In Small Harbor, there is a helicopter landing area instead of a large building with the Recycle Machine in front of it. Just opposite this area, you can see a two-story container with D11 written on it.

Enter this container marked D11, and put the Electric Fuse in the fuse box. Then turn the switch next to it to the green position. When you do this, electricity will go to the green door on the top floor of the container. You can then unlock the door with your Green Keycard.

In the big red warehouse by the sea, close to the train tracks, you will find a small container labeled D2.
If you are the first player to visit here, you can see that the door is boarded up. If this is the case, you can easily break this wooden barrier with Rock, which has 50 health.
Once inside, put your Electric Fuse in the box, and then immediately turn the outside switch located just behind the Fuse Box to the green position.
Then follow the cable from this switch, which will lead you directly to another container under the red hangar with the word H2 on it.
After that use your Green Keycard to open the door, and take the Blue Keycard along with the Crates inside.
