In Crimson Desert, in Chapter 4 during Main Quest: Gate to the Otherworld, you get the objective to activate the lock device switch underground. The minimap arrow will point below you underground.

You must go to the north-east corner of the plaza where the objective started. Follow the path with the lanterns, it leads underground.

Then interact with the “hatch”, it looks like a wall panel.

Here you must solve a puzzle by pushing the hatch buttons. You can press Dpad Left/Right to change which button to press. There are many solutions but an easy method is to press the 4 corner buttons, then press the middle button.
