I don't know if you still care, but most likely the reason why the keys did not work is because they were used. I have a 2007 Toyota Avalon Limited that uses the same Smart Key system as the Lexus's do and I was also quoted a ridiculously high price for a single key. So, I ordered a key from ebay for about $60 and tried to get it programmed with no success by dealers and locksmiths. However, the locksmith just reset the system (Reset the ECU, I believe) and was able to add all of the keys needed. It was a fairly quick process about 10-15 mins. Just ask your locksmith to reset the ECU and then add the keys.
