I've been making a plugin (an advanced version of sm_addadmin) to parse through admins.cfg and admin_groups.cfg by using Keyvalues (since they are in that format).

I am having trouble actually changing values in the admins.cfg file though (such as the auth key). It says it manages to delete the key then I force it to be created.

I don't know how to actually save the new keyvalues to an existing file as I have only ever used keyvalues to get information, never write it.

Look at KeyValuesToFile. It will dump the kv structure to file.

Note that it doesn't preserve formatting, so everything will be written on one line, I think. Comments will be lost.

Brilliant!

Had a few issues with it but worked them out now and everything works just like it should now (no silent errors).

For others, you need to go back to the main Key value using KvGoBack to dump all the keyvalues.

you would need to create a txt saving system and you would have to save and load SteamId and Admin_Flag's cheak out
