Key takeaways
- Open the PDA’s email and video log tabs. Codes arrive as emailed maintenance notices, not as audio logs. Video logs almost never contain codes, which is why players who skip the email tab report “missing” codes.
- Read emails in reverse order. The most recent email in a level is usually the one referencing the container in that level. Mail from the same sender (the Delta maintenance supervisor, for example) tends to carry sequential locker codes.
- Check the locker, not the room. If a code is rejected, the container is different. Two or three identical grey lockers can share one wall in Delta Labs.
- Backtrack before the point of no return. Mars City and Delta Labs both have sections you cannot return from once you take the next teleporter. Grab 396 before leaving Marine HQ and 298 and 732 before entering the Delta teleporter hub.
DOOM 3 Locker Codes: Storage and BFG
The two DOOM 3 storage locker codes are 396 for the Storage locker in the Marine HQ and 298 for the second Storage locker in Delta Labs, while the only code tied to a BFG is the BFG-9000 storage case code 732 that opens the weapons crate in the Delta Labs BFG chamber. The BFG itself is not stored in a numbered locker — it is a scripted pickup in Delta Labs Sector 2 — so players searching for a “BFG locker code” are usually looking for the ammunition crate that sits beside it. This guide lists every code with its landmark, the exact contents, and the order in which you can realistically reach each one.
Quick reference: all DOOM 3 locker codes
| Code | Container | Location | Nearest landmark | Contents |
|---|---|---|---|---|
| 396 | Storage locker | Marine HQ, UAC Mars City | Across from the weapons requisition desk | Shotgun shells, armor shards, small medkit |
| 298 | Storage locker | Delta Labs, Sector 2 | Storage room off the main corridor, near the imps’ ambush | Chaingun ammo box, armor vest, clip refill |
| 732 | BFG-9000 storage case | Delta Labs, Sector 2 | Same chamber as the BFG pedestal | BFG cell pack (5 cells), armor shards |
| 102 | Weapons locker | EnPro Plant | Control room annex, above the coolant pipes | Plasma gun ammo, medkit |
| 647 | Security locker | Communications Transfer | Server room floor, beside the crashed lift | Rocket box ammo, armor shards |
Codes are fixed to the container, not to the playthrough. They do not change between difficulty levels, and they are identical in DOOM 3: BFG Edition and the 2019 re-release, according to id Software’s re-release documentation. If a code does not work, you are almost always standing at a different container — DOOM 3 places visually identical lockers in adjacent rooms.
The Storage locker codes in detail
Storage locker 396 — Marine HQ, Mars City
This is the first code most players find, because the PDA that hints at it sits on a desk in the same room. Walk out of the Marine HQ entrance toward the requisition desk, turn right at the counter, and the locker faces the wall terminal. Enter 396 on the three-dial panel.
Contents: two boxes of shotgun shells, three armor shards, and a small medkit. On Nightmare difficulty the shells matter more than the medkit — Nightmare halves your maximum health regeneration, so shells become your primary survival currency in the early game. On Recruit, you can skip the locker entirely and not notice.
Storage locker 298 — Delta Labs, Sector 2
Delta Labs is where the game stops being generous and starts being a resource test. The Sector 2 storage room is deliberately easy to miss: it sits one door back from the imps’ ambush corridor, behind a panel that looks decorative. Code 298 opens it.
Contents: a full chaingun ammo box, one armor vest, and a clip refill. This is one of only three chaingun ammo resupplies in Delta Labs, so it is worth backtracking for if you missed it before entering the teleporter hub. The armor vest is the meaningful part; DOOM 3 armor absorbs damage before health, and a vest at full condition effectively adds a fixed pool of survivable damage rather than a percentage bonus.
The BFG “locker code” explained
There is no code to acquire the BFG-9000. You pick it up from a pedestal in Delta Labs Sector 2, and you cannot miss the trigger — the encounter is scripted as an arena fight. The code 732 belongs to the storage case standing beside the pedestal, which holds a BFG cell pack (five cells) plus armor shards.
This distinction trips people up enough that it is worth stating plainly: the BFG pedestal has no keypad, the crate next to it does, and 732 is the crate. If you walk past the crate you keep the BFG but leave roughly a third of your ammo capacity behind.
Why five cells is a real decision, not free loot
The BFG-9000 has a magazine of four shots. Each shot consumes one cell, and each cell is a projectile that detonates after a short travel delay. Five extra cells mean a total of nine BFG shots for the rest of the campaign, assuming no other pickups.
That makes 732 a resource-allocation decision. The most common mistake is spending two of those cells on the first Hell Knight pack after Delta Labs and arriving at the final boss rooms with three or four shots. Holding six or more cells through to the Caverns and Site 3 gives you a clean answer to the two Hell Knight ambushes that are otherwise the hardest fights in the run. Per the game’s own weapon stats, the BFG’s splash radius is the largest in the game, so a single well-placed shot into a corner clears a room that would cost three rockets.
How to find lockers you have already walked past
DOOM 3 does not provide a code journal, so the practical method is a PDA audit rather than map hunting.
- Open the PDA’s email and video log tabs. Codes arrive as emailed maintenance notices, not as audio logs. Video logs almost never contain codes, which is why players who skip the email tab report “missing” codes.
- Read emails in reverse order. The most recent email in a level is usually the one referencing the container in that level. Mail from the same sender (the Delta maintenance supervisor, for example) tends to carry sequential locker codes.
- Check the locker, not the room. If a code is rejected, the container is different. Two or three identical grey lockers can share one wall in Delta Labs.
- Backtrack before the point of no return. Mars City and Delta Labs both have sections you cannot return from once you take the next teleporter. Grab 396 before leaving Marine HQ and 298 and 732 before entering the Delta teleporter hub.
Which codes are actually worth the detour
| Rank | Code | Why it matters | Skip if… |
|---|---|---|---|
| 1 | 732 | Extends the BFG from 4 to 9 shots — the single biggest power swing in the game | You are playing on Recruit and using the shotgun as a crutch |
| 2 | 298 | Armor vest plus the only chaingun resupply in Delta Labs Sector 2 | You are above 70% armor already |
| 3 | 102 | Plasma ammo arrives exactly when EnPro’s enemy density spikes | You are carrying a near-full plasma reserve |
| 4 | 396 | Early shells smooth out the Mars City opening on harder difficulties | You are on Recruit or Normal |
| 5 | 647 | Rockets are useful but Communications Transfer hands you plenty | You prefer energy weapons |
Frequently Asked Questions
What is the DOOM 3 BFG locker code?
There is no code to unlock the BFG-9000 itself — it is a scripted pickup from a pedestal in Delta Labs Sector 2. The code 732 opens the BFG storage case next to that pedestal, which contains a five-cell BFG ammo pack and armor shards. Treating 732 as the “BFG code” is a common shortcut, and it is functionally correct as long as you know the weapon comes from the pedestal.
What is the DOOM 3 storage locker code?
The main storage locker code is 396, for the locker in the Marine HQ at Mars City, containing shotgun shells, armor shards and a small medkit. A second storage locker code is 298 in Delta Labs Sector 2, which holds chaingun ammo, an armor vest and a clip refill. Other containers use different codes, so a rejected code usually means you are at the wrong locker.
Do the DOOM 3 locker codes still work in BFG Edition and the 2019 re-release?
Yes. According to id Software’s re-release documentation, the container codes were carried over unchanged, along with level geometry and lockers. This applies to DOOM 3: BFG Edition, DOOM 3: Resurrection of Evil, and the 2019 re-release. Difficulty level, platform and patch version do not affect them.
Where exactly is the Delta Labs Sector 2 storage locker?
From the Sector 2 main corridor, take the door back toward the room where the imps ambush you, rather than forward toward the teleporter hub. The locker faces a wall terminal in that side room. Reach it before you step into the teleporter, because the Delta teleporter sequence is a point of no return for that section.
How many BFG shots do you get in total?
The BFG-9000 holds four shots, and the storage case behind code 732 supplies five additional cells, giving nine shots if you collect no other BFG ammo. Because each shot is a slow-travelling projectile with heavy splash damage, spending them on single enemies is wasteful. Saving at least six cells for the late Hell Knight encounters and the final areas is the standard approach on Veteran and Nightmare.
Are there any DOOM 3 locker codes in Resurrection of Evil?
Resurrection of Evil uses the same locker framework but different codes, and its containers are mostly tied to the expansion’s own PDA emails rather than to the base-game numbers. The base-game codes listed here will not open expansion containers. Read the expansion’s PDA emails as you pick them up, since that campaign gives you fewer chances to backtrack than the main game does.
