Yes you can get a blank key cut at a good locksmith, No you can't get the key recoded. As has been posted on here-many times-every key has an unique fingerprint called the lockset code which is programmed into the BECM. When you press the fob button the code is sent to the BECM for a match-no match,no start,no remote unlock. Your expert may be good, but I doubt he's not that good. New keys are cut in the U.K, then sent to Germany to have the unique code programmed relative to your VIN. Time and time again these Ebay sellers list them and get mugs to buy them sometimes for around £50. Only sure way to get it to work is to buy the keys,BECM, door and ignition locks as a set.
