PURPOSE: A wireless hands-free system having an RKE(Remote Keyless Entry) function is provided to integrate a hands-free function with the RKE function into one module, and to use the hands-free function in a car, then to use the RKE function out of the car, thereby improving speech quality without carrying a hands-free line. CONSTITUTION: A dongle RKE(20) is connected with an earphone terminal of a cellular phone(10), performs a wireless call function with a hands-free unit(30) installed in a car through Bluetooth communication, and wirelessly outputs a control signal by selecting a door control button. A door control module(40) controls lock/unlock and trunk open functions of a door by inputting a door control signal. The hands-free unit(30) is installed on a front side of the car, carries out a wireless call function with the dongle RKE(20) through Bluetooth communication, receives the door control signal from the dongle RKE(20), and outputs the received door control signal to the door control module(40).
