A method and apparatus for assisting in the operation of a key in a lock. A leverage extender is provided having a base member comprising a pair of opposed ends secured to a pair of opposed sides and a pair of opposed tops secured respectively to the opposed ends and the opposed sides such that a longitudinal aperture is formed therebetween. A handle member is secured to one of the opposed sides, comprising an angular disposition relative to a plane of the base and having handle sides thereof parallel to the opposed sides. At least one set screw aperture is disposed in one of the opposed sides and is adapted to threadably receiving a set screw. A set screw member is threadably disposed in the set screw aperture. The apparatus is secured to flanges of a lock cylinder and a key is passed between the top members of the leverage extender and into the lock cylinder. Force is then applied to the handle member to operate the lock cylinder. Alternatively, a head of the key is secured to the leverage extender, and the key/leverage extender combination is disposed in the lock to subsequently turn the handle member of the leverage extender and operate the lock.
