Buenas tardes, estoy jugando y actualmente me encuentro en el complejo militar. Despejamos varias zonas y teniamos dos llaves para abrir sectores. Llave 1D y 2C del complejo militar, sin embargo a la hora de abrir las puertas no nos deja y no entendemos el por que.

Good afternoon, I'm currently playing and I'm at the military complex. We've cleared several areas and had two keys to unlock certain sectors: Key 1D and 2C of the military complex. However, when we try to open the doors, it doesn't let us, and we don't understand why.
