Far Cry 6 Gran Roca Telecom Station is a Military Target and an FND Base youβll have to liberate if you want to remove Castilloβs presence in El Este Region. Additionally, youβll want to visit this location to get your hands on the Far Cry 6 Gran Roca Telecom Station FND Chest weβll discuss below.
This particular chest requires the Medical Building Keycard, which is relatively easy to find; however, if you need help, Iβll tell you where it is.
Gran Roca Telecom Station Chest Location
In Ubisoftβs video game, Gran Roca Telecom Station is in Sierra Perdida, on top of Mount Liani. You can see its location on the following map.

To secure this base for Libertad, youβll need to find and protect a hostage while dealing with Castilloβs soldiers in the process. This base can be approached in various ways, but obviously, the best way is to remain hidden. While looking around, youβll also want to spot the Biovida Lab in my screenshot. As you can see, it has a locked door, which requires the Medical Building Keycard.

Where To Find the Gran Roca Telecom Station Medical Building Keycard
To get the Gran Roca Telecom Station Medical Building Keycard in Far Cry 6, you can opt to:
- Rescue the hostage in this camp, then deal with the soldiers to get the key automatically
- Or find it by yourself
While the first option is straightforward if you want to find the key yourself, look for it inside the telecom tower. As you enter the front door, head right, and after you follow the stairs, youβll see a lot of monitors on the right side. The key (pictured) sits on a white control panel.

After you get the key, head outside and enter the Medical Building through the door in front of you. The FND Chest is on the ground by a table. Get it, then focus on the one inside the Santo Gusto Coffee Factory Storage Building.
