Hi. And welcome. 
Imagine I locked you in a room. It has a comfy bed, maybe a TV or some books. But you cannot leave it freely.
What would you call that room? A bedroom? Or a prison?
What would you do if I put a piece of cake on the table and left the door open? Would you eat the cake in the room, or rush outside and eat it there?
How would you feel if I locked you in that room again. And put earphones in? You'd probably cry yourself to sleep too, wouldn't you?
Do you see what I'm saying?

Fill a Kong and give her that. Repeat the above, door open, door closed and immediate open, door closed, pause, open, door closed, longer pause, open, door locked, door unlocked, door open.
If at any point she starts to whine or panic, go back a step for a few more days.

Leaving her to cry it out is teaching her to self-soothe, which can cause separation anxiety when she's older. She needs to see that being in the crate doesn't necessarily mean you're leaving her, or that she's about to be locked in.
Going back to my bedroom analogy. After I locked you in the room, would you then choose to use it yourself? Or would you be worried in case I came along and locked it?
So let her. Make it a game. Throw a treat to the end of the crate with the expectation that she will rush in, grab the treat and rush out. A bit like the foundations for Fetch. Give her her meals in the crate, but leave the door open and sit beside it. Work up to closing to the door and then immediately opening it again. Work up to locking the door, unlock, open. Then increase the length of time between closing the door and opening it again. Then work up to feeding her, closing the door and stepping away - just for a second. Then go back and open the door again. Rinse and repeat.
Fill a Kong and give her that. Repeat the above, door open, door closed and immediate open, door closed, pause, open, door closed, longer pause, open, door locked, door unlocked, door open.
If at any point she starts to whine or panic, go back a step for a few more days.
