Fallout: New Vegas keys

General information
Keys in Fallout: New Vegas open specific doors or containers, some of which are inaccessible otherwise. Most keys can be found in the possession of non-player characters and can be pickpocketed while a few can only be retrieved if their owner has been killed. They appear in the Pip-Boy inventory in the keyring under the "Misc" heading. {{Legend}}
