Acquiring the Key Mold

You will have to find out how to acquire Heisenberg's Key once you begin exploring the Heisenberg's Factory, a location visited in the final stage of the campaign.

Ethan must go through a very large part of the factory and ultimately reach the level B1 room pictured in the images above. You will find the Key Mold within.

Creating Heisenberg's Key

Bring the mold you just found to the Casting Machine located in the Foundry room on level MB4. Ethan visited this place earlier in the game, but he didn't have the necessary quest item with him back then.

Use the Key Mold and wait a while for Heisenberg's Key to be created .

Purpose of Heisenberg's Key

The key has two main uses. You can use it to unlock the optional Heisenberg's Quarters room on level MB4. There are some regular monsters inside and once you dispose of them, you will find lots of small loot and a Mechanical Part (Shaft) treasure that can be combined with the Mechanical Part (Cylinder) treasure that can be found in a different part of the factory.

The most important use of Heisenberg's Key is to open the door on level B1, near the elevator. This will allow you to continue the game and reach the Prototype Sturm boss fight.
