A keychain (also key fob or keyring) is a small ring or chain of metal to which several keys can be attached. The length of a keychain allows an item to be used more easily than if connected directly to a keyring. Not only will a keychain allow you to keep track of where your keys are, but it will also keep your EDC secure and far away from pickpockets. There’s really no reason not to own a keychain If something or someone is kept under lock and key, they are in a container or room which has been securely locked. The books were normally kept under lock and key in the library vault. He is currently under lock and key at Eastmoor secure unit in Leeds. See full dictionary entry for lock.

A key tag is simply a way to display a barcode which, after all, is just a number. The number references a record in database that contains all the relevant check-in, loyalty and tracking information. The record may even contain a picture of the member. A lock is a mechanical device for securing a door, chest, or other receptacle so that it can only be opened by an authorized person. Most locks are opened by a key which is placed in the lock and turned. Combination locks do not use a key but rather have a cylinder that is turned to certain stops. While there is no professional consensus on how many keys are too many, most experts agree that five or six keys should really be the max amount. An even better option is to have your ignition key on its own keyring to completely reduce the weight pressing down on the ignition.
