A door for each key
Where the doors are
Per the wiki, both doors are on the ground level, one on the south side of the building and the other on the east side. Our map marks the key's door at the southern edge of the Testing Annex compound.
Testing Annex sits south west of Red Lakes Balcony Lift, and Electrical Tower is east of Testing Annex. The base map records Testing Annex as a white zone.
What the wiki lists inside
Per the wiki, the containers are lockers, drawers and filing cabinets.
Where keys come from
The wiki lists scavenging and quests as sources. Shani's quest A Lay of the Land, set on the Spaceport, also rewards a Dam Testing Annex Key; its last objective is to deliver a LiDAR Scanner to Shani.
Bringing a second key
Since one key opens one of the doors, carrying a second key is the only way to open both in a single raid.
Doors for every other key are on every key location, and every marker named above is on the Dam Battlegrounds map.
