Whether you are looking for Agravaine’s Lockbox Key, trying to start the Infiltrators side quest or want the location of Agravaine’s Lockbox in Atomfall, I’ve got you covered with my guide.
While the world of Atomfall is small, it is filled with riddles and side quests that can take and progress by following certain leads.
Among them, we have Agravaine’s Lockbox associated with the Infiltrators side quest.
Even if you are not following the quest, getting the contents of the lockbox early is recommended.
Why?
Because it holds an MK. VI Revolver and the Sticky Bomb Recipe along with some bullets.
So with that said, here’s where you can find Agravaine’s Lockbox and its key in Atomfall.
Where to find Agravaine’s Lockbox Key in Atomfall

Agravaine’s Lockbox Key and the lead to start the Infiltrators side quest in Atomfall is found at the Helicopter Crash Site POI.
You can find the said POI at the following coordinates: 28.2E, 71.1N.

To get there, once you come outside of your Bunker, take the path right to the red telephone booth.

Keep following the path and you will eventually reach the Helicopter Crash Site as you can see in the above screenshot.

The location is guarded by a single outlaw.
Stick to the left side while he pees.
Use the grass to get close and takedown.

Grab his melee weapon, which is a Police Baton.
Now, head inside the crashed helicopter.

You find the dead body of Private Dagonet.

Interact with him and collect all the items he has on his body.
Including the Agraivaine’s Lockbox Key and the Coded Message.

The Coded Message is what triggers the Infiltrators side quest while also sharing the location of Agraivaine’s Lockbox location.
Where to find Agravaine’s Lockbox in Atomfall

As per the note in the Coded Message, you can find the Agraivaine’s Lockbox inside the locked cabin at the Slatten Dale Railyard.

The entire area is infested with Outlaws.
You can either sneak to the cabin’s location or take the enemies out and proceed.
[If you want to take the latter path, I would highly recommend checking out my Atomfall early weapon locations guide.]

The cabin that you see in the above screenshot is where you find Agraivaine’s Lockbox.
But the problem is, the door to the cabin is barred and cannot be opened.

So make your way to the other side and you will find a shutter door with an opening. \
Crawl through.

On the table, you will find Agraivaine’s Lockbox.

Use the obtained key to open the lockbox and collect the following items:
- MK. VI Revolver (Rusty)
- Pistol Ammo x6
- Sticky Bomb Recipe

To progress the Infiltrator side quest, collect and read the note ‘Orders From Agravaine’ found on the right.
