I have tried to unlock the Water Lock, both the press button on side and turning it and shutting off watch, nothing has changed.

Press and hold the knob (on current versions), or quickly rotate the knob a dozen or so times (on older versions).

 If your Apple Watch has watchOS 8 or earlier, rotate the Digital Crown instead of pressing it.
