i have the same problem, except a shop that was working on my car lost the wheel lock key. I went to a honda dealer and they have a master set of the keys. they test each one on your wheel lock and whichever one matches, you'd have to order from McGard yourself. Unless you can order it from your Honda dealer.

Make sure it's a honda wheel lock though. if not, try to find out where the previous owner bought it from and contact the company.
