Types of Keys

A key is a small piece of metal that is used to operate a lock ( to lock or unlock it). After all, keys are devices that are always with you.  You bring them in your pocket, on a chain, decorate a bunch of keys with charms, lose or give them to other people. So, which key to choose? Locks and keys were invented a very long time ago. The first keys, which historians are aware of made of wood, and later with the development of blacksmithing, they began to be made of metal.

Simple Modern Keys

Since then, the development of technology has moved far ahead and the keys, like locks, today are high-tech devices, with electronics, sophisticated laser cutting. Often they are paired with the appropriate cylinder that can serve as a reliable protection for your doors.

The simplest of the modern keys is “Pinocchio”. This is an ordinary key, without special secrecy, the essence of which is to reduce the mechanism to a flat tongue. In this key only the size of this tongue varies and the reciprocal mechanism inside too.

A key (door-lock) is an integral part of the every home. It is an item that contains the code of the mechanism of the locking device. In this article we will look at some types of keys and learn a little about the origin of their names.

Socket Wrench

The code elements of the lock with such a key are the plates, the name of which is the socket. Indeed, on safes you can find such locks, but they are specific and cannot be used on the doors in apartments. Therefore, the key and the lock are forked, but not safe.

English Key (Door Lock):

Its name speaks for itself because the first locks with a similar type of mechanism were developed in England. Some mistakenly call locks with such keys – English. This is not true, because manufacturers of locks with such mechanisms – are in mass all over the world. But the very type of the key has remained – English.

Perforated Key

The mechanisms with a similar key are produced in China and in Asia. The most correct names are “a key with a vertical cutting” or “a key with perforations”.

Finnish Key (Abloy):

This is a key of the lock with a disk type mechanism. It was first developed in Finland by ABLOY Corporation.

Pump Key/ Pump-Type Wrench

In order to open the pump lock, the key must be pressed into the mechanism and only then rotated. Having overcome the force of the loaded pump mechanism with the key, you type its code.


Electronic Code Key

Such type of keys has become widespread in recent years related to the massive installation of electromagnetic locks on the entrances of houses. Yes, the lock is electromagnetic, but the key itself does not have any magnets. It contains the information coded in electronic form. Therefore, the key to this lock is electronic code.

Despite some advancement in key design since, the majority of locks nowadays are still variants of the designs created by Yale, Chubb and Bramah.
