Aerary Glyph Door Location???

[Major Trainee]

I cannot for the life of me find this locked door. I found the key in The Hatchery, but going through this entire map, even killing the boss and going back did not help. ANY help would be appreciated. BTW, I searched Google, and this did not help. Thanks. Here are a couple of pics. The first is of the complete Hatchery map, minus the one door I found that is locked. And the other is of said door. I believe that is the door that I had to get to with letting out the flood water. ANY HELP WOULD BE GREATLY APPRECIATED. Thanks.

It is not there. I will look again, for the forth time. This is so odd. I edited my OP and added two pics. The first is of the complete Hatchery map, minus the one door I found that is locked. And the other is of said door. When I go to it, it will not let me go into my inventory.
Here is another picture of where a door should be according to a Google search. I have no idea. https://drive.google.com/file/d/1IJRXv5iCUldcu0sqH2PXi5Qtjo2foKk9/view?usp=sharing

I am looking for anyone with an answer to this quandary. Please, somebody, help. Thanks.

When you're looking at that door, head left. Follow the path and you will come to a control room. Press the button to drain the water out. Turn around and go right, down the ladders and there will be an airlock door you can now enter.
Have fun!
