DOOM 3 locker codes: Mars City, Administration and Alpha Labs
Look up selected original-campaign lockers and read the PDA clues that identify them.
Edition covered
The original 2004 PC DOOM 3 campaign and its separate handheld flashlight. BFG Edition changes flashlight behavior and other details; Resurrection of Evil and The Lost Mission are separate campaigns. Images are original PC publisher screenshots.
Match number and location
Some numbers are reused later, so a locker number alone is not always enough. These selected early entries pair the number with a named campaign area.
| Locker | Area | Code |
|---|---|---|
| 001 | Mars City maintenance | 396 |
| 023 | Mars City Underground | 531 |
| 017 | Mars City infirmary on return | 347 |
| 013 | Administration | 586 |
| 009 | Alpha Labs Sector 1 | 752 |
| 038 | Alpha Labs Sector 2 | 409 |
| 039 | Alpha Labs Sector 2 | 102 |
Read the supporting PDA
Codes are often written in email or spoken in an audio log. Listen through the relevant recording. An access code for a door is not necessarily the nearby locker code.
| Locker or cabinet | Area | Code |
|---|---|---|
| 047 | Alpha Labs Sector 3 | 123 |
| 048 | Alpha Labs Sector 3 | 123 |
| 049 | Alpha Labs Sector 3 | 123 |
| 064 | Alpha Labs Sector 4 | 651 |
| Martian Buddy cabinet | Administration | 0508 |
Keep leading zeroes where shown
The Martian Buddy cabinet uses 0508. Enter the full sequence, including its leading zero, instead of treating it as the three-digit format of ordinary lockers.
Do not mix campaign lists
Resurrection of Evil and The Lost Mission have different locations and codes. This table covers selected original DOOM 3 lockers, not every cabinet across all releases.
