Slim-type smart card key of vehicle and control method therefor

Abstract

The present disclosure relates to a slim smart card key for a vehicle and a control method thereof, and improves assembly convenience and product durability by including including the following: a Printed Circuit Board (PCB) to which a plurality of electronic components are soldered, which has a predetermined thickness, and in which a spare key receiving part and a battery receiving part are formed, wherein the spare key receiving part is formed by vertically cutting one side of the PCB and thus is vertically hollow, and the battery receiving part is formed by vertically cutting the other side of the PCB and thus is vertically hollow; a body part which has a spare key entrance hole for inserting a spare key through the spare key receiving part, and a battery entrance hole for inserting a battery through the battery receiving part, and which is injection molded to embrace the PCB while the PCB is inserted into a mold; a spare key settling part which is moved toward the spare key receiving part from above or below the PCB before the body part is injection molded, and then sits on and fixed onto a circumference of the spare key receiving part; and a terminal assembly which is moved in the same direction as that of the spare key settling part before the body part is injection molded, and then sits on and fixed onto a circumference of the battery receiving part.
