Thanks a million for the graphic depiction. I've been hunting for that darn thing for almost a year now. I found it within 5 minutes after seeing your post. Big kudos to you for taking the time to rip your X apart and take pictures for us keycode challenged individuals!
Thanks to mattsexcursion & vettdvr for the rapid response on the door code macro. I received emails from both, and I really appreciate it. I'll start the process this weekend, and hope I'll be as lucky as those who've already done it and found their code relatively quickly.
