xev doesn't record keycode of lock screen key

  • 772

I just got a lenovo ideapad 720s and installed Ubuntu. It has no media control keys (play/pause, next/prev track), so I wanted to remap some keys I don't use including the lock screen key. But when I use xev and press the key, the screen locks and the keycode is not displayed in the terminal. Is there another way to find the keycode?
