Hi, I'm NobleKoala. I often play Survival Minecraft, Hardcore Minecraft and occasionally play other games. I focus on survival strategies, creative building and hardcore challenges. My channel is focused on content that is entertaining and educational about the legendary blocky game that we've all grown to love.
The game dev updated the game with keys. Here is another video showing where the key locations are if you're interested :ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-eZx2biLLd9c.html
As mentioned in the pinned comment and the video title, the bug was patched by the developer. But you can watch the linked video in the pinned comment to see the other places you can find all the keys.
It's really difficult to beat the game using a wrench in Survivor Difficulty with only 3 plasmids - Electrobolt, Incinerate and Telekinesis. And having Vita Chambers disabled. Try it yourself!
