I realize this doesn't directly answer your question, but it suggests that replacing and/or reprogramming the BCM might be necessary.
Thanks for your reply. I don’t think that may be the issue, because this is most likely caused by the battery being dead for so long... but I’ll keep that in mind. I’m going to see if it will recognize the spare key, once I find it.
