The Spaceport Trench Tower Key is one of the many keys you can find randomly in ARC Raiders.
As usual, though, figuring out where exactly you need to go to use the key can be a bit of a pain. Its name does tell you more or less where to go, that said. But it wouldn’t hurt if it were a bit more specific…
In this quick guide, we’ll tell you exactly where to go to use the Spaceport Trench Tower Key!
Where to Use the Spaceport Trench Tower Key | ARC Raiders

To use the Spaceport Trench Tower Key, you need to go to the Trench Towers on the northern part of the Spaceport map. It doesn’t matter whether you go to the south or the north tower.
Uniquely, this key can actually open more than just one door! It can open all 4 doors that allow you to enter each of the Trench Towers.

There’s one door on each side of each Trench Tower. You can see an example above, using the western entrance to the Northern Trench Tower.
You’ll have to pick which side you want to enter from, though it doesn’t make much of a difference. Do remember, though, keys are consumables! You’ll only be able to open a single entrance with 1 key.

Now, if you haven’t actually found this key yet, well… we wish you good luck! Like other keys, the Spaceport Trench Tower Key does not have a set spawn location.
Instead, it can spawn randomly whenever you search containers, primarily in Residential areas. So, if you want to get it, go to any area marked as Residential and loot everything you can! Drawers, cabinets, boxes, everything. With luck, you’ll find it.
Nonetheless, that’s all you need to know to use the Spaceport Trench Tower Key in ARC Raiders! Simply put, go to either Trench Tower in the Spaceport map and open them right up. Happy looting, Raider.
