PURPOSE: A method and apparatus for processing multiple key input in a mobile terminal is provided to achieve the multiple key input of a mobile terminal by adding a key scan buffer to store a return line input value for each scan line and a key input buffer to execute processing for a key-pushed state and a key-pushed release. CONSTITUTION: A control part drives all scan lines so that a key-pushed state for a return line can be detected(601). The control part checks whether a return line input value is null(602). In case that a return line input value exists, the control part stores the value corresponding to the first scan line(603). Then the control part drives the first scan line(604) and checks whether a return line input value is null(605). If a return line input value exists, the control part stores it in a place corresponding to the present scan line of a key scan buffer(606). Then the control part checks whether the present scan is the last scan line(607).
