Ok, I solved it, the keys can't be updated with write plain maced, they need to be written encrypted.

I have another problem though, I can only use first authentication, afterwards I can't complete the challenge for the following authentication command. I'm probably missing a step or two. At the moment I'm working around it with resetting auth, but I'm not sure this is the correct way. How can I correctly use the challenge from following authentication, 0x76?
