<p>A transmission code 15 consisting of a transmitter ID code 16 and a operation switch control code 17 is transmitted through actuation of operation switches A and B of a transmitter 1. In a program mode of a receiver 4, a function selection code corresponding to the thus-received transmitter ID code is entered by utilization of courtesy switches 26 and 27 mounted on doors, and the thus-entered function selection code is set in a first memory location 37 in a rewritable manner. In an operation mode of the receiver 4, when a match exists between the transmitter ID code transmitted from the transmitter 1 and the contents of the first memory location 37, a function selection code is read. Operation information corresponding to the control code is read from the second memory location 38, and the operations of the lock mechanisms 5, 6, and 7 are controlled on the basis of the operation information.</p> |
