In automatic door locking apparatus and method for an automotive vehicle for locking and unlocking vehicle doors, a first timer unit in a controller starts a counting operation of a first set time period responsive to an unlock signal generated by a comparator so arranged as to compare a signal received by a receiver of a keyless entry system from a transmitter carried by an authorized operator operated to transmit a coded unlock signal with a preset code stored in a memory so as to determine whether the received code matches the preset code and, upon a match, to generate the unlock signal. When the first set time period is passed with no door of the vehicle opened, the automatic door locking is carried out via a door lock actuator to lock the vehicle doors. However, in the automatic door locking apparatus and method, the first set time period is extended so as to extend the automatic door locking when an unlatched signal indicating that a trunk lid of the vehicle is unlatched during the counting of the first set time period is detected.
