Maintenance card location in Sons of the Forest

To get the Maintenance Keycard, you need a shovel. It belongs to Carl Planter and is located on the northwestern part of the map, marked by a green circle on your GPS Locator. You can find it south of the river that runs from the beach.

Once you have the shovel, use it to dig up the dirt in the circular area surrounded by surveying equipment. You’ll find a bunker below.

Go down the ladder and enter the first small room you see. The Maintenance Keycard is on the table to the right of the laptop. You can also use the laptop to make items in the 3D Printer beside it, like a flask to hold water.

If you leave the room and follow the corridor, you can also find the Firefighter Axe, which is the best axe for dealing damage in the game.
