A latch assembly with a keyed rose plate for quick and easy adjustment to doors of different thickness without the use of threaded components. The latch assembly includes a latch body with an outside end having at least two grooves. The grooves are preferably spaced longitudinally apart from one another by one-half (1/2) the difference in standard door thickness. An outside rose plate has an oblong central opening which allows it to fit eccentrically over the outside end of the latch body. Once aligned with one of the grooves, the outside rose plate may be moved laterally with respect to the latch body to engage in the groove with which it is so aligned. An inside rose plate fits over the inside end of the latch body so that the inside rose plate is free to move longitudinally along the inside end of the latch body. By engaging the outside rose plate in the appropriate groove for the door thickness and fixing the rose plates to one another and snug against the door, the latch body is maintained in the center of the door. The engagement of the outside rose plate in one of the grooves secures the rose plate axially and rotationally with respect to the latch body.
