Some say romance begins when strangers catch each other's eye across a room, while others seek it out by swiping right. But new research suggests more than two-thirds of all romantic relationships begin as friendships.

I'm assuming she is the one controling the frame (more common). It's hard to make a statement that applies to every interaction a man has with a woman, but you can come out of friendzone if one or more of the following is true:
-she friendzoned you before because she had better options, options that faded away as she grew older; now she views you as someone to settle for, someone "whom she feels comfortable with" and all that sh*t (she might convince herself that this is true so don't hold a grudge);
- similar situation, but you yourself became a high valued man, she noticed it and decided to go in for the kill;
- your might not have become a high smv male, but you stopped being timid and acting like a prude around her and it made her stop perceiving you as a harmless boy.
My advice: don't ever focus on exiting the friendzone. Time better spent doing other stuff
