How to get the Airlock Key and Solve the Keypad Puzzle Upper Deck – SIGNALIS
What is an Airlock Key?
An airlock key is a magnetic keycard that allows access to Penrose’s airlock control. It is obtained in the PENROSE-512 mission.

Follow these steps to solve the keypad puzzle in the upper deck to obtain the Airlock key:
- Pick up the photograph on the Flight Deck and inspect it to find a combination. Remember the combination as you will be using it for later.

- In the mess hall, pick up the adhesive tape as you will be needing it for later.

- Enter the combination that was on the picture on the keypad to open the Cryogenics pod. Once opened, you will find a broken Airlock key.

- Use the adhesive tape to piece together the broken Airlock Key. To do this, combine the adhesive tape and the broken airlock key.
That’s it, we hope that this guide has helped you solve the Keypad Puzzle to obtain the airlock key.
