The 4-digit code in Q Lab is 4397 for the cabinet, and 1324 for the armory door. The cabinet code comes from the car’s license plate in the stress test room, while the armory code comes from the shooting range leaderboard.

Where to find it

  • Cabinet code: 4397. Look in the stress testing room and check the car’s plate for the number.
  • Armory code: 1324. Check the shooting range leaderboard; the top score is the code.

In-game tip

If you’re standing in Q Lab and only need the cabinet, use 4397. If you’re trying to open the locked armory door, use 1324.
