You’re staring at a screen of plastic bricks. It’s 2026, and somehow, we are still obsessed with the TT Games formula. There is something fundamentally satisfying about watching Lord Voldemort explode into a shower of silver studs. But let’s be real. Nobody actually wants to spend six hours grinding for "Stud Magnet" when you could just type in a few letters and get on with your life. Using LEGO Harry Potter Years 5-7 codes isn't even really cheating at this point. It’s more like a quality-of-life patch that the developers left in for us.
I remember playing this back on the PS3. Now I’m playing it on a Steam Deck. The codes haven't changed. The magic is still there.
Most people think these codes are just for unlocking characters like Bellatrix Lestrange or Fenrir Greyback early. That’s part of it. But the real value lies in the "Extras" menu. If you aren't using the Score Multipliers, you’re basically playing the game on hard mode for no reason. Who has the time to manually collect 100 million studs for the "Knockturn Alley" achievements? Not me.
The Cheat Code System Is Kinda Weird
In most modern games, "cheats" are hidden behind paywalls or "Time Savers" in a digital storefront. LEGO games are a relic of a better era. To use LEGO Harry Potter Years 5-7 codes, you have to actually find the Wiseacre’s Wizarding Supplies shop in Diagon Alley. It's upstairs. You walk up to the chalkboard, and you type them in. It feels tactile. It feels like you’re actually doing something sneaky in the wizarding world.
Wait, there’s a catch.
Some codes don’t "stick" between sessions. If you unlock a character, they stay unlocked. If you activate a red brick extra—like "Fast Magic"—you often have to go back into the pause menu and toggle it to "On" every time you reload your save file. It’s a quirk of the engine. It’s annoying, but it’s the price we pay for infinite power.
Character Codes You Actually Need
Let’s talk characters. Honestly, most of the characters in this game are just reskins of the same five or six ability types. You need a Dark Wizard. You need a Strong Character. You need a Goblin.
If you’re trying to 100% the game, you’ll hit a wall where you need a character with "Dark Magic" to open those sparkling red-and-black chests. Usually, you have to wait until you finish the story to unlock someone like Voldemort or Tom Riddle. Or, you just use a code.

- BMB737: This gives you Lord Voldemort. It’s the ultimate shortcut. Having the Dark Lord available in Year 5 makes the Free Play levels a breeze.
- 2382QC: This unlocks Amycus Carrow. Why him? Because he’s a Dark Wizard you can get instantly if you don't want to play as the main villain yet.
- 67VBNV: Fenrir Greyback. You need a werewolf for certain strength puzzles. He’s the most efficient one to have in your roster.
- H8X69Y: Bellatrix Lestrange. She’s arguably the best combat character in the game because her spellcasting animation is slightly faster than others.
Don’t bother with the codes for characters like "Madam Rosmerta" unless you’re a completionist who hates walking ten feet to find their character token in the world. Stick to the ones that provide utility.
Red Brick Extras and the Stud Economy
The stud economy in LEGO Harry Potter Years 5-7 is broken. In a good way. In the early game, you’re struggling to buy a single gold brick. By the end, if you’ve used the multipliers, you have more money than the Malfoys.
The most important LEGO Harry Potter Years 5-7 codes are the ones that affect your "Extras." If you use the Score x2 code (74Y6VN), every stud you pick up is doubled. But here’s the trick: multipliers stack. If you find the x4, x6, x8, and x10 bricks in the game, and you have the x2 code active, you end up with a x3840 multiplier. One blue stud becomes worth nearly 40,000. It's ridiculous.
Essential Utility Codes
- 74Y6VN: Score x2. Get this immediately. No excuses.
- J3WHNK: Extra Hearts. It makes you harder to kill, which is great for the more frustrating platforming sections in the Department of Mysteries.
- ZK6763: Score x6. This is usually the "sweet spot" for people who want to unlock things quickly but don't want to break the game’s challenge entirely.
What Most People Get Wrong About 100% Completion
I see this all the time on forums like Reddit or GameFAQs. Players think that entering a code disables trophies or achievements.
It doesn't.
TT Games has always been cool about this. You can enter every single code listed here and still get the Platinum trophy or the 1,000 Gamerscore. The only thing that can "break" your save is a rare glitch where a character token doesn't appear because you already unlocked them via a code, but even that was mostly patched out in the Harry Potter Collection remaster.
If you’re playing on the Switch or the newer PS4/PS5 versions, you’re safe. Use the codes. Save your thumbs.

The Secret to Finding the Remaining Bricks
Even with codes, you still have to play the game. Codes won't find the "Student in Peril" for you. They won't solve the intricate Ravenclaw common room puzzles. What they do is remove the friction.
A lot of players get stuck in Year 7, Part 2. The levels get darker, the puzzles get a bit more abstract, and the "hub" world of Hogwarts is replaced by the wilderness camps. This is where "Detectors" come in handy.
There are codes for these, too.
- HA79V8: Character Token Detector. This puts a white arrow on your screen pointing to hidden tokens.
- 7AD7HE: Red Brick Detector. This is how you find the rest of the multipliers without looking up a Wiki every five minutes.
The Nuance of "Ghost Studs"
There’s a specific code for "collect ghost studs" (2FLY6B). This one is weird. In the game, Nearly Headless Nick leaves a trail of ghost studs to show you where to go next. Normally, these are worthless. If you use the code, they give you 1,000 studs each.
It sounds great, but it can actually be distracting. It clutters the screen. If you’re a new player, maybe skip this one so you can actually see the beautiful environment design. If you’re on your third playthrough and just want to buy every spell in the shop, go for it.
Why This Game Still Holds Up
LEGO Harry Potter Years 5-7 covers the heaviest parts of the franchise. Order of the Phoenix through Deathly Hallows. It’s a lot of ground to cover. The game manages to balance the grim tone of the movies with that classic LEGO slapstick humor.
Seeing a LEGO version of the duel between Dumbledore and Voldemort is still a highlight of the series. The codes just let you experience those moments without the baggage of "stud farming." They let you focus on the exploration. Hogwarts in this game is massive. It’s arguably the best version of the castle ever put into a video game, even including Hogwarts Legacy, because it feels so dense with secrets.

Limitations of the Code System
You can't "cheat" your way out of everything.
- Gold Bricks: There is no code for Gold Bricks. You have to earn all 200 of them by playing levels, finishing minigames, and finding them in the hub.
- Crest Pieces: You still have to find the four house crests in every level.
- True Wizard Status: Even with a x10 multiplier, you still have to actually pick up one stud in a level to trigger the "True Wizard" meter. It doesn't just give it to you for starting the stage.
Practical Steps for Your Playthrough
If you’re just starting a new save, here is the most efficient way to use these tools.
First, play through the first two levels of Year 5 normally. Don't worry about secrets. Just get to Diagon Alley. Once you have control of Harry in the hub world, go straight to Wiseacre’s.
Enter the Score x2 (74Y6VN) and Lord Voldemort (BMB737) codes immediately.
With Voldemort unlocked, you can go back into the early levels via Free Play and access 90% of the hidden areas right away. You won't have to keep switching characters constantly. Then, focus on finding the Red Bricks for the other multipliers. By the time you reach the Battle of Hogwarts, you’ll have a billion studs and every spell in the game.
It makes the "clean up" phase of the game—where you’re hunting for that last 1%—much more enjoyable. You aren't worried about dying or losing studs. You're just a wizard in a toy box.
Actionable Insights for 100% Runners
- Prioritize Strength: Use a code for a character like Remus Lupin (tg66r7) or Greyback early. You’ll encounter orange handles that require "strength" to pull. Without a werewolf or a potion, you’re stuck.
- The "Fall Rescue" Trick: If you find yourself falling off platforms in the Room of Requirement, use the code ZEX7MV. It prevents you from losing studs when you fall into pits. It’s a massive time saver.
- Don't Over-Code: Entering 50 codes at once can sometimes make the character selection screen a mess. Only unlock the characters you actually need for their abilities. You’ll find the rest naturally.
The beauty of this game isn't in the challenge; it's in the discovery. Using these codes doesn't ruin the experience—it just clears the path so you can see the magic more clearly. Now go to Diagon Alley, find that chalkboard, and start typing. Those studs won't collect themselves.
