Key Blank



A key blank (sometimes spelled keyblank) is a key that has not been cut to a specific bitting. The blank has a specific cross-sectional profile to match the keyway in a corresponding lock cylinder. Key blanks can be stamped with a manufacturer name, end-user logo or with a phrase, the most commonly seen being 'Do not duplicate'. Blanks are typically stocked by locksmiths for duplicating keys. The profile of the key bow, or the large, flat end, often references an individual manufacturer.

Despite common belief, keys stamped with "Do not duplicate" or "It is unlawful to duplicate this key" are, with few exceptions, perfectly legal to duplicate. Some key blank manufacturers, such as Best Access Systems, strictly restrict the sale of their own blanks. However, while the company may not sell them directly, a consumer has every right to obtain blanks from a third-party manufacturer. Some blanks are made only in small volumes and are not widely available, but are not legally restricted. It is legal to fabricate such a blank on a CNC milling machine.
Keyblanks pre-stamped with powerless demands. These keys are not encumbered by patent and anyone is free to make them.ALOA, an internationally recognized association for locksmiths, also considers such stamps an empty threat.[1]Federal law regulates the duplication/fabrication of keys for use with locks owned by the US Postal Service and the United States Department of Defense.
