Signalis Blank Keycard Puzzle Solution Guide

Very early in the Signalis medical department, you will come across a save point in the reception area near the elevator lobby and the east hallway. Just north of this room is the office, where you’ll find a contraption that requires a blank key. You won’t be able to solve this puzzle immediately, but it’s needed for the 5-lock door found later in the waiting room area.

This Signalis guide will walk you through how to get the blank key and solve the puzzle in the office so you can eventually open the 5-lock door and move deeper into the facility.

How to get the blank key

 

Before you even think about getting the blank key, you’ll need to solve the pump room puzzle to drain the water from the Protektor bathroom in the west hallway, the same place where you get the pump room key in the first place.

Once you solve the pump room puzzle, the water in the Protektor bathroom will drain, allowing you to jump to the lower floor. Do this and head for the door at the bottom right as you enter the flooded hallway. It’s the flooded storage room. The blank key is on a stack of boxes on the far right of the room.

How to solve the blank key puzzle

With the blank key in hand, return to reception, but do not go inside. Instead, enter the northern hallway. Go into Imaging and interact with the x-ray machine in the back. Select item “D”, which should be a keycard in some type of hardened plaster substance.

Activate X-ray and turn the item so that the black corner (not the black edge) of the keycard is facing down to “Toggle Image Mode”. You will notice that there are dots on the map itself and some of them are connected by a line. Snap a picture of the card or write down the design: you’ll need it shortly, and there’s no reason to memorize it and go back if you forget.

Return to the desk above reception and interact with the computer in the back. Insert the blank key. A key card image with the same dots as the x-ray card will appear on the computer screen, except they will not be connected by a line. You will also notice that the black part of the card is in the lower right corner.

The goal here is to trace the drawing from the x-ray map to the blank map in the computer. You have 8 moves. Here’s how to use them:

  • Start at the top left. Click on this node, then move:
    • Right.
    • Down.
    • Right.
    • At the top.
    • Down.
    • Down.
    • Right.
    • At the top.

Once you have traced the drawing, print the key and remove it. It will still be called the blank key, but don’t worry about that. Now take it with the Fire, Air, Water and Gold keys from the 5-lock door; insert it into the “E” slot (it’s a replacement for the Earth key, which doesn’t exist).

Once you have solved the blank key puzzle, you are one-fifth of the way to opening the 5-lock door in the waiting room and moving on to some of the more difficult areas of Signalis. For more guides, including how to solve the incinerator puzzle, click the link or head here to our guides hub for the Survival Horror Gem.
