Chapter One: reception and basement
In the reception hall, a staff note is torn in two. One half sits with the Allosaurus fossil and the other at the base of the Brontosaurus mount, and together they give 9216 for the employees-only keypad. Behind that door is the token that opens the way to the theater.
Later, the gift shop basement keypad takes 1903. Down there you place three fuses while the mascot hunts you. The Bronto chase that follows sends you into the caverns.

Chapter Two: tower, bunker, lift and dynamite
After powering both generators, climb to the Foreman Tower and enter 0451 on the office door. Inside, the red button opens the base gate and you pick up the camera. The Bronto escape comes straight after.
The bunker keypad near the first door is broken, so take parts from the working keypad by the gate, repair it and enter 0978. At the lift, Stella calls with 1677, which opens another way to the elevator shaft. Near the end, 0180 opens the safe house locker that holds the dynamite.

Chapter Three has no keypad code
The Allosaurus rail cavern is a power puzzle rather than a code lock. You need four green indicators on the central fuse panel before you can leave. The last fuse is in a locked shed, and the key for it hangs in a raised key cabinet.
If a guide promises a Chapter Three door code, treat it with caution. None of the walkthroughs we checked list one. The padlocked gate in Chapter Two is also opened with a key from a gondola, not a number.
If a code is rejected
At least one fan guide says some codes may change between playthroughs. Most walkthroughs list the numbers above as fixed, but the note in your own game is the final word. Read the note or listen to Stella before assuming the game is bugged.
Dead by Daylight reward codes are a different thing entirely. Those are cosmetic codes you claim from the in-game Rewards tab, not keypad numbers. The DBD rewards page explains when each one unlocks.
