So, i did a little digging and im taking a educated guess, all MS / Midwest Soda keycard does not have any spawns, yet. I looked through the trucks and a few other things, whilst the doors are implemented into the map, the items, keycards, truck trailer interiors, ect, have not been implemented into the map, yet. Now i could be entirely wrong about all of the things im saying, but i just simply: A, havent found the spawn, B, looked around in F1 through everything to see whats inside of all of the trailers, and C, took an educated guess of what minimal information i have found.

f1 for free camera is best thing if you wanna explore areas that you cant enter
