Reset to standard settings to unlock

I’ve modified one line of code in my component and now the settings are locked (the settings pane displays the following message for that component: “Reset to standard settings to unlock”). I’ve gone back in and changed that line back to what it used to be but the settings are still locked. How do I get back to standard settings for this component?

I found it. There is a “Reset component” button that appears at the bottom of the settings pane in this situaiton.
