How to Make a Brick Keychain: Minifigure Charm DIY
Short answer first: a brick keychain is one of the most likeable little crafts you can give away. It takes 10–20 standard bricks and roughly 15 minutes. The safest build is a ready-made minifigure plus a ring brick — solid and cute. If you want something more original, build a small animal, an initial letter or a mini building instead. Cost runs about 5–20 yuan, and the result carries far more thought than a store-bought keychain.
The big difference between a keychain and a display model is that it has to survive abuse — pocketed every day, swinging from a bag. So keep the structure compact, press every joint tight, and where needed thread a thin cord or a key ring through the body so that no single part can go missing.
Step 1: Pick a style and gather parts
Choose from three beginner builds:
- Minifigure version — one standard minifigure plus a ring, about 8 parts.
- Letter version — plates forming an initial, about 12 parts.
- Animal version — a mini cat or bear, about 18 parts.
The key connector is the ring brick, a special piece with a loop on top. Bought singly online it costs 1–2 yuan. If you don't have one, you can simply thread a key ring straight through a brick hole.
Step 2: Build the body
The minifigure version is the easiest: assemble the head, torso and legs, then wedge the ring brick between the head and the torso — or run the key ring directly through the stud on the minifigure's neck. The letter version needs a grid sketch first: outline the shape cell by cell with 1x1 plates, then clip a 1x2 brick across the top as the hanging point. Whichever version you pick, squeeze every seam with your fingers when you finish and check that no part is loose.
Step 3: Add the cord and reinforce it
Pass a key ring or a lobster clasp through the loop, then add a second split ring so the keychain is easy to take off. For extra security, put a tiny dot of brick glue on the internal load-bearing joints, such as the minifigure's neck. It cures in 20 minutes and after that the build practically never comes apart. Keep the glue away from visible surfaces so the finish stays clean.
Step 4: Test it, then give it away
Put the finished keychain in your bag for two days before gifting it: open and close the bag more than 10 times a day and confirm that no part falls off. Once it passes, wrap it up — birthdays, Teacher's Day and graduation season are all good occasions, and it is far more memorable than a bought gift. If you are making them in bulk, a set of 12 for classmates or coworkers is a fun project.
If you don't have a dedicated ring brick, the simplest substitute is to slip the key ring through the gap between the minifigure's neck and torso and press the two firmly together — the result is just as strong.

FAQ
Q: How do I make a brick keychain, and what do I hang it from? A: Use a ring brick (a special piece with a loop on top, 1–2 yuan each) or simply thread a key ring through a brick hole. The minifigure version is the easiest: wedge the ring between the head and the torso and you are done in 15 minutes.
Q: Will a brick keychain fall apart easily? A: A compact build with firmly pressed joints will hold up in normal use. If you are worried, add a little brick glue to the key joints, such as the minifigure's neck — it is very secure once cured for 20 minutes.
Q: Which bricks should I use — LEGO or domestic brands? A: Standard bricks from any brand are compatible. For an ordinary charm, domestic compatible bricks are fine and cost 5–10 yuan. Only special pieces such as the ring brick are worth buying from a major brand, because domestic special parts have slightly looser tolerances and the loop can pull off.
Q: Is a brick keychain a good gift? A: Very much so. For birthdays, Teacher's Day or graduation it goes down well with friends and coworkers: low cost, plenty of thought. Make 12 at once for classmates and vary the minifigure style so each one feels personal.
