The entire lock mechanism is enclosed in an iron box called palastro. This box is composed of a rectangular bottom on which raised edges or folds are applied, of which the three through which the latch does not pass are called the partition. Sometimes, instead of bending the iron to form the box, the edges are built separately, leaving projecting tails that rest on the pallet.

The latch of the lock is a type of bolt moved by a key. The latch head is the part that comes out of the lock. On one side, the latch has some protruding parts or barbs on which the key works, on the other there are notches on which the spring retainer falls, an essential part to retain the latch in its place and prevent it from running without the action of the key which, at the same time that it pushes the latch through one of the barbs, lifts the spring and removes the retainer from its place. The latch is simple or rake depending on whether it is made of a single piece or has several teeth. On the inside of the lock there are certain contoured pieces that fit into cutouts in the key called guards. These serve to oppose the movement of any key that does not have the provided notches. The key is made up of the ring in which the nano is applied, the trunk pierced with a button and the bit. The bit consists of the nose, the flat and curved part that touches the lock latch, and the body, which is the part between the nose and the trunk. The bit has different notches to make way for the lock guards which receive different names depending on their positions such as the screw, the horn, the accomplished cross, the Caravaca, the muleta, the staff, etc. The trunk does not always have a cylindrical hole, sometimes it is clover-shaped, spear-shaped, etc. All these holes correspond to the tang of the lock fixed solidly to the palastro.[1]​.

La cerrajería es un oficio tradicional, y en la mayoría de los países requiere la realización de un aprendizaje. El nivel de educación formal requerido varía de un país a otro, desde que no se requieren calificaciones en absoluto en el Reino Unido,[3]​ a un simple certificado de formación otorgado por un empleador, a un diploma completo de una ingeniería de universidad. Los cerrajeros pueden ser comerciales (trabajando en una tienda), móviles (trabajando en un vehículo), institucionales o de investigación (cerrajeros forenses). Pueden especializarse en un aspecto de la habilidad, como un especialista en cerraduras de automóviles, un especialista en sistemas de llaves maestras o un técnico de cajas fuertes. Muchos también actúan como consultores de seguridad, pero no todos los consultores de seguridad tienen las habilidades y el conocimiento de un cerrajero.

Históricamente, los cerrajeros construían o reparaban una cerradura completa, incluidas sus partes constituyentes. El auge de la producción en masa barata ha hecho que esto sea menos común; la gran mayoría de las cerraduras se reparan mediante reemplazos similares, siendo las cajas fuertes y cajas fuertes de alta seguridad la excepción más común. Muchos cerrajeros también trabajan en cualquier hardware de puerta existente, incluidos los cierrapuertas, las bisagras, las cerraduras eléctricas y las reparaciones de marcos, o dan servicio a cerraduras electrónicas") haciendo llaves para vehículos equipados con transpondedor e implementando sistemas de control de acceso.

Aunque la instalación y sustitución de llaves sigue siendo una parte importante de la cerrajería, los cerrajeros modernos se dedican principalmente a la instalación de juegos de cerraduras de alta calidad y al diseño, implementación y gestión de sistemas de llaves y control de llaves. Con frecuencia, se requiere que los cerrajeros determinen el nivel de riesgo para una persona o institución y luego recomienden e implementen combinaciones apropiadas de equipos y políticas para crear una "capa de seguridad" que exceda la ganancia razonable de un intruso.

Key duplication

Traditional "key cutting" is the primary method of key duplication. It is a subtractive process" named after the cutting metalworking process, where a flat key "blank" is ground to form the same shape as the "jig key (original). The process approximately follows these stages:.

Modern key cutting replaces the mechanical aspect of the key with a process in which the original key is electronically scanned, processed by software, stored, and then used to guide a cutting wheel when a key is produced. The ability to store electronic copies of the key shape allows key shapes to be stored for cutting by any party who has access to the key image.

Different key duplicating machines are more or less automated, use different milling or grinding equipment, and follow the design of turn-of-the-century key duplicators.

Key duplication is available at many hardware stores, retailers and as a specialist locksmith service, although the correct key blank may not be available. More recently, online services for key duplication have become available.

A keyhole is a hole or opening (as in a door or lock) to receive a key.[4] Lock keyway shapes vary greatly depending on the lock manufacturer, and many manufacturers have a number of unique profiles that require a key blank specifically milled to engage pin tumbler locks).

Heraldry

The keys appear in various symbols and coats of arms, the best known being that of the Holy See:[5]​ derived from the phrase in which Saint Peter, in the Catholic tradition the first pope, promises, the Keys of Heaven"). But this is by no means the only case. Many examples are given in Commons.

Work of art

Some works of art associate keys with the Greek goddess of witchcraft known as Hecate.[6]​.

Palestinian key

The Palestinian key is the collective Palestinian symbol of their lost homes in the Nakba, when three-quarters of the Palestinian Arab population of British Mandate Palestine were expelled or had to flee the push of Israeli troops in the Arab-Israeli war of 1948, and were subsequently denied the right to return.[7][8][9] Since 2016, a Palestinian restaurant in Doha, Qatar, has held the record. Guinness for the largest key in the world: 2.7 tons and 7.8 x 3 meters.[10]​[11]​.
