What is Skeleton key?
[[File:Skeletonkey.png|thumb|right|A padlock skeleton key that can open any lock with this keyhole (right), compared to a normal key that can open only the lock for which it was made (left)]] A '''skeleton key''' (also '''master key''' or '''pass key''') is a [[key]] that can open all of the [[lock]]s in a set. For example, in an [[office]] building, each [[employee]] would have a key that only opens his/her office, and the [[manager]] or owner would have a key that opens all of the offices in that building. More complicated setups are also possible. For example, if there are [[cleaner]]s in the office building, and each cleaner only cleans one floor, the cleaner for a each floor could have a ''sub-master'' key that opens only the offices on that floor, while each employee still has a key that opens only his/her office and the manager still has a key that opens all of the doors. The exterior doors might also be configured so that they can be opened by any employee key, cleaner key, or the manager's master key. The more complicated the setup, the more important it is to use locks that have a large number of key possibilities. [[Disc-detainer lock]]s are especially suitable for master keying due to their large number of key possibilities. {{stub}} [[Category:Locks]]
