The present invention relates to a button-type car ignition system. The present invention includes: a housing the upper and lower portions of which are open; an upper plate coupled with an upper end of the housing; a moving button disposed inside the housing; a cover coupled with the lower portion of the housing; a printed circuit board disposed inside the housing; a key pad pressurized by the moving button; a light guide member that guides light generated by the light-emitting diode to the moving button; and an antenna coil that transmits and receives a wireless signal to and from an ignition key. According to the present invention, no additional components are required to install the antenna coil, and thus the number of components can be reduced, the number of assembly steps is reduced, and productivity is improved.
