View all layers, unlock them all

I'm using Ai2017 and I created four different layers, and each layer has many sub-layers to them. I disabled the view for a few of the sub-layers so I could continue editing without having a blocked view, with the intention of being able to click view for all the layers at the end. Now, my view button is no longer working, and beside each sub-layer is a grayed out lock button, even though these layers were never locked. I click the eye to see it, and the eye doesn't appear. I tried quitting and restarting the program but it still isn't working, and I can't see all my layers. How do I fix this?
