go directly to the skywatch, where the servator boss is. there are 3 spawn locations, you can just sit near the cliff and see all 3 spots for when it spawns in 7 to 10 min between spawns. there are 4 chest locations all in a line if you drove straight you would hit each location. one is outside the lunar complex by the cliff side on the other side of a fence, the next is north of it up the hill a little behind a small building. the next is just on the other side of that building in front of an old big truck. the last one is on top of the building with the hole on the roof, which is also just next to a possible spawn point for the servator. once you get the hang of where to look for the chests just ride your sparrow into the lunar complex until it says you are in the lunar complex and turn right around asap and make your way back to the chest to loot it again and again. you can loot the chest as long as the key is still active and as long as you keep zoning out and back in, hence riding to the lunar complex. as long as the chest isnt atop the roof which is the farthest from the lunar complex you will get 3 to 4 loots per chest, and about only 2 from the top of the roof location unless you go to the forgotten shores entance, 3 to 4 from there. (thank you for informing me, SORxpiglet t33) happy hunting, hope this helps. so far ive gotten 6 keys, a legendary engram for each possible slot and way way too many blue engrams lol, and almost 500 spinmetal. Edit: i realize i am not the best at explaining the chest locations, but if you are doing it as you read, it becomes a little easier to find them. if you cant really follow along what i said and you just find them all at least once, you will see that it's super easy to get to each location the public event will spawn a ton too. i usually sit on the rock close to a spawn location almost right next to where the event lands, sometimes it almost kills me, but it doesnt... you just go flying a bit lol if anyone thinks this is "dumb" for posting, don't forget that bungie has game logs of what everyone is doing, they don't need forums to figure it out, QQ
