Thanks for your input, I only have one key. Yes, I knocked the price down for this and CA not working.. I will order another key sometime next week from Life Qulity BMW in Brooklyn. I should also have my new rheingold ISTA/INTA bundle in my shop after I get the key to play with the Beemer more and hopefully get the CA to work. Information is indeed very limited on that subject..that's why I am trying this forum... like I said, I appreciate any input!
