Hi, found this interesting ebay listing. looks like they can make a key for a Crossfire if you send in your skreem unit. Price is $170 plus $10 shipping. After you get the key from them you could probably take the transponder chip out and put it in a remote fob if you wanted. This also tells me there must be some way yo read the skreem code and program it to the chip. On there website, looks like you can get two keys for $199 plus shipping. Keep in mind you'll still have to cut the key blanks.
