Read the clue in your own game first. Reception and repair-gate reports differ. Values below are source-reported, not independently playtested.
Chapter 1 / LOCK 01Conflicting reports
Reception staff door
9216
3929
Find the clue Collect the torn paper from the Allosaurus skeleton’s hand and the piece at the Brontosaurus display base. Read the completed hint at your own keypad.
Into Indie Games reports 9216; 9Puz’s gameplay image shows 3929. Neither is presented here as a universal code.
Find the clue Repair the damaged panel with parts from the working keypad reached by the hanging-platform route. Inspect the nearby monitors and the current objective.
Into Indie Games labels a bunker gate 0978. 9Puz shows a worksite monitor reading 7652 during a repair-gate sequence. Their exact correspondence is unresolved; do not assume these are two distinct required locks.
Use your own in-game hint first. Public guides disagree about reception and a Chapter 2 repair gate. These cards preserve those differences instead of presenting an untested list of seven fixed passwords.
A code is rejected — what next?
Match the location, not just the chapter. Several keypads appear underground.
Finish the relevant paper, conversation or repair objective.
Read the objective, monitor or keypad hint again. Preserve initial zeroes.
If the panel is broken, a different number will not repair it. Get the replacement parts first.
The differences above do not, by themselves, prove that codes are randomized. These are door passwords, not downloadable rewards or Dead by Daylight redemption codes.
