A peer of mine - a hacker - figured out a way to put a keylogger on my computer that I can't get off with Norton Antivirus - I use Mac OSX - how can I get this off my computer?

You got a lot of idiot windows answers. The truth is , this keylogger is not viral, like the Windows viruses. You were affected by a peer.

He has the key %26 program to get it off!

You can search for the program, but most claim they can't be detected. Unfortunately, if you can't find the program, you need to cleanly re-install os x(not re-format or just update).
