A job well done gets well rewarded. From the documents we've learned that Artyom lived in room 328. I presume, he worked there as well. Find a way to get into his room and if there’s anything left of his records, bring it to me. I'm waiting to hear from you, mercenary.
This quest item can only be found if the quest is active. When picked up, this item is transferred to the player's quest item inventory. If the player does not plant the item and fails to extract with it, they will lose it.
*Both keys give you access to East room 328, so only one of the two keys is required.
