Duplication method for a clone remote control operating in radio frequency and capable to remotely control an electrical device by the pressure of at least one control key or button; said clone remote control comprising at least one memory, a transceiver and a microprocessor capable of executing a program for implementing the following steps: - enabling the clone remote control to a duplication phase by pressing said control key and simultaneously pressing a programming key for a predetermined number of times; - releasing the said keys (10, 11); - approaching the emitting ends of an original remote control to be duplicated and the clone remote control in the duplication phase; - pressing for a predetermined period of time a key of the original remote control, allowing said microprocessor to receive via the transceiver the working frequency and the code transmitted from the original remote control by means of a recognition and/or emulation procedure of the transmitted code; - pressing for a predetermined period of time a key of the clone remote control to assign to it the same function of said key of the original remote control; - storing in said memory said working frequency, the recognized code and the assigned key; - starting an automatic storing procedure that provides for the transmission of predetermined sequences of recognized or emulated codes toward the electrical device to be controlled, characterized by said storing procedure automatically forcing the storing of the recognized or emulated code on a receiver of the electrical device to be controlled by generating alternating old and new codes being transmitted towards the electrical device to be controlled in a predetermined storing sequence; and - repeating said storing procedure for a plurality of storing sequences being stored in said memory of said clone remote control until said clone remote control is recognized by said electrical device to be controlled. - enabling the clone remote control to a duplication phase by pressing said control key and simultaneously pressing a programming key for a predetermined number of times; - releasing the said keys (10, 11); - approaching the emitting ends of an original remote control to be duplicated and the clone remote control in the duplication phase; - pressing for a predetermined period of time a key of the original remote control, allowing said microprocessor to receive via the transceiver the working frequency and the code transmitted from the original remote control by means of a recognition and/or emulation procedure of the transmitted code; - pressing for a predetermined period of time a key of the clone remote control to assign to it the same function of said key of the original remote control; - storing in said memory said working frequency, the recognized code and the assigned key; - starting an automatic storing procedure that provides for the transmission of predetermined sequences of recognized or emulated codes toward the electrical device to be controlled, characterized by said storing procedure automatically forcing the storing of the recognized or emulated code on a receiver of the electrical device to be controlled by generating alternating old and new codes being transmitted towards the electrical device to be controlled in a predetermined storing sequence; and - repeating said storing procedure for a plurality of storing sequences being stored in said memory of said clone remote control until said clone remote control is recognized by said electrical device to be controlled.
