What 4166 / 1899 Means
4166 / 1899 is a coordinate pair, not a keypad code. Read the values as roughly 41.66 / 18.99 on the in-game map grid, then travel to the spot they cross at.
The pair points away from the numbered structure. Where you read the numbers and where they send you are two different places.
Looking for a Code?
4166 / 1899 is not a password.
No keypad, safe or container takes it as digits. The numbers identify a place on the island; you read them off the clue and walk to what they name.
Where It Points
The place you read the numbers and the place they point at are separate, so open the location only when you want the destination spoiled.
Hint
The numbers belong on the map, not on the box.
Show Exact Location
The pair resolves to a remote target beside the railway, down from the chairlift line.

How Coordinates Work →Why Is the Target Somewhere Else?
Because the numbers identify a remote target for the challenge. The sign and the destination are deliberately apart, so nothing opens next to the numbers and you have to navigate to the right place.
Reached the Target?
Arriving is the location step only. The challenge still has a cooperative interaction waiting at the target.
