But things can get easier if you know about the Sons of the Forest keycard map locations. With these keycards, you can enter the locked bunkers with ease and explore these bunkers to get useful items like weapons and resources.
Where to find Keycards in Sons of the Forest
You will find three keycards scattered around the map. Follow the sequence mentioned below because to get the card, you are required to have the previous card.
Maintenance Keycard
Travel to the keycard location as shown on the Sons of the Forest map. It will be on the northwest side of the Island. Approach the golf cart ahead and start digging the ground near it. Use the shovel in your inventory to dig. As you shovel, you will see a bunker (Maintenance A).
If you do not have the shovel, We suggest you get it first. It will be in the snow mountain cave, in the western part of the area.
Clear out the dirt over the bunker and try to open it. It would take a few tries to unclick it. Climb down the bunker via the ladder. Equip the flashlight via inventory; get it first if you do not have it. It will be at the helicopter crash site deep into the forest.
Start walking forward, and you will notice a room on your left after some time. Enter this room, and you will see a laptop ahead on the table. Go near it, and you will see a keycard beside it. Press E to pick it up.
