LEGO Harry Potter: Years 1-4 Cheats

Head to the Wiseacres Wizarding Equipment in the Leaky Cauldron hub area. It can be found in Diagon Alley. You can enter the following codes upstairs for the desired effect.

Go to the room were you make the old man potion in year four and go through the door to the right. In the room their is a gate with three locks on it. In the room their are three keys. To get the keys you will need Hermione, Griphook, and a Hufflepuff student (you can also use Dumbledore). To get the first key, go near the door where their is a picture with a man in it. Wave to the picture with the Hufflepuff student or Dumbledore and he will throw you a key. You can get the second key by making Griphook turn the key on the giant snake statue. The statue will move and drop the key out of its mouth. To get the third key you need Hermione to copy the pattern on the bookshelf. Once you have put the keys into the gate it will open and show some Lego bricks. Move the bricks to make stairs (going to the left). Once your done, go up and walk to the far left. Their is an open chest with Professor Snapes character token.

There is a "dungeon" in Flitwick's Wingardium Leviosa room, under a trap door with a big shiny lock (You need Reducto to open it, which you don't get until year 4). When you jump in, you can get some loot (bring a Dark Magic user) -- but then you are seemingly trapped. THERE IS HOPE! Using Hermione, make your active spell Crookshanks. Go to the left top corner, and jump out of the window while tapping the spell button. When it works, Crookshanks will appear in the classroom, and you can walk out of the room. It takes a few tries, and you will probably kill Hermione a bunch of times, but it will work.

In order to do away with the objects with red sparkles around them you have to use dark magic. In order to use dark magic you need to use the Polyjuice Potion (or use an evil character on freeplay -- e.g. Lord Voldemort, Tom Riddle or Barty Crouch Jr.). Evil characters' Wingardium Leviosa spell is changed to the Crucio curse (but works just the same as Leviosa) and can now destroy the red sparkly objects.

Whenever Nearly Headless Nick is floating still (and you have the Ghost Stud extra on), stand under him and he'll constantly give you ghost studs.

Find, post and purchase the "Collect Ghost Studs" extra. The parcel was either in Harry's bedroom or on the courtyard fountain (You will need to have learned the Leviosa spell first). Once activated the Ghost Studs are worth 1,000 each. "Get lost" the ghost will return to you and lay more studs -- it's easy money. A full trip from the Dorm to the Great Hall is worth about 100,000.

If you purchase and use the "Christmas" extra, the room you use it in will keep playing the same music for the rest of the game... Just like the red-haired Ron cheat, it will not revert back to its regular music.

After completing the first two levels of the game, you should have enough LEGO Pieces access this Easter Egg. Go into the wizard town through the Leaky Cauldron, the last shop on the left (before the bank), sells custom spells. Purchase the spell called 'Multicorfors'(a spell that turns the characters into "gingers"). Cast it on Ron Weasley. Once cast, he will shake his head as if it has worn off, but his hair will not revert back to its natural color.

Type in the code VE9VV7 to get spell in the town to it normaly cost 4,000,000 studs
