I'm not going to be much help as I can't remember the torx size but the manual might have it. You will need the correct size as honda also puts hd locktite on the bolts. I've done three times but always with the top bridge in a vice and it was still a bitch to break them.
I'd think I'd suck it up, pay the $200, and make sure I get 3 keys. One of which, I'd hide somewhere on the bike. I won't tell you where mine is but it does require tools to get too.
