do you know where one might find the instructions to program these?
Looks like you've already got the info you need, but as an FYI, I bought the key that PLROD mentioned (that siremotes is selling on eBay) this week, and the seller sent me detailed instructions via email. I followed the instructions today and was able to program the new key without any problems. But, you can only reprogram the new key if you have a master key that's already programmed.
