An overhead door lock comprising:

• a) a mounting plate mounted on an overhead door header inside of a garage, said mounting plate having a locking aperture therein;
• b) a barricade having an L-shaped bracket with one leg fastened to a top surface of an upper edge of an overhead sliding garage door and a faceplate affixed to an upwardly extending second leg of said bracket, said faceplate having an aperture therethrough and a flange mounted thereon extending generally perpendicularly to said faceplate, said flange having an aperture therethrough, said faceplate comprising a pair of legs joined at one end where said faceplate aperture is located, opposite ends of said legs being attached to said upwardly extending second leg of said bracket, said garage door being mounted so that when said garage door is in a closed position said faceplate is flush against said mounting plate with said aperture in said faceplate aligned with said locking aperture of said mounting plate, and when said garage door is opened said faceplate moves away from said mounting plate in a direction perpendicular to said faceplate;
• c) a coupling passing through said faceplate aperture and having a first end affixed into said mounting plate locking aperture when said garage door is closed and a second end having an aperture positioned such that when said first end of said coupling is inserted through said faceplate aperture and affixed into said mounting plate locking aperture, said coupling aperture and said faceplate flange aperture are generally coaligned;
• and
• d) a secure locking device extending through said coaligned coupling and faceplate flange apertures to prevent said door from being opened, said secure locking device being inside said garage when deployed on said flange and coupling so there is no access to said secure locking device from outside of said garage.
