After the truck is stopped and you need to pick up the key to take to the Syndicate building, I have had the key spawn: 1. In the wall of the Syndicate Building 2. Floating in the air above the city 3. Under the water beneath the bridge In this case, I was unable to pick up the key at all, since it was apparently too deep under the water to reach with Telekinesis. In the other cases I was able to get it. I had mods loaded in the previous cases, but made sure to remove all of them, and I got the result pictured above on the first attempt. (I promise, I did not throw it in the water! It spawned there.) I have also had the key spawn in its intended location, on the road where the truck stops, but in these 3 out of 5 or 6 times playing the mission, it has spawned elsewhere. It may be worth noting that it has only happened with Pierce and Shaundi as escorts, though it has spawned normally with them as well.
