I made a key, and I have some problems with how to dimensions with tolerance in solidwork?

Someone who can help me with this?

I got this feedback and I really dont know how to fix it

* Your key does not meet the requirements for approval and must be supplemented.

* Dimensions required for the manufacture of your key are missing.

*Dimensions important for function control are not exposed - you must now calculate them from a non-tolerance angle.

*Functionally, the key would be very difficult to use as it does not stay in place, so you have to actively center it when using it - I mean the center pin.
