In Horizon Forbidden West, you are going to encounter locked doors that require codes. You can usually find these codes by exploring the nearby area and solving a puzzle.

The Side Quests Door Codes

In Horizon Forbidden West, there are a whopping 28 side quests, and that does not include the errands. In these side quests, there is only one that has locked doors, where you need to enter their codes to unlock the doors.

Here are the door codes for this side quest and where to find and enter them:

Forbidden Legacy Code #1 (1-0-2-0-2-3):

  • You’ll need this passcode after the objective “Jump to the Tower.”
  • In the tower, there is a locked door where you need to enter the code.
  • Find the code by scanning the Datapoint in a small room to the left of the locked door.
  • The Datapoint mentions that the code is the date Atbay was founded, which Alva confirms as “October 2023,” giving you the code 10-2023.

Forbidden Legacy Code #2 (4-0-2-6-2-5):

  • After entering the room, you’ll receive the objective to “Unlock the Door.”
  • There will be four artifacts in the back of the room that you need to scan from left to right.
  • Alva will provide numbers for each artifact, and you’ll need to figure out the code based on her comments.
  • Here’s what she says for each artifact:
    • “40”
    • “The H2Flow.”
    • “The company’s 25th anniversary. Looks like it used to be on the last pedestal.”
    • “The Dragonfly 6.”
  • So, the code you get is 40-2-6-25, with the “25” being placed last as it used to be on the last pedestal.

The Relic Ruins Door Codes

The Relic Ruins consists of multiple puzzles that you need to solve to get the code for the door. There are 9 Relic Ruins in Horizon Forbidden West, and five of them have a code for the doors. By far, the Relic Ruins have the most difficult of puzzles to solve for you to get the code. That’s why I have a separate detailed guide on how to get all the Relic Ruins, including the door codes puzzles.

Rewards for Completing the Forbidden Legacy Quest

Complete the extensive Forbidden Legacy side quest in Horizon Forbidden West by following Alva to the research facility and then proceeding to the ruins to recover lost data. Travel to Atbay Headquarters to find an entrance, unlock the first door, ascend to the Ancestor’s office, and open the last locked door to finish the quest.

Rewards for completion include 2 Bronze Ingots, 1 Ancient Chime, 1 Ancient Necklace, 2 Ancient Sculptures, and an Ancient Black Bracelet. Earn the “Recovered Alva’s Data” trophy and progress toward the game’s Platinum trophy. Return to Legacy’s Landfall after finishing the quest to receive the Utaru Protector Outfit from Alva near a campfire.

With that now, you know all the codes for the doors in Horizon Forbidden West. This includes all the codes for story quests, side quests, and the Relic Ruins.
