Warehouse door doesn't recognize that i have the key
I am at the warehouse, i take care of the enemies as required but i aquire the warehouse key automatically and the door doesn't register that i have it and will not unlock
What do you mean by "i aquire the warehouse key automatically" ?
You're supposed to get the warehouse key by picking it up manually off the ground from the last guy you kill in that area.
Try restarting the encounter, or the chapter from the main menu.
If that doesn't work, delete and reinstall the game.
