The cam locks were a pain. The screw driver's I had were not big enough to lock them and so I finished the cage without them. I am waiting for the weekend to go buy a larger screwdriver and hope that fixes the issue. Though it seems that the hole is also dug a little deep? Not sure what the issue is but I couldn't get any but one of them to lock. 

That being said, the cage is beautiful and my Chiweenie loves it. It's like a mini mansion for her.
