Abstract
A system for remotely controlling the doors of an automotive vehicle with a reduced number of transmitters to be held and a reduced number of buttons of the transmitters is disclosed. The transmitter has a lock button and an unlock button. Upon depression of the lock button or the unlock button, a corresponding demand signal is transmitted repeatedly. The demand signal includes an ID code, a button code and a time code. The button code indicates the identification of the lock button or the unlock button. The time code indicates whether a button has been kept depressed for at least a predetermined length of time or the number of times the button is depressed. The receiver controls the door lock/unlock operation and the door open/close operation based on the button code and the time code. The time code can be replaced with a number-of-times code indicating the number of times a button is depressed.
