Actually the mute button does NOT lock the phone or the keypad, it's only a mute feature and to place the device in stand-by mode by pressing and holding the button in. You either have the choice of setting the device password or keypad lock, but you can't have both set. So if you disable the password feature, pressing the lock will lock the keypad; but if you set the password feature, it will disable the keypad lock.
