Alphabet Learning Locks
I use these alphabet locks in my pre-k class. The students love playing with them and locking the locks together for other classmates. They are durable and the color is great. A added bonus, they are cheaper than the lakeshore brand!

Engaging Montessori Toy That Keeps Kids Busy
We received this YYDeek Montessori lock‑and‑key toy as a gift, and it’s been a big hit. The design combines color and shape matching with the fun of opening and closing locks, which keeps toddlers engaged while building fine motor skills. It’s sturdy enough to handle daily play, and the pieces are sized well for little hands. The bright colors make it visually appealing, and the activities encourage problem‑solving without being frustrating. For a 3‑year‑old, it’s the perfect balance of fun and learning. Whether as a gift or for your own child, this toy adds variety to playtime while supporting early development.

Fantastic learning activity for pre-readers
This is an excellent learning toy for toddlers. My four-year-old grandson loves to find the matching key to the locks, and he is excited every time he unlocks the lock. Since he still is unable to match each letter out of the possible 26 matches, I started out by presenting a choice of two, then three. He is now able to match upper/lower case letters from a field of four. I plan to buy a set to give to his daycare teacher.

Great learning toy
Great learning toy. I would recommend this - however, some of the keys are hard for a toddler to get into the lock. Also, some of the locks are difficult to close.

The keys unlock multiple letters VERY CHEAP
I was excited to do this with my daughter they have a similar alphabet lock & key set. But when we were playing we quickly realized that the keys can unlock more than just the matching lock. She was unlocking letters that didn’t match at all. Very disappointed, kind of ruins the whole point of this product if it’s poorly made & cheaply designed by having only a few 4 lock types & 4 key types for 27 letters.
