This is coming in a bit late, but I bought an STI blank off eBay which I hope to get cut by a locksmith to match existing, as well as the remote separately, also from eBay which I can apparently recode myself using some kinda crazy recode sequence involving turning ignition on 10 times in 45 secs etc etc. If interested, will let you know how I go. All up has cost me $90 so far.

nice, let us know how you go man
