Where is the key to open Dal Valstegg?

I read somewhere that it's not really a key but three coins and put them in a lockbox...tried that didn't notice anything different.

Have you

found the three Dal'Valstaag Coins and put them into the box near the treasury? The door next to the box should be openable.

Thanks. Not sure what box you mean though.

this box. Like I said, the door nearby should be openable (even if the lock displays that it needs a key).
