How do I setup a DKIM record for another site
How do I setup a DKIM record for the subsite in this example:
My DKIM for the mainsiteurl.com is working fine but I need to make it so the subsite can send email successfully.
Thanks

Just set it up like DKIM was setup for the main site.
You can use the same key or different keys....
Best to have a key/selector pair PER server. If a server (key) is compromised you have minimal damage to recover. Just revoke the DNS records.

Thanks that worked
Please can you share more details about the system(s) that you're running behind domains? DKIM obviously requires not just the DNS records, but that the system(s) authorised to send mail using the subdomain generate the keys and use them for signing outbound mail.
Whatever system you have should provide a mechanism for creating a DKIM record. It will advise you what DNS TXT records need to be created, at what hostnames, to properly register them in the DNS.
