Flutes have cylindrical holes. They are usually made of metal, often silver or nickel silver obviously there are also other materials such as gold and platinum used in their construction. Adding the keys into the flute (and changing them into the flute) allowed the player to create a wider range of notes and play more complex pieces much more simply compared to older simple flutes.
