This is an incredible find, Pawpac! There were a good number of cars sold that only came with one key. That was very curious, since most came with two. Up until now I've never heard of anything that even came close to providing a reason. Perhaps you've stumbled on it. If anyone else out there has one of these one-key smarts, you might try that same technique. Perhaps there was a portion of the original smarts that all had these second keys "hidden" for some strange security reason on the trip over. What an unusual and valuable piece of information. Thanks so much, Pawpac, even if it's just an odd coincidence.
