A drunk driving preventing device using a remote controller key of a vehicle is composed of: a remote controller key set comprising an alcohol sensor module(25) measuring drinking of the user, a speech recognition module(31) recognizing the user's voice, a display module(29) informing the drinking measurement result, a control unit receiving signals of the alcohol sensor module and the speech recognition module and outputting a control signal, and a transmitter(27); a receiver installed in the vehicle to receive a signal output from the remote controller key set; an RKE(Remote Keyless Entry,42) locking or unlocking a door according to the signal of the receiver; and an ECU(Electronic Control Unit,44) starting the engine. The remote controller key set has an unlock switch for unlocking the door. The unlock switch is also used as a power switch for supplying power to operate the alcohol sensor module and the speech recognition module.
