The numbers 4166 and 1899 represent coordinates 41.66 and 18.99, not a four-digit lock code. Use the map grid or a GPS to reach the hidden button, then split the team between the button and the original glass container.

Reliable walkthrough material recommends solving five puzzles and progressing the Red Tower for the map, or finding a GPS near the Green Tower.
Reach 41.66, 18.99
Use the map grid to narrow the location or watch live GPS values while moving. Keep one fixed orientation when giving directions.
Finish with two roles
One player remains at the hidden button while another returns to the glass container for the reward. The puzzle still requires cooperation.
