A lockable utility box lid includes at least one aperture therethrough for receiving a fastener. The locking mechanism preferably includes a utility box engagement member coupled to the underside of the utility box lid. The locking mechanism is movable between a locked and unlocked position. A fastener extends through the opening in the utility box lid and engages the locking mechanism. Rotating the fastener in a first direction causes the locking mechanism to assume a first, locked position. Rotating the fastener in a second direction causes the locking mechanism to assume a second, unlocked position. In the locked position the utility box engagement member is engaged with an interior surface of the utility box lid.

1. A lockable utility box lid comprising: a utility box lid having an upper surface and a lower surface, a longitudinal axis extending from a first edge to an opposing second edge thereof, and at least one aperture therethrough for receiving a fastener;a locking mechanism comprising a utility box engagement member coupled to an underside of the utility box lid, the locking mechanism movable between a first position and a second position; anda fastener extending through the opening of the utility box lid and engaging the locking mechanism,wherein rotation of the fastener in a first direction causes the locking mechanism to undergo movement along the longitudinal axis of the lid and assume a first position wherein the utility box engagement member is engaged with an interior surface of the utility box,wherein rotation of the fastener in a second direction causes the locking mechanism to undergo movement along the longitudinal axis of the lid and assume a second position wherein the utility box engagement member is disengaged from the interior surface of the utility box,and further wherein said fastener does not extend above the upper surface of the lid when the locking mechanism is in the locked position or when the locking mechanism is in the unlocked position. 2. The lockable utility box lid of claim 1, wherein the utility box engagement member is a clamp. 3. The lockable utility box lid of claim 1, wherein the fastener is a security fastener. 4. The lockable utility box lid of claim 3, wherein the security fastener comprises a head sized and shaped in a non-standard manner to mate with a tool having a complementary size and shape. 5. A lockable utility box lid comprising: at least one utility box lid having at least one aperture defined therein;at least one clamping mechanism coupled to underside of the lid, the at least one clamping mechanism comprising: a bolt comprising a threaded first end and an opposing second end, the second end having an integral bolt head further including a cavity;a lock plate;a plurality of side plates coupled at right angles to said lock plate wherein said side plates are further coupled at right angles to the underside of the lid, whereby said lock plate is coupled to said side plates at a spaced location so as to allow a predetermined space between the opposing surfaces of said lock plate and said utility box lid;a back plate including a first bolt aperture pivotably coupled to said plurality of side plates;a pivot arm including a second bolt aperture pivotably coupled to said lock plate;a threaded plate having a threaded aperture pivotably coupled to said pivot arm; andmeans for urging said pivot arm of said clamping mechanism in an upwardly outward direction whereby said pivot arm is caused to forcefully engage one or more inward facing vertical, horizontal or angled interior walls said utility box enclosure. 6. The lockable utility box lid of claim 5, wherein said bolt is sequentially inserted through the first bolt aperture of the back plate, the second bolt aperture of the pivot arm and rotatably inserted into the threaded aperture of the threaded plate. 7. A lockable utility box lid comprising: a utility box lid comprising an upper surface and a lower surface and a longitudinal axis extending from a first edge to an opposing second edge thereof;at least one clamping mechanism attached to the lower surface of the utility box lid, the clamping mechanism selectively adjustable between a first locked position and a second unlocked position; andan actuator engaging said at least one clamping mechanism for selectively adjusting the clamping mechanism between the first locked position and the second unlocked position,wherein when moving from an unlocked position to a locked position the clamping mechanism moves outwardly with respect to a center of the utility box lid, and along the longitudinal axis thereof, to engage one or more interior walls of a utility box enclosureand further wherein said actuator does not extend above the upper surface of the lid when the clamping mechanism is in the locked position or when the clamping mechanism is in the unlocked position. 8. The lockable utility box lid according to claim 7, wherein the utility box lid defines an upper aperture having a first larger end and a second smaller end, further comprising: a lock plate fixedly attached to the lower surface of the utility box lid, the lock plate defining a lower aperture having a first larger end and a second smaller end,wherein the lock plate is oriented such that the first larger end of the upper aperture is aligned with the second smaller end of the lower aperture,and further wherein said clamping mechanism is selectively adjustable between said locked and unlocked positions by use of a tool extending through the upper aperture and the lower aperture. 9. A method of locking a utility box lid, the method comprising the steps of: providing a utility box lid having an upper surface, a lower surface, and a longitudinal axis extending from a first edge to an opposing second edge thereof, and having a security fastener and a locking mechanism associated therewith, the security fastener comprising a head sized and shaped in a non-standard manner; andproviding a tool for manipulating the security fastener, the tool having a size and shape complementary to the security fastener,wherein rotating the security fastener in a first direction causes the locking mechanism to undergo movement along the longitudinal axis of the lid and assume a first, locked position, and further wherein rotating the security fastener in a second direction causes the locking mechanism to undergo movement along the longitudinal axis of the lid and assume a second, unlocked position, and further wherein said security fastener does not extend above the upper surface of the lid when the locking mechanism is in the locked position or when the locking mechanism is in the unlocked position. 10. The method according to claim 9 wherein the locking mechanism comprises a clamp that engages an interior surface of a utility box when the locking mechanism is in the first, locked position.
