A locking mechanism for securing a component card to a main board is provided and includes a base having a top portion with a beveled edge and a coupling portion engageable with the main board. The locking mechanism includes a sliding element slidably, coupled to the base, having an extended protrusion. The sliding element is slidable between a locked and an unlocked position, where the protrusion is displaced towards the base in the unlocked position. The locking mechanism includes a biasing element between the base and the sliding element within a protuberance opposite the protrusion. The biasing element urges the sliding element toward the locked position. The protuberance includes an aperture formed at an end opposite the protrusion and allows a portion of the biasing element to pass through. In the locked position, a bottom surface of the protrusion and a top surface of the base define a receiving space.
