A door lock and fingerprint recognition module comprises a first circuit board, a shell, a light guide element, a second circuit board, a fingerprint recognition chip and a light source. The first circuit board comprises a first surface and a second surface which are opposite to each other. The shell is arranged on the first face and comprises an annular shell side wall, and an accommodating cavity is defined by the shell side wall and the first face together. The light guide element is arranged on the first face and contained in the containing cavity, the light guide element comprises a lightguide side wall and a step formed by extending from the light guide side wall to the center of the light guide element, and the light guide element and the first face jointly define a containing space. The second circuit board comprises an installation part and a connection part which are connected, the installation part is arranged on the step and contained in the containing space, and the connection part is electrically connected with the first circuit board. The fingerprint recognition chip is arranged on one side, far away from the step, of the mounting part and is accommodated in the containingspace. The light source is arranged on the first face and contained in the containing space. Light emitted by the light source in the fingerprint recognition module can be uniformly guided outfrom the light guide element.
