Trying to open the door in Sacrium - I honestly do not believe it's possible to open it regardless of how fast you are. You are frozen and the first time you can move, you can already see the lock closing. I also had a crap time getting keys to drop off Fomors. Luckily someone was in zone and was willing to help open the door for me. I advise it honestly just take someone who already did the mission.
The trick is induced lag. Unplug your ethernet cable, hit the first switch, run to the second switch, plug back in, hit the second switch. First switch got sent when you plugged back in, second is hit right away. No problem.
Unfortunately, this trick only works with the Aqueducts and NOT the key trades in Sacrarium. The instant you reconnect after trading the Coral key you are frozen and it completely ignores any trades done afterwards. Judging by your wording, you're mistaking them for one and the same (since you mention running, and no running is required in Sacrarium as both keys go in the same door).
Sorry for the minor necro, but I thought it was worth mentioning as I spent ages trying to solo it using this method and broke countless keys in the process.
tl;dr Sacrarium is not soloable.
