	~~'''Key control''' is the ability to control the distribution, duplication, and privilege level of~~ [[key]]s in a given keying system. The main focus of key control is protecting the bitting information of keys, limiting the availability of key blanks, and restricting methods of key duplication, even by legitimate users of the keying system.

	~~== Key duplication ==~~

	~~The ability to duplicate a key for a given system hinders the ability of the keying system to account for working keys and is a major problem for key~~ control. High security locks will provide keys that are mechanically difficult to duplicate without the assistance of special key cutting equipment. Modern key cutting equipment for high security locks will also have secondary measures to prevent arbitrary key bittings from being cut, usually through the use of [[security card]]s or an electronic database of customers and their keys.

	~~=== Do Not Duplicate ===~~
	Many keys are stamped with "Do Not Copy" (DNC) or "Do Not Duplicate" (DND) to prevent locksmiths from duplicating the key. This warning is rarely backed with legal ramifications and many locksmiths and key duplication centers will duplicate these keys provided they have the proper key blanks.

	~~=== Restricted Key Profiles ===~~
	Using a non-standard or custom key profile (the pattern of warding) can provide some measure of key control. Many key profiles are patent protected to prevent them from being manufactured by third parties, making obtaining key blanks more difficult. Many [[locksmith]] associations provide members with access to restricted keyways, making key duplication without authorization difficult.

	This feature does not prevent a medium to high skill attacker from machining their own key blanks or simulated keys. Several professional machines exist to create key blanks of arbitrary keys either using a working key or a photograph of the key profile. The most notable of these machines is the [[Easy Entrie]].

	Many keys are stamped with "DNC" to deter duplication of the key, however many hardware stores, shops that provide a key cutting service and even some locksmiths will copy the keys, as there are no laws in place to prevent duplication. Do Not Copy keys are seen as more of a deterrent to stop people from getting the keys copied, but more recently it's become apparent that most places that provide key duplication will duplicate DNC stamped keys without having the customer on file as owning the lock.
