An alignment tool for preparing through holes in a door to enable mounting a lock assembly includes a slidable bracket for securely positioning the tool in the mortise at the edge of the door. An angle element is connected to the bracket and to a support plate, which is perpendicularly disposed relative to the bracket. The support plate is formed with precisely positioned guide holes that indicates to the door installer exactly where the through holes are to be made.
