A keychain or key chain is a small chain, usually made from metal or plastic, that connects a small item to a keyring. The length of a keychain allows an item to be used more easily than if connected directly to a keyring. Some keychains allow one or both ends the ability to rotate, keeping the keychain from becoming twisted, while the item is being used. A keychain can also be a connecting link between a keyring and the belt of an individual. It is usually employed by personnel whose job demands frequent use of keys, such as a security guard, prison officer, janitor, or retail store manager. The chain is often retractable, and therefore may be a nylon rope, instead of an actual metal chain. The chain ensures that the keys remain attached to the individual using them, makes accidental loss less likely, and saves on wear and tear on the pockets of the user.
A keychain can also be a short chain used to link together a number of keys or other items. Sometimes keychains are even hung on walls.
Items commonly attached via a keychain or keyring include:
Bottle openers
Compasses
Credit cards
Digital sound recorders
Electronic games
Flashlights
Keyrings
Lanyards
Laser pointers

Logos, slogans, or phrases
