A door actuating system including a keypad type remote transmitter having a keypad for transmitting door open request signals generated by pressing the keys of the keypad and a stored code type remote transmitter, including a code stored in long-term storage for transmitting door open requests including the stored code. A receiver selectively opens the door responsive to the door open requests from both types of remote transmitters. The receiver includes a user settable security switch which inhibits selective door actuation responsive to door open request signals from the stored code type transmitter while permitting selective door actuation responsive to door open request signals from keypad type transmitters.
