Here is some information you all may find useful if needing to replace the volume button assembly on your HTC One M8. The volume buttons flex cable is actually part of the SDcard reader assembly. So i have linked the part here for your reference: http://www.etradesupply.com/htc-one-m8-s...
The bad thing is the SDcard reader is only accessible by actually removing the display assembly from the mid-frame. You then will need to peel back the top right corner of the thin black foam layer to access the SDcard reader. You can then loosen all areas of the Sdcard reader/Volume assembly that are held in place with adhesive and remove the part and replace in reverse order. I was nice and took some photos of some damaged spare parts from a HTC One M8 I have, so you can get an idea of what you are up against. If you need help removing the back cover and display then head to this page for guides to assist you in that process: HTC One M8 Repair
Here are some photos that show where the SDcard is located in the mid-frame and where the flex cables run through. Hope this helps you out, and good luck.

If the case is dented you could try to straiten out the dent in the case or replace it to get the volume buttons to move freely again. If the actual volume button rocker is badly bent you can replace that by removing the case to get access to it. If the volume button rocker moves freely in both directions you can also remove the volume button rocker without removing the back case. I use an razor blade or tweezers and pry up at the bottom side of the volume - down button. It has to be done from the volume down area only as it has a flexible rubber piece which slides into the case. The top side of the volume rocker is not flexible. So when putting the rocker back in, slide the bottom flexible rubber in first but not all the way back in, then lift the bottom of the volume rocker up enough to clear the case and slightly slide it back till the top of the volume rocker can drop and slide into place inside the case. Then press the bottom area of the rocker down into place once it is lined up properly.
^ thanks for this - allowed me to replace mine without having to open the case
