I have been playing Legend of Zelda Classic and I've been wondering if something is wrong with it because some of the doors in the dungeons that require me to kill all the enemies arent opening.

Welcome to the forums, Legend of Link!
This is the original game you're talking about and not a user-made quest, correct? In which dungeon level/room are you getting stuck? Having you tried pushing any blocks in the room(s) after killing all the enemies?
