Ornate Brass Keys are used for furniture and cabinets on drawers, doors, desks, boxes and chests. The excellent quality and vintage style make these solid brass keys great replacements. Key blank, also known as key-bit, has solid end. This end must be cut to fit lock and engage lock-mechanism. If key bit is not correctly notched it will not open and close lock. These keys are hollow, to slip onto lock pin. Lock pin must be slightly less than 1/8" for barrel to slip lock-pin.
