a command for vehicle door lock/unlock remote control. The transmitted third ID code is compared with a fourth ID code registered in a keyless entry control unit. The remote control specified by the transmitted command is permitted if the transmitted third ID code is identical with the registered fourth ID code. The keyless entry control unit registers the fourth ID code therein based on the transmitted first ID code.
