ABSTRACT:
A lock guard system for efficiently securing a dead bolt lock mechanism from outside access. The lock guard system includes a stop member comprised of a base including an upper slot and a plate that includes a lower slot for receiving a sleeve and fastener. The stop member connects to an existing dead bolt mechanism by extending the fastener and sleeve through the lower slot into an existing aperture in a covering plate. The stop member is able to adjust about the sleeve and lower slot to allow the dead bolt mechanism to operate both normally or to prevent the knob that controls the dead bolt from rotating.
