Ah, I forgot about that. I had to take the key out of the NAS too, to a different device. That made no sense at all. And almost all of the implementations of the key server you need cost thousands of dollars in licenses.
Edit: what they deploy on their NAS is an old version of a testing implementation of the KMIP protocol. PyKMIP: https://github.com/OpenKMIP/PyKMIP
