Key Code
A key code is a series of alphanumeric characters used by locksmiths to create a key. There are two kinds of key codes: blind codes and bitting codes.2A8G Blind codes These are codes that require a chart or computer program to translate the blind code to a bitting code, which is used to create the actual key. Most key codes are blind codes, and publication of code books or software is restricted to licensed locksmiths in most jurisdictions for security reasons. Some locksmiths also create their own blind coding systems for identifying key systems they installed, or for customer identification and authorization in high security systems. Example: 23N7 (General Motors) or X2100 (Nissan) are examples of blind codes used for automotive ignition keys.

Bitting (key)
Bitting is the depth of key cuts on a cylinder key for a pin tumbler lock, often expressed as a number. Bitting also refers to the combination of key cuts on a bit key for a warded lock or lever tumbler lock. The exact geometry of modern keys is usually described by a code system. The bitting instructs a locksmith how to cut a certain key, to replace a lost key or make an additional copy. The bitting is usually a series of integers (e.g. 372164) that is usually translated from a key code chart or from a bitting code list to settings on specially designed key machines. In many code systems each digit in the bitting corresponds to a certain location on the key blank where a cut or notch is to be made and also indicates the necessary depth of the cut. Many lock companies use their own proprietary code system. Depending on the maker, the bitting sequence can be from bow-to-tip (the bow being the larger, handle portion of the key), or can be from tip-to-bow. A smaller number is typi ...

Master Keying
A master key operates a set of several locks. Usually, there is nothing special about the key itself, but rather the locks into which it will fit. These master-keyed locks are configured to operate with two, or more, different keys: one specific to each lock (the change key), which cannot operate any of the others in the set, and the master key, which operates all the locks in the set. Locks that have master keys have a second set of the mechanism used to operate them that is identical to all of the others in the set of locks. For example, master keyed pin tumbler locks often have two shear points at each pin position, one for the change key and one for the master key. A far more secure (and more expensive) system has two cylinders in each lock, one for the change key and one for the master key. Master keyed lock systems generally reduce overall security. The fact that some pin chambers have two shear points allows for more options when picking and it also allows for more keys t ...

Premier Election Solutions
Premier Election Solutions, formerly Diebold Election Systems, Inc. (DESI), was a subsidiary of Diebold that made and sold voting machines. In 2009, it was sold to competitor ES&S.
