Fallout: New Vegas keys

General information
Like Fallout 3, 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.
