Not only does this activity entertain your little locksmith to be it also develops manual dexterity, hand-eye coordination, problem-solving and memory! That’s a lot for one simple ( and mess free) activity. My son loved it- it was challenging but not frustrating. My advice is if you think your little one is ready, try it if they get frustrated, put it away for a while, then try again.
- Gather your materials. I got three different lock/ key combos at a discount store; you want them to look different, so it’s not too confusing. I also a binder ring for a key chain and a tray to keep the activity in one place.
Put all three keys onto the ring.
Lay out the locks and key chain and invite your child to open these locks.
I helped with the first before I was shooed away by my independent 2-year-old. Let them do it themselves, and even fail. 
Only help if they ask for help.
“Look mama look! Key in!”
Some keys can be high in lead – so make sure you wash hands after playing!

Like locks and keys another great fine motor activity is lacing or stitching. This stitching block is SO much fun and perfect for schools and homes that do not have a lot of storage space.

My kiddos LOVE locks/ keys–so much fun. . .until the keys get all mixed up or lost. :*)
CJStewart says
My kids love locks and keys. Be sure to wash hands after playing with keys, though. Some have high concentrations of lead.
Allie says
Thanks!
I just added a note about the possible lead, thank you so much I never knew that!
Anissa says
You have the cutest ideas! My 3 year old will start school with us next year and I’m so using some of your ideas. TFS
I’m a homeschool mom!
Mrs. Mordecai says
What a perfect idea! My son would absolutely love this.
Danielle says
I love this. My DD is obsessed with my keys and tries to open the dorrs- she is only 20 months. I have been really worried about the lead in keys though- I wonder if I can test before I buy. haha
The Activity Mom says
Wow! I can’t wait to try this! I also think it would be a great activity for the car.

We gathered up some locks and let Gracie play this morning. She loved it! Thanks for the great idea! 🙂
Brooke Everett of be in red says
We have had this as a lesson at the preschool that I work at and I also recommend it for young children. But keep an eye on the locks. One of our most innovative four year olds snuck a lock and key onto the playground and locked his favorite toys to the fence and then lost the key.
Allie says
I’m so happy Gracie had fun!
Brooke – you just brought back memories of teaching PreK and going through cubbies at nap time . I would find all sorts of my things in them.
Katrina says
Ah! So simple….so perfect! I have locks and keys around the house. Just need to find matching sets. lol. Thanks so much for this great idea!
Ashlyn Brunson says
That is SO smart! My son likes to play with keys and walk around with them pretending to lock and unlock the playroom door. I’m sure he would LOVE this activity. Do you have any suggestions on where to find those types of locks?
The Scrapbooking housewife says
This is so brilliant! I will just have to try this with my son!! 🙂
