I found this site while poking around ebay. They sell a 6 piece set of secure Torx keys that includes the T-8 needed for the I-opener. The set goes for $7.95 plus s/h ($2.99 uninsured, 3.99 insured, 5.99 UPS ground) Here's the description from their page:
6pc Precision Tamper Resistant Star Key Set. Includes T-4, T-5, T-6, T-7, T-8, and T-9. These are about 2.75" in length.
These should do the trick, I'll confirm it for sure when they arrive. I posted this because I've heard on this board that some people have payed up to $20 for a similar, though somewhat larger, set. Anyhow, I'll probably have them by next weekend. check back then.
