Abstract

PURPOSE: To prevent a key transmitter from being left in a case by a method wherein this system is formed that when a request transmitting means to transmit a request signal through control of a transmission control means, a lighted-on indicator is lighted off. CONSTITUTION: A request signal is transmitted to a key transmitter C from a request signal transmitting means B according to operation of a locking unlocking operation means A. A key code signal returned from a key transmitter receiver C is then received by a key code receiving means D, the code of a key code signal is compared with a preset code by a comparing means E. According to detection of coincidence by the comparing means E, the locking and unlocking state of a lock device F is indicated by lighting an indicator G. Simultaneously, through coincidence detection, a timer means H is clocked during a specified time and after a lapse of a specified time, a request signal is transmitted from a request signal transmitting means B by a transmission control means I. Further, the indicator G is lighted off by an indicator control means J.
