A key case comprises three parts, a center body, a first case piece, and a second case piece. The center body has a first cavity which side facing the first case piece is opened. The second case piece has four tabs extending toward the first case piece at positions substantially opposite to the peripheral surface of the first cavity. Each tab includes a claw on its distal end. The center body has apertures through which the corresponding tabs can pass therethrough. Following to each aperture, a groove and a shoulder are formed in the peripheral surface of the first cavity. A wireless module is contained in the first cavity while claws pass through the corresponding apertures to be engaged with the shoulders. The wireless module is sized to prevent the claws from disengaging from the shoulders.
