A remote controllable laundry processing device includes: a cabinet main body including a door, a sensor unit configured to sense a locked state of the door, a manipulation unit provided for user input, a remote control setting unit configured to control the laundry processing device based on an external terminal, a controller configured to control an operation of the laundry processing device, and a communication unit configured to send the controller an input signal from the external terminal. The controller is configured, based on the door being in the locked state and regardless of whether a remote control has been set by the remote control setting unit, to control the laundry processing device in response to a first input signal from the manipulation unit and a second input signal from the external terminal and each of the first input signal and the second input signal is a pause signal.
