Locations

Door	Location
Sohn District, Pattern A	Start from the Sohn District Control Center breach. Go to the boss arena nearby and then turn left. At the next crossroads just continue straight forward.
Sohn District, Pattern B	Start from the Sohn District Control Center breach. Go to the boss arena nearby and then continue straight forward. Taking the ladder/zipper there will take you to a path that will lead you to the golden door. After the first drop just keep going forward or up and don't take the second drop to where the ministry key is.
Alma Mater Atrium (Pattern C)	Start from the Alma Mater Atrium Union Park breach. Go to the boss arena nearby and then continue straight forward. On the left wall you'll find the cabaret door; going through you will find an elevator that takes you to the golden door. Alternativaly, if you find the enemies there too annoying, you can start from the Ikari Walkways Chashed Tram breach. Go to the boss arena and then take the upstairs path. It will take you to an Alma Mater Atrium one-way entrance that is right next to the golden door elevator.
Ikari Walkways (Pattern D)	Start from the Ikari Walkways Chashed Tram breach. Just cross the extended bridge (assuming that you already activated it) and the golden gate is to the right.
Embassy	Start from the Embassy Great Halls breach. Near the shortcut to the Pond breach there will be a secret door that leads to an airlock. Outside there is a path leading to the golden door.
Port Issoudun	Start from the Port Issoudun Docking Bay breach. Go down the stairs and go straigh forward. Going down the ladder/zipper near the tram will take you to a locked door. The door can only be opened by the Prodigal Spawn when he is there (after 100% data?). Once inside the golden door is near.

This guide is intended as a quick reference guide to be used while you're playing. As such it doesn't try to explain everything.
That said, let me know if there's anything wrong or if some extra information would be very convenient to include. Thanks!
