i recieved a illustrator file with thousands of layers/sublayers, one of them is locked, and illustrator don't let me replace a font because says that "layer is locked".
there is a command to unlock all layers?
or to force a replace font without unlocking?
Layers Palette Flyout Menu >> Unlock All Layers
Try locking one of your top layers. It will be available then as here
When I had no top layers locked it looked like yours.
Except the fact that it doesn't work.
Although it unlocks all layers, but won't unlock locked paths.
Object -> Unlock All
for that in the menu.
Unlocking all objects wasn't the question; unlocking all layers was.
I've tried locking a layer to get the Unlock All Layers menu item and tried that, but there are still two fonts I cant Find/Replace because I continue to get the dialog:
Maybe a corrupt file?
What are the fonts you are having trouble with?

After some research I managed recently this :
