While traversing the world as 2B, I've come across some chests that usually give some health items or crafting materials. However, not all of them are able to be opened. Specifically, I'm talking about these:
What do I need to do to open these chests?
Skins are listed as Key Items. Once you've redeemed the preorder codes for the skins, they will appear in your Key Items and you can simply equip them from there.
From this guide:
First off, bring up the game’s main menu and head over to the Items tab. Look for the Key Items option and select that. Here, you’ll find all the important items you’ve picked up over the course of the game. Select the skin that you want to equip, and then hit the Equip option. Once you do this, your Pod will assume the appearance of whatever you picked for it.
Ok, I played through again starting from scratch. The chip that shows chests (and harvest points) on the map can be had near the end of the B route play through. Immediately after I acquired it, I could see only one chest on the map. I had completed Sorting Troubles 1 already. One chest remained marked until Sorting Troubles 2 became available near the beginning of the C route play through, and then two chests appeared.
I completed that quests, and the chests were removed from the minimap. Leaving the camp though resets them so they show again, but because the quest is complete you cannot access that area again. The chests don't contain items; they are key items required to complete the two Sorting Trouble quests and seem to return when leaving the area.
Best Answer
These chests are actually impossible to open as 2B.
However, after completing the story the first time and receiving ending A, replaying the game will have you play as 9S. 9S's signature ability to hack machines comes in handy, as he can use this ability to hack locked chests that were unable to be opened while playing as 2B.
During your first playthrough, since you can't do anything with these chests, just make a quick note of where you saw them and move on.
It's worth noting that this ability opens up a lot of previously unavailable side-quests, as well, in case you felt that there was a serious lack of side-quests your first time through.
