An elongated base block of hard metal material has a flat upper surface to act as an anvil for a key resting on such surface. A narrow key-clamping rail extends lengthwise of the anvil and thumbscrews at its opposite ends may be turned to clamp the key. A die for debossing indicia in the key can be positioned vertically by holding it against a vertical surface of the rail. Alternatively, a die can be positioned in an upright guide slot of a carriage or saddle movable along the rail and sized to closely receive the die. By maintaining the die with its length precisely perpendicular to the upper surface of the anvil and, consequently, the key, a uniform impression in the key is assured when the die is struck.
