How much will it cost to fix accidental damage. on 2009 Toyota RAV4

Yesterday a friend of mine was messing around on the dashboard and pushed in one of the dials. The temperature control button is now pushed in and cannot be pulled out. How much would it cost to fix this roughly?

Is this Toyota still under warranty because this might be covered under your 3 year 36,000 mile warranty call the dealer and ask, because that button should last for years
