<p>PURPOSE:To change password codes without using a dedicated switch by satisfy ing the operation condition of a switch means and storing transmitted codes as new password codes. CONSTITUTION:The switch means is provided with a lock/unlock detection switch 14, an ignition switch 12 and a door curtain switch 18. The switch 14 links with a door knob to detect whether a door is in a door lock state or an unlock state. On the other hand, when the switch 12 turns on, the power source is supplied and the switch 18 links with the opening/closing of the door to detect the opening/closing state of the door. Then, a microcomputer 16 detects the operating state of the switch to recognize that the result of the detection satisfies an operation condition showing that the operation is the prescribed operation of the switch means. Furthermore, when detecting the reception of transmitted codes, the codes are stored in EEPROM 19 as new password codes. Thus, the password codes can be written and changed without using the switch dedicated for writing.</p> |
