Trivia

 * In, the Wax Key perk will automatically give the Dragonborn a copy of a picked lock's key if it exists. This lets them open the lock later on if it resets.
 * The Irkngthand Consortium Key has no purpose within the game as there is no such location called Irkngthand Consortium and is only found on a random bodyguard belonging to Alain Dufont. The key should be ignored and not picked up.
