Abstract
Disclosed is a method of locking the functions of a mobile telephone system. At least two lock codes are stored in a memory together with the functions to be kept locked or actuated when the locked state of the mobile system is released. The locked state of the automobile is not released unless a registered lock code is input. When the locked state is released by inputting one of the registered lock codes, some functions remain in the locked state in accordance with the input lock code, while other functions are actuated. Thus it is possible to limit the use of the mobile telephone system depending upon who drives the car.
