You won’t be able to unlock Hogwarts Legacy doors and chests for quite some time. It isn’t until you come across the main story quest called ‘The Caretaker’s Lunar Lament’ and learn Alohomora. Here, you’ll properly meet Hogwarts’ caretaker, Gladwin Moon. He’s usually a bit of a tough geezer, but he recently has become paranoid that someone’s out to torment him. Recently he came face-to-face with a Boggart, which apparated into his greatest fear: a Demiguise. Now all of a sudden, there are statues everywhere, and he wants to reveal the identity of his assailant.
During this quest, Gladwin teaches you Alohomora, one of the Hogwarts Legacy spells, which unlocks both doors and chests, which in this open-world game can contain valuable gear and collectables. To get this precious spell, you first need to progress through the Hogwarts Legacy story for a fair number of hours until you get this main story quest in your log. Gladwin will teach the first level to you as part of the quest, but returning Hogwarts Legacy Demiguise Statues to him will eventually increase the spell’s level to a maximum of three.
