1. A slim smart card key for a vehicle, comprising:

  • 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,wherein the spare key settling part vertically protrudes by a predetermined length from the spare key receiving part on the PCB,wherein the spare key settling part comprises;

    an upper plate in which an upper portion settling part is formed, wherein the upper portion settling part protrudes upwardly toward a top of the spare key receiving part, is bent downwardly toward one side among directions orthogonal to a longitudinal direction of the spare key receiving part, and is extended in parallel;

    a lower plate in which a lower portion settling part is formed, wherein the lower portion protrudes downwardly toward a bottom of the spare key receiving part and is bent upwardly in one side among directions orthogonal to the longitudinal direction of the spare key receiving part; and

    a connecting plate which connects the upper plate, which corresponds to the other side among directions orthogonal to the longitudinal direction of the spare key receiving part, and an end of the lower plate,wherein a side portion settling part for holding the spare key settling part is formed in the connecting plate, andwherein the upper portion settling part, the lower portion settling part, and the side portion settling part sit on a top surface of the circumference of the spare key receiving part of the PCB.
