How to complete the quest?
To complete the quest you will need the "Rusty Bloody Key". You can find it in the Klimov Mall ("Торговый дом Климова"). The key is only for this quest and one-time use. Spawn chance is less than 100%. Appears on the tool stand under the inscription "Keys" ("Ключи"). Should be hanging near the hammer. According to some information, the key cannot be placed into secure container, so it is better to do everything in one raid.
