How to Make Crochet Key Cover Keychain Amigurumi Step‑by‑Step Pattern

The design you’re making is inspired by the provided image and the linked YouTube video, which serves as visual inspiration for the overall look, placement of facial features, and assembly method (without copying any exact wording). In this tutorial, you’ll get a complete materials list, the step‑by‑step crochet key cover pattern, plus tips for adding a mouth opening, eyes, antennae/hair details, and finishing touches. Hence, your key cover is secure and durable.

Materials Required

Yarn in multiple colors (choose your own palette)
Example colors: green (main), black (details), orange/red (mouth), white (eyes), yellow (decorations)
Crochet hook: 2.5 mm–3.5 mm (choose a size that makes tight stitches for amigurumi)
Stitch markers
Yarn needle (tapestry needle)
Keychain ring or lobster clasp
Scissors
Stuffing (optional): only if you want a puffier 3D look

Black embroidery thread or yarn: for pupils/outline details

Optional but helpful: measuring tape, small pliers for jump rings, and a small amount of felt (if you prefer felt eyes).

4. Abbreviations & Stitches Used

ch — chain
sc — single crochet
inc — increase (2 sc in one stitch)
dec — decrease (single crochet 2 together; “invisible decrease” recommended)
sl st — slip stitch
Mr. — magic ring

Special technique (optional but useful):

Invisible decrease (dec): insert hook into front loop of next st, then front loop of the following st, yarn over and pull through, yarn over and pull through 2. Creates a smoother finish for amigurumi.

Step‑by‑Step Crochet Pattern (Amigurumi Keychain Cover)

Fit tip first: Key heads vary in size. If you can, measure your key head width. Your cover should be slightly snug so it doesn’t slip off. Use the pattern as a base, then adjust rounds as needed.

A. Base Body (Main Sleeve)

This section creates the rounded body and the sleeve that slides over the key.

Rnd 1: mr, 6 sc (6)
Rnd 2: inc x6 (12)
Rnd 3: (sc, inc) x6 (18)
Rnd 4: (sc 2, inc) x6 (24)
Rnd 5: sc around (24)
Rnd 6: sc around (24)

Now you’ll start forming the “sleeve” height:
7. Rnd 7–11: sc around (24) for 5 rounds

Try sliding it over the key head after Round 9 or 10.

If it feels too short, add 1–2 more rounds.

Optional shaping for a slightly narrower lower sleeve (helps grip):

Next round: (sc 6, dec) x3 (21)
Then sc around for 1–2 rounds (21)

Fasten off only if you’re making the mouth opening as a separate border. If you’re continuing directly, keep the yarn attached.

B. Mouth Opening (Key Slot + Contrasting Border)

You want an opening that allows the key blade to pass through. The easiest beginner method is to create a short “window” by chaining over stitches.

Make the opening round.

Find where you want the mouth opening (front center).
Opening Rnd: sc around until you reach the opening area, then:
- ch 6–10 (depends on key blade width)
- skip 6–10 sts (same number you chained)
- continue sc around to finish the round

Reinforce the opening

Next Rnd: sc around, placing sc into each chain space across the opening.

Add a contrasting mouth border (optional but cute)

Join contrast color (orange/red).
Work sl st around the opening edge only (or sc for a thicker border).

Fasten off and weave in ends.

Beginner note: If the opening is too tight, increase the chain/skip count by 1–2 stitches. If it’s too loose, reduce it.

C. Eyes (Crochet or Embroider)

You can crochet simple round eyes and stitch pupils on top.

Crochet eyes (make 2 in white)

Rnd 1: mr, 6 sc (6)
Rnd 2: inc x6 (12)
Fasten off, leave a tail for sewing.

Pupils (embroidered)

With black embroidery thread/yarn, stitch a small circle/dot pupil on each eye.
Optional: add a tiny white highlight stitch for extra “cute.”

Attach eyes

Sew eyes onto the front of the cover, positioned above the mouth opening area.

Secure tightly with several stitches (keychains get handled a lot).

D. Antennae / Hair Details (Make 2)

Choose one of these easy options:

Option 1: Simple tassel strands

Cut 3–5 short strands of yarn (same length).
Fold and pull through the top of the cover with a hook/needle.
Knot inside to secure.

Option 2: Crochet curled antennae

ch 10–18
Work 2 sc in each ch back down the chain to create a curl
Fasten off, leave a sewing tail. Make 2 and sew to the top.

E. Decorative Parts (Mini Balls / Extra Details)

These tiny pieces add personality (cheeks, buttons, little bumps, etc.).

Mini ball (make 2–4, any color)

Rnd 1: mr, 6 sc (6)
Rnd 2: inc x6 (12)
Rnd 3: sc around (12)
Rnd 4: dec x6 (6)
Fasten off, lightly stuff if desired, close, and sew in place.

You can place these on the sides, near the mouth, or as “cheek dots.”

F. Assembly (Sew + Keychain Attachment)

Sew on eyes and embroider pupils (if not done already).
Attach antennae/hair securely at the top.
Sew on decorative mini balls (optional).
Weave in all ends firmly, and run tails through multiple stitches in different directions.

Attach the keychain ring.

Thread yarn through the top center of the cover (or through a reinforced side stitch).

Loop through the keychain ring and tie strong knots.
Weave the ends back inside the fabric for security.

Durability tip: If you have a small metal jump ring, pass it through 2–3 stitches at the top so it doesn’t tear through one stitch over time.

Important Notes & Tips

Keep tension even: tight, consistent stitches make the cover sturdy and neat.
Use a stitch marker: it’s the easiest way to track rounds and avoid accidental increases.

Light stuffing (optional): a little goes a long way;y overstuffing can distort the opening.
Weave in ends tightly: key covers get pulled, twisted, and handled daily.
If you’re new to amigurumi, practice Mr. sc in the round, inc, dec on a small swatch first.

Beginner Friendly Advice

Use lighter yarn colors (at least for the main body) so you can see each stitch clearly.
Go slowly at the round where you create the mouth opening, counting carefully.
Keep the image/video nearby for visual reference on eye placement and overall proportions.

If your cover is too loose on the key, switch to a smaller hook or crochet fewer rounds of increases.
