In Nancy Drew: Shadow at the Water’s Edge, you will need to unlock the light lock, known as the Krolmeister Key 3000. It is located on the wall behind the desk in the lobby. The lock is missing one colored card key.
Acquire the key to the Cultural Room (room 18) and change the time to 1am or when Takae is not in the room. Use the key to let yourself in, and you will find the missing color card on the floor.
To solve the Krolmeister Key 3000 safe, follow the instructions provided. Place the five colored cards in the slots so that the colored light tetris-like shapes are stacked. The furthest left slot is the bottom of the stack, while the furthest slot on the right is the top-most color. Then use the circular dials to rotate the shapes to replicate the look of the finished combination.
Here is the solution:
From left to right, place the colors as: Blue, Red, Green, Yellow, Purple.
Rotate each color to these positions:
Blue is touching the lower right corner.
Red is upright on the right wall.
Green is in the upper right corner.
Yellow is in the upper left corner.
Purple’s long end is against the left wall.
