Dorm Room 206 Key in Escape from Tarkov: Where It Opens and What It Is For

On Customs, the dorm room 206 key unlocks a second-floor room in the smaller, two-story dorm building. The room holds a hidden stash of drinking water, and the key is a required item for the Therapist task "Operation Aquarius".

The details come from the official Escape from Tarkov wiki (key page edited 9 August 2026, task page 27 October 2026), read on 2 November 2026. Room 206 is not in the large three-story dorms: the wiki puts it in the two-story building, whose room keys are 104, 105, 110, 114 and 206.

How to get the key

• Barter. Therapist sells it at loyalty level 1 for 7 Piles of meds. That is the dependable route, since the other sources are random.
• Loot. The wiki lists jackets, drawers and Scav pockets or bags.

What is behind the door

The wiki lists six drinks, tucked between boxes and in or on wooden crates: a Bottle of water (0.6L), an Aquamari water bottle with filter, a Water filter, a Canister with purified water, a Bottle of YMXC water and an Emergency Water Ration. Outside the task, the Water filter is the consumable the Water Collector needs at level 3.

Operation Aquarius

Item	Detail
Given by	Therapist, loyalty level 1
Location	Customs
Objectives	Find the water stockpile in a dorms room, then hand over 3 drinking-water items found in raid
Accepted items	Bottle of water, Aquamari bottle, Canister with purified water, Bottle of YMXC water or Emergency Water Ration
Rewards	3,000 experience, Therapist reputation +0.1, 80,000 roubles (84,000 and 92,000 with Intelligence Center levels 1 and 2)

The handover items must be found in raid, and five of the six items in room 206 are accepted types; the Water filter is the exception. Loot only carries the found-in-raid mark if the raid ends as Survived, so a Run-Through exit would void it (see escape time).

What changed in 1.2.0

The Customs loot pass in 1.2.0 (6 October 2026) covered locked dorm rooms in general. The wiki's drink list for room 206 was written before it, so expect it to be a minimum rather than a complete list.

Compared with key 214

Key 214 opens a room in the three-story building that holds a safe and ammo and is not a quest key. Key 206 is the opposite in purpose: it has a quest, a trader barter and a short, specific loot list. The 214 key page covers the other building.

Tips

1. Buy the key from Therapist if you have the Piles of meds, rather than waiting for a spawn.
2. Extract with the water as a survivor. The handover needs 3 found-in-raid items, and a Run-Through or MIA ending removes the status.
3. Keys fit in a Key tool, Document case or SICC case, which saves inventory space.
