I have used this type of case in the past, I haven't had any issues with the volume or lock buttons. The only issue I ever had is that sometimes the area that covers the camera button is not hollowed out enough to clear the camera button and may cause it to be pressed in slightly. It created some strange problems with typing numbers or symbols because of creating an unexpected interaction with the alt key. Not every case like this has been a problem, but I have had a couple that were.
