Unlock/power button

[CM97]

My unlock button is acting as my volume up button and my volume up button isn't doing anything at all. My volume down buttons is working fine. I haven't dropped or damaged my phone, does anyone know why this is happening and is there any way of fixing it? This might also mean that il be unable to turn on my phone if it dies?

if your phone has a protective case, you might want to remove it, perhaps that's causing the problem, if that's not the case, then you will have to contact Sony directly to get it inspected.
