Where is sprite component?

Hi, I’ve sorted issue out now. However, I’m trying to implement a door lock into my scene. Blueprint communication was briefly discussed by my tutor, but I’m still very confused.

This was tutorial that I just followed. I want it so player can’t open door when using a key function, but can open door only when activated switch. I still want whole implementation of key function though. Would you be able to help me out with is? Any help will be appreciated. :slight_smile:
