How can I reuse or recycle old house keys?

A bunch of keysI’ve had an email from Jory, asking for suggestion about what to do with “a ton of old house keys”.

We’ve got a number floating around too – not just house keys but old bike lock keys and other misc keys that are probably for something really important we just don’t know what.

So any ideas?

Best Suggestions

  • Reuse: Lots of people have suggested using them as different type of decorations and jewellery – and if you don’t want to do that, there are a number of different artists collecting them (see below).
  • Recycle: If you’d rather recycle them for charity, they’re collected by a number of charities – for example Keys For Kindness in the US.

    If anyone else has old keys they’d like to give away you can mail them to:

    4001 Meriwether Drive
    Durham, NC 27704 USA

    Any and all keys are welcome and appreciated. As few or many as you would like to donate. I am collecting keys to melt down and create other metal goods.

    an edit to the above post:
    it is 4001 Meriwether Drive #13C. Without the 13C you will be sending it to a very confused apartment complex. Haha

    Use them for coasters.

    I saw a percussionist using keys hung in a string as a percussion instrument. I am collecting keys now to try that.

    • Hel says:

      Hi.

      I am looking to build a similar instrument. I have collected 13 old keys. I’m seeking the blueprints to build them right. I get the impression that a small piece of wood, a drill with a small bit, the keys and some fishing string should do the trick, of course with proper protective wear!!! lol. So if anyone knows of a place online to get some type of blueprint or instruction on how to make these, please send me a message at heldrawsthemusic@myspace.com. Thanks.

    KEYS >>> old keys are great. Dip one in metalic paint or spray on gold or silver. Put key on a necklace. Large old time keys are best. but a small one used with other items and makes a charm bracelet. I like the small lock and key combination and put on a necklace. OK i’m a man and straight but i’m into crafts full time. Durn, i need to send photo of keys in a display case… Most old door keys bring about $2.50 each at antique stores.

    I have imbellished old pictures frames with keys. You can use old greeting cards as pictures for the frames. You can paint the keys or just leave them they way they are. Just glue they keys around the frame. You will want to place the keys around the frame before gluing for measurement. You would hate to get around the frame and not have enough room for that last key. These make great gifts.

    I totally forgot about this one idea. Christmas tree ornaments. I bet keys would make really nice ornaments. Shine them up and let them sparkle with the lights.

  10. Jaime says:

    I work at a buisness fr people with special needs. One of our participants makes artwork out of old PC’s, 3d PCI cards, and old keys. She also uses sea shells and whatever comes to her mind. If anyone has any of the materials I have listed, please email me at jmzicha@yahoo.com. She would be THRILLED!!!

    Thank you

    I have been collecting keys for as long or longer than I have been gardening. I worked for a car lot for thirty years and on a whim started collecting keys. Then started finding odd shaped ones. I have quite a few and plan to make a montage in the shape of a key, using my keys to make the design. I also collected old license metal tags. There are just so may uses for these: bird houses, purses, etc. All I need now is the time and the toola.

  12. Olia says:

    You can carry some with you to full the potential thieves, and leave them laying around, while real keys are hidden inside your pocket or a purse.

  13. Olia says:

    Make wind chimes.

  14. Olia says:

    Adorn a manly lamp shade by hanging them along the bottom.

  15. Olia says:

    Fill a cute jar or little container with them and use as paper weight.

  16. Marina says:

    Instead of keeping a brick in your toilet tank, fill a container with the old keys and submerge to save water.

  17. Olia says:

    Outline each key on a paper, and make kids find each correlating key.

  18. Olia says:

    Use old key to play guitar.

  19. Olia says:

    Form the end of an old key as screwdriver, carry it with you and use it as needed.

  20. Olia says:

    Use square part to spread glue or cocking.

  21. Olia says:

    Hang them at the corners of a table cloth when eating outside, so wind won’t blow the table cloth off the table.

  22. Olia says:

    Make a ball of clay, stick old keys all around it, then let dry. You’ll have nifty decorative item.

  23. Olia says:

    Hide them in a soil, sand or grass and practice working your metal detector.

  24. Olia says:

    Use an old key to direct a nail while hammering. Make sure the nails have heads smaller than a hall in the key.

  25. Olia says:

    Glue them to form number of your house.

  34. Josh McGill says:

    I just used a couple old keys to add extra weight to the handle mechanism on my old toilet. I usually had to jiggle the handle to get the main gasket to seal now because of the keys I am good to go.

    I took the top off the toilet and added the two keys to the top of the chain that connects the main gasket to the handle lever- then reconnected the chain with the keys to the lever.

    Thanks old keys!
