SetActive Not Working on Deactivated Objects and Imput.GetKeyDown isnt working either

I have some script that is supposed to make map sections unlocked when I press n. Then, if I press m, the map will come up, if active. For some reason, my input.getkeydown for the letter n to make the parts active does not work. T$$anonymous$$s is because the gameobjects are inactive. Is there a way I can do t$$anonymous$$s simply?
