Razer Wolverine Ultimate Quick Control Panel Buttons Stuck

The mute and volume buttons on the quick control panel are totally stuck. The other two buttons are fine. I didn't spill anything on them but since a few days ago there is no travel to them at all. If I press hard enough in the right spot I can get the mute button to work, but I'd rather not have to smash on it a bunch of times for it to function. I'd rather not take the controller apart. Is there anything else I can do?
