The logic of the primary key is, it must contain a unique value for each row of data, so its not possible. If you try to put same PK It will throw error something like

Violation of PRIMARY KEY constraint 'PK_table'. Cannot insert duplicate key in object 'dbo.table. The duplicate key value is (aaa).
