Hospital Chemical Lab: lab key, locker keys and entrance
Search the upper offices for the lab key, then return to the morgue for the separate locker keys.
Use the Hospital Chemical Lab Key at the named brown lab door near Mirae General Hospital's underground morgue. Search the upper offices for that key and the morgue-side rooms for Hospital Chemical Lockers keys. Opening the lab does not unlock its yellow lockers; bring a matching locker key for each opening you plan.
- Lab key reported on an upper-office desk
- Locker keys reported on morgue-area counters
- Lab entrance and lockers are separate locks
- No guaranteed three-key set or fixed loot
Find your key or locked room
Browse every key in the Key FinderHospital Chemical Lab has two access steps: the room door, then the chemical lockers inside. Take the lab-entry key to the underground morgue area of Mirae General Hospital, then use your locker keys at the named yellow cabinets.
Match the two key types before you go
| Item | Where it is used |
|---|---|
| Hospital Chemical Lab Key | The brown door named HOSPITAL CHEMICAL LAB |
| Hospital Chemical Lockers | A named yellow chemical locker inside the lab |
Leave backpack space for keys and the loot you intend to keep. A locker-key pickup can show BACKPACK FULL: looking at the card is not the same as taking it. Check your inventory after clearing space.
The Mirae Electrical Room and Doctor’s Command Office are different destinations. Their keys do not establish Chemical Lab access. If your item name differs, check its own destination rather than searching every hospital lock.
Enter from the south and find the main stairs
The approach starts at the hospital’s back, on the south side, near an ammo-cache reference. Enter the red corridor and keep that landmark in mind for the return. Take the right-hand passage and continue to the main staircase.
Go up through the blocked intermediate landings to the upper office level. The route identifies this as floor seven; confirm your landing and room signs before searching.
Search the upper offices for the lab key
A Rare Hospital Chemical Lab Key has been found loose on an office desk beside a monitor, lamp and papers. Read the full card name and take it before returning downstairs.
Additional reported search areas are rooms 701, 702 and 703, plus the small conference room on the same level. Check visible desks, shelving, countertops and the cabinet near the television. These are search leads, not a promise of a key on one particular desk in every match.
Once you have the actual lab key, return to the same main staircase. Repeatedly checking an empty office is not a reason to sacrifice your return time.
Return to the morgue for locker keys
Go below the first floor to the underground level and return to the red corridor. Search the adjoining morgue and medical rooms. Read Hospital Chemical Lockers on each key card; the upstairs lab-entry key opens a different lock.
Check medical counters, worktops, shelves and nearby rooms for Hospital Chemical Lockers keys. Confirm the exact name before keeping a copy for a yellow cabinet.
Check how many keys are actually in your backpack after each pickup. A blocked TAKE prompt does not mean you collected the item. There is no guaranteed three-key set; stop searching when another room would put your extraction at risk.
Open the named Chemical Lab door
Return toward the central stairs and the red corridor. On the other side of that stair area, find the storage-room approach and the brown single door in white walls. Confirm HOSPITAL CHEMICAL LAB — UNLOCK before interacting.
Use the lab-entry key to enter the room with the yellow lockers. A Hospital Chemical Lockers key does not replace it; each cabinet inside has its own lock.
Open a locker, then check what you gained
At a yellow cabinet, confirm HOSPITAL CHEMICAL LOCKERS — UNLOCK and use the matching key. Open that cabinet’s loot panel, then check your remaining keys before selecting another. Plan a separate copy for each opening.
Read the crafting-ingredient cards and keep what serves your next upgrade or recipe. No high-rarity reward, Irradiated Container or fixed loot table is guaranteed.
Leave with the useful find
Keep enough ammunition and healing for the return through the hospital. Use the central stairs and red corridor as recognition points, then check your current exfil. Check the defenders on the way out rather than assuming your entry route is still clear.
| Problem | Next check |
|---|---|
| A key is visible but not in your inventory | Clear space and confirm TAKE succeeded |
| The lab door remains locked | Match the lab-entry key, not Hospital Chemical Lockers |
| The room is open but a yellow locker is locked | Check its own prompt and your remaining locker keys |
| Another key cannot be found | Use the copies you have; protect the exit instead of relying on a guaranteed third |
