PURPOSE: A providing system of a vehicle location information and a method are provided to recognize the current location of a driver by indicating the difference in brightness of an LED(Light Emitting Diode) mounted on a smart key according to the size of a signal receiving and transmitting between the smart key and the vehicle. CONSTITUTION: A providing system of a vehicle location information comprises a vehicle and a smart key. The smart key comprises a plurality of buttons in order to remote control the partial function of the vehicle. The smart key comprises a first light emitting diode and a second light emitting diode. The closer the vehicle approaches, the brighter the first light emitting diode lights up when the user presses the prescribed button. The second light emitting diode has a light emitting color different from the first light emitting diode. [Reference numerals] (310) Button applied?; (320) Generating and transmitting a low-frequency signal; (330) Receiving a response signal within a reference time?; (340) Measuring the intensity of the response signal; (350) Calculating a voltage corresponding to the measured signal intensity; (360) Calculated voltage < Reference voltage ?; (370) Applying the calculated voltage to a first light emitting diode; (380) Transmitting an execution command for a function corresponding to the applied button; (390) Applying a voltage to a second light emitting diode; (AA) Start; (BB,DD,GG) No; (CC,EE,FF) Yes; (HH) End;
