* The Internet Corporation for Assigned Names and Numbers (ICANN) which runs the DNS (Doman Name System) and infrastructure that the entire internet runs on does something similar, though they use ''seven'' keys - seven encyrypted password keys entrusted to seven different people, which periodically need to be verified with another seven people at a "Root Key Ceremony".

* The nuclear missile locks in ''Film/TheHuntForRedOctober'' apparently had one of these. Although we never see the locks themselves, we see Captain Ramius taking possession of both keys -- which, as the doctor points out, sort of defeats the point. The movie plays with the idea that Ramius has gone mad and intends to start WW3, but in the novel [[Literature/TheHuntForRedOctober the novel]] this idea is rejected as five officers are needed to carry out a launch. It also stated that in the event of the political officer's death, the captain was ''supposed'' to take charge of his key. There were probably other standing orders as to who inherits the other keys in the event of any of the other officers with launch keys dying on a voyage as well. A two key (two combination in the book) system was also used on a safe in the submarine that contained the mission orders and code books. Moreover, while the movie version plays up that Captain Ramius took both launch keys as if he could single-handedly activate the missiles, the locks are intentionally positioned far apart enough in the room that it is ''physically impossible'' for one man to turn both keys simultaneously.

* ''VideoGame/TheCave'' has several puzzles require characters to pull switches/stand on pressure pads to allow other characters to past. Also a literal three-keyed-lock is in the scientist level.

* ''VideoGame/TheCave'' has several puzzles require characters to pull switches/stand on pressure pads to allow other characters to past. Also a literal three-keyed-lock is in the scientist level. This is in fact a central theme of the plot: the parties exploring The Cave are complete strangers with nothing in common save that they all have goals they can't seem to achieve, and this place makes those goals achievable - but not without the assistance of said strangers. This trope is thus pervasively used (both out-of-game by the designers and in-game by The Cave itself) to turn WhatYouAreInTheDark into a ''group'' experience.
