5 Creative DIY Crafts You Can Make with Old Keys

Old keys are too good to throw away. They have weight, character, and decades of patina that you can’t fake. Here are five projects that turn a drawer of forgotten keys into something you’ll actually display.

1. Vintage Key Wind Chime

There’s a specific, hauntingly beautiful music that only old metal can make. Instead of letting those retired house keys jingle aimlessly in a junk drawer, you can give them a second life as a functional instrument for your front porch. This Vintage Key Wind Chime project is all about embracing the unique, mismatched aesthetic of skeleton keys and brass tumblers to create a soulful garden accessory that sounds just as good as it looks.

Shopping List:

• metal hoop wind chime supplies
• vintage keys lot
• clear fishing line
• rustic jute twine

Steps:

1. Gather 12 to 15 keys in mixed sizes and finishes (brass, silver, iron). Lay them out and choose your final lineup.
2. Cut fishing line into pieces ranging from 6 to 12 inches so the keys hang at staggered heights.
3. Thread a piece of fishing line through the top hole of each key. Tie a tight double knot at the key, leaving the long end free.
4. Tie the free end of each line to your metal hoop, spacing the keys evenly around the circle. Heaviest keys go closer together so they collide and chime; lighter keys hang on the outside.
5. Cut three 18-inch lengths of jute twine. Tie one to the hoop at three equally spaced points (think 12, 4, and 8 o’clock).
6. Gather the three jute ends together above the hoop and knot them into a single loop for hanging.
7. Hang in a covered porch area where the wind moves but heavy rain doesn’t reach the keys directly.

Dos & Don’ts:
Do mix metal finishes for depth.
Do hang it where it can move freely.
Don’t overload it with heavy keys — the hoop will bow.
Don’t use nylon line that yellows with sun exposure.

2. Skeleton Key Wall Art

This Skeleton Key Wall Art takes those heavy, tactile pieces of the past and turns them into a sophisticated focal point for your home. By mounting mixed metals against a natural backdrop like stained wood or linen, you create a piece that feels less like a DIY project and more like a high-end gallery find.

Old keys mounted in rows on a stained wood board or linen canvas. Mix brass, silver, and iron tones for that collected-over-decades feel.

Shopping List:

• antique skeleton keys
• linen canvas boards
• wood stain set
• mounting adhesive

Steps:

1. Choose a board around 12×16 inches (small enough to be intentional, big enough to hold 9 to 12 keys).
2. Sand any rough edges, then brush on a single coat of wood stain in walnut, espresso, or weathered gray. Wipe off excess with a rag and let dry overnight.
3. Lay your keys out flat on the dry board in 3 or 4 rows. Aim for visual variety: a long skeleton key next to two stubby brass ones, a thin silver between two thick iron ones.
4. Take a phone photo of your final layout. This is your map for gluing.
5. Pick up one key at a time. Apply a small dot of mounting adhesive to the back, set it back in place, and press for 30 seconds.
6. Repeat for every key, keeping spacing consistent (about an inch between keys works well).
7. Let the board cure flat for 24 hours before hanging. Use sawtooth hangers or D-rings on the back.

Dos & Don’ts:
Do space the keys evenly across rows and columns.
Do use neutral backgrounds — stained wood or linen — so the keys are the focus.
Don’t overdecorate the wall around it. The piece is the statement.
Don’t glue before testing your layout. Once down, the adhesive doesn’t move cleanly.

3. Key Necklace Charms

These Key Necklace Charms bridge the gap between industrial grit and delicate femininity, turning a heavy piece of hardware into a wearable piece of history. Whether you pair them with soft silk ribbons or a classic silver chain, these pendants take about 15 minutes to assemble but look like they were plucked straight from an artisan boutique.

Shopping List:

• antique key charms
• jewelry pliers set
• crystal bead assortment
• ribbon necklaces

Steps:

1. Pick a key with a decorative bow (the loop end). The more ornate the bow, the better the pendant reads.
2. Wipe the key down with a soft cloth. If it’s heavily tarnished, brush on a thin coat of clear acrylic sealer to prevent the metal from leaving green marks on skin.
3. Open a small jump ring with jewelry pliers, slip it through the top hole of the key bow, and close.
4. Cut a 24-inch length of ribbon (or use a chain). Thread through the jump ring.
5. Slide 2 to 3 small crystal beads onto the ribbon above the key for accent. Tie small knots above and below the beads to hold them in place.
6. Either tie the ribbon ends in a knot or attach a clasp set with the jewelry pliers.
7. Hang it on a jewelry stand or wear immediately.

Dos & Don’ts:
Do mix materials — metal, ribbon, and beads — for texture.
Do keep proportions balanced. A heavy key needs a thicker ribbon or chain.
Don’t skip sealing the metal. Old keys oxidize and stain skin and clothing.
Don’t overcrowd the design with too many beads. Let the key carry it.

4. Key-Stamped Clay Trinket Dishes

Most people see an old key as a tool that lost its job, but in the world of ceramics, it’s a ready-made stamp with incredible detail. These Key-Stamped Clay Trinket Dishes turn those forgotten metal patterns into delicate, fossil-like impressions. It’s a project that plays with negative space and metallic finishes to create a catch-all that looks like it belongs on a high-end vanity—perfect for holding your rings, earrings, or the loose change that started this whole collection.

Shopping List:

• air dry clay
• metallic acrylic paint set
• soft bristle craft brushes
• clear acrylic sealer spray

Steps:

1. Pull a fistful of air-dry clay (about the size of a tennis ball). Knead for a minute to soften it and remove air bubbles.
2. Roll the clay flat between two sheets of parchment paper to about 1/4 inch thick.
3. Use a small bowl or jar lid (4 to 5 inches across) to score a circle in the clay. Cut along the score with a butter knife and remove the excess.
4. Press keys gently but firmly into the clay surface. Pull straight up — don’t drag — to leave a clean impression. Repeat with 4 to 6 keys, overlapping the patterns.
5. Lift the clay disc carefully and drape it over the inside of a small bowl (or a crumpled ball of foil) to give it a shallow curve. The edges will lift naturally.
6. Let dry undisturbed for 24 to 48 hours, depending on humidity. The clay will lighten in color when fully dry.
7. Lightly sand the rim and bottom with fine-grit sandpaper to smooth any rough spots.
8. Brush gold or bronze metallic paint into the key impressions. Immediately wipe the surface with a soft cloth so the paint stays in the recesses, not on the raised clay.
9. Once paint is dry (1 to 2 hours), spray two thin coats of clear acrylic sealer to lock everything in and protect from moisture.

Dos & Don’ts:
Do roll the clay to an even thickness — uneven clay cracks while drying.
Do press keys gently for clean impressions.
Don’t overpaint. Less metallic paint reads more elegant; thick paint looks costume-y.
Don’t skip sealing — air-dry clay is porous and will absorb water.
Don’t skip sanding rough edges. The rim is what your fingers touch.

5. Memory Jar Key Display

A glass jar filled with loose keys is just a junk drawer in a different container. But when you add layers of texture and handwritten context, it becomes a Memory Jar Key Display. This project turns a simple collection into a physical time capsule—a centerpiece for a bookshelf or windowsill that tells a story of the places you’ve lived and the people you’ve known. It’s less about the hardware and more about the history they unlocked.

Shopping List:

• glass apothecary jars
• lace ribbon rolls
• dried flower mix
• mini kraft tags

Steps:

1. Wash a wide-mouth glass jar (apothecary, mason, or salvaged) with soap and water. Dry completely inside and out.
2. For each key, write a small note on a kraft tag or scrap of paper: where it came from, what it opened, the year, the person it belonged to. If you don’t know, write what you imagine.
3. Roll each note into a small scroll and tie with a thin strand of jute or thread.
4. Place 2 to 3 keys at the bottom of the jar to anchor the layer.
5. Tuck a few rolled notes between the keys.
6. Add a small handful of dried flowers — lavender, baby’s breath, and small rosebuds work well.
7. Continue layering keys, notes, and flowers until the jar is two-thirds full. Don’t pack it — leave airspace so each layer reads.
8. Tie a length of lace ribbon around the jar’s neck and finish with a small bow.
9. Attach a kraft tag to the ribbon with a date or family name written in pencil.
10. Set the jar on a shelf or windowsill where light can pass through the glass.

Dos & Don’ts:
Do include handwritten memories — the notes are what make this personal instead of decorative.
Do display where light can come through the glass.
Don’t overcrowd the jar. Two-thirds full reads as collected; full reads as junk drawer.
Don’t use sharp-edged keys without filing them down — they’ll snag the lace and notes.
