This part will only replace a missing or damaged volume button and does not typically control the functionality of the volume key. The volume button is mounted in between the back housing the chrome bezel and the bezel will need to be removed to replace it. Installation of this part will correct a cosmetic damage to the button, but will not ensure a properly functioning Volume button. If your Volume key is not functioning properly, you will need to order the HTC Volume Flex Cable to correct the problem.
