Duplication method for a remote control operating in radio frequency and remote control thus obtained

The present invention refers to a duplication method for a 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. The remote control comprises 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 control and programming keys; - approaching the emitting ends of an original remote 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 which assign 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 a control procedure that provides for the transmission of the recognized or emulated code toward the electrical device to be controlled; - confirming the storage of said recognized or emulated code also on the electrical device to be controlled, if the control procedure has succeeded.
