keychain , or keyring , is a small chain, usually made of metal or plastic, that connects small items to keyring. The length of the key chain allows the items to be used easier than if connected directly to the keyring. Some keychains allow one or both to end the ability to rotate, keeping keychains not bent while items are in use.
Keychains can also be a link between keyring and individual belts. Usually employed by personnel whose job requires frequent use of keys, such as security guards, prison officers, janitors, or retail store managers. These chains are often drawn, and therefore may be nylon ropes, not actual metal chains. The chain ensures that the key remains attached to the individual using it, making accidental losses impossible, and saving usage and tearing on the user's pocket.

Use of keychains
Key Chain is one of the most common souvenir and advertising items. Keychains are usually used to promote business. Standard advertising keychains will carry business names and contact information and often are logos.
In the 1950s and 1960s, with the improvement of plastic manufacturing techniques, promotional items including keychains became unique. Businesses can place their names on a three-dimensional promotional keychain at a lower cost than standard metal keychains.
Keychains are small enough and cheap enough to be promotional items for larger national companies that might give them millions. For example, with the launch of a new movie or television show, the companies may partner with a food company to provide keychain characters in each cereal box.
The key chain that currently holds the key is the stuff that has never been long mistaken by the owner. People sometimes attach their keychains to a belt (or belt) to avoid losing or to allow quick access to it. Many keychains also offer the owner desired function easily as well. These include army knives, bottle openers, electronic organizers, scissors, address book, family photos, nail clippers, pill boxes and even pepper sprays. Modern cars often include keychains that serve as a remote to lock/unlock the car or even start the engine. The electronic key finder is also a useful item that is found on many keys that will sound when called to find fast when misplaced.

Keyring
A keyring or "split ring" is a ring that holds keys and other small items, which are sometimes connected to keychains. Other keyrings are made of leather, wood and rubber. Keyring was discovered in the 19th century by Alexander Parkes. The most common form of keyring is a single piece of metal in a 'double loop'. One end of the loop can be opened openly to allow the key to be inserted and glide along the spiral until fully bonded to the ring. New carabiners are also commonly used as key chains for easy access and exchange. Often keyring is decorated with key locks for self-identification.
Other ring forms may use a metal or plastic circle with a mechanism to open and close the circle safely.
Key fob
The key keys are generally decorative and sometimes useful items many people often carry with their keys, on rings or chains, to facilitate tactile identification, to give a better handle, or to make personal statements. The word fob may be associated with a low German dialect for the word Fuppe , which means "pocket", however, the origin of the word is actually uncertain. The Fob Pouch (meaning 'sneak evidence' of the German word Foppen) is a pocket meant to prevent thieves. A short "fob chain" is used to cling to items, such as pocket watches, placed in these pockets.
Fobs vary greatly in size, style and functionality. Most often they are simple discs of fine metal or plastic, usually with messages or symbols such as logos (as with conference paraphernalia) or important group affiliate marks. A phob may be symbolic or very aesthetic, but it can also be a small tool. Many fobs are small flashlights, compasses, calculators, folding knives, discount cards, bottle openers, security tokens, and USB flash drives. Because electronic technology continues to be smaller and cheaper, the key-fob miniature version of (previous) larger devices becomes common, such as digital photo frames, remote control units for garage door openers, barcode scanners and simple video games (eg Tamagotchi) or other gadgets like breathalyzer.
Some retail companies like petrol stations keep their bathrooms locked and customers have to ask for a key from the clerk. In such cases, keychains have a very large fob so it's hard for customers to come out with a key.
Fobs access control key
Key access control fobs are electronic key fobs used to control access to buildings or vehicles. They are used to enable things like remote keyless entry systems on motor vehicles. The initial electric lock fobs are operated using infrared and require a clear line of sight to work. These can be copied using a programmable remote control. The newer models use challenge response authentication over radio frequency, so this is more difficult to copy and does not need line-of-sight to operate. This remote programming sometimes requires automotive dealers to connect diagnostic tools, but many of them can be programmed themselves by following the sequence of steps in the vehicle and usually require at least one working key.
Key fobs are used in apartment buildings and condominium buildings to control access to public areas (eg, loby doors, storage areas, fitness room, swimming pool). It usually contains passive RFID tags. The fob operates in the same way as proximity cards to communicate (via the reader pad) with a central server for buildings, which can be programmed to allow access only to areas where tenants or owners are allowed to access, or only within a certain timeframe.
Telecomunication can also use a security token - an electronic device often referred to as fob - that provides one part of a three-way match to enter through an insecure network connection to a secure network. (The famous example is the RSA SecurID token.) This key fob type may have a keypad where the user must enter a PIN to retrieve the access code, or it can be a screen-only device.
RFID key phobs can be easily cloned with tools like Proxmark3, and there are several companies in America that offer this service.
Cost
The cost of a key ring varies greatly depending on their purpose. Keychain ads start only a few cents per piece up to a few dollars each. They are usually purchased in bulk often over 500 at a time.
Key chains are found in retail stores to represent things like television shows, movies, video games, nostalgia, hobbies, interests, and personalities. This key ring ranges from one dollar to ten dollars and more.
Electronic key chains include games and small organizers ranging from a few dollars and can be up to 50 US dollars. Other key chain electronics include cameras, digital photo frames, and USB drives costing 10 to 100 USD.
Souvenir key chains are one of the most popular keychains on sale. This is a keychain that represents a trip or location that a person visits. This usually costs 1 to 10 USD.
As collectibles
The most popular collection of keychains focused on ads, souvenirs, monuments, popular characters and nostalgia-related items.
Collectors display and store their keychains in several different ways. Some collections are small enough so that collectors can place all of their keychains on their standard keychains. Some larger collections can be stored and displayed on pens, cork boards, tool shelves, on large connecting chains, in display cases, hanging on the wall, displayed on a Christmas tree. Some of the collections are large enough so the whole room is dedicated to the collection of keychain.
According to Guinness World Records, Brent Dixon of Georgia, the United States currently holds the world record for the largest collection of key chains, at 41,418 which are not duplicated.
Keychains do not store their value as well as other collections. The standard key chains purchased for the new five dollars may be worth less than a dollar after being owned without regard to conditions.

Computer keychain
By the analogy of physical objects, the terms keychain and keyring are often used for software that holds cryptographic keys. The term key chain was first introduced in a series of IBM developerWorks articles. This term is used in the GNU Privacy Guard to store known keys on a keyring. Mac OS X uses a password storage system called Keychain. "Keyring" is also the name of a password manager application that works under the GNOME desktop manager (used for example in the Ubuntu operating system). In cryptography, keyring is the database of some keys or passwords. There is also a portable password management program, such as keepass and keepassx.
