✅ How does dictionary.ContainsKey() work?

i have a class that implements IEquatable and ICompareable (i think only iequatable is needed for this but i could do both so i did), yet when I try and use it as a key it doesn't seem to work.

here is a pretty much what I have, tho i can send the actual code if needed

ItemType item1 = ...
ItemType item2 = ...

var dict = new Dictionary<ItemType, int>();
dict.Add(item1, 3); // doesnt matter what the value is rn

console.write(item1.Equals(item2)); // returns true
console.write(dict.ContainsKey(item2)); // returns false???

ItemType item1 = ...
ItemType item2 = ...

var dict = new Dictionary<ItemType, int>();
dict.Add(item1, 3); // doesnt matter what the value is rn

console.write(item1.Equals(item2)); // returns true
console.write(dict.ContainsKey(item2)); // returns false???

what else do I need to do to make this function?
