Looks like Encanto key is still available, so you should be able to get both Encanto key (code ENCANTO) and Eternals key (code ETERNALS) if you have $50+ in your bag. I haven't tried this myself, but that is what I have read
We have the key to ensuring you all have a wonderful holiday with this special advent calendar. In fact we have 12 of them. The Christmas tree is decorated with 12 festive stockings that each contain a mini key with a colorful design inspired by a favorite Disney and Pixar movie.
Mighty Marvel heroes Spider-Man, Captain America, Black Panther, Captain Marvel, Baby Groot, and Rocket Raccoon celebrate the holiday season in a cool cartoon style on this collectible key featuring Disney font ''D.''
