Our Corvette had a 'slug' of those programmable options/features - Key #1 vs. Key #2, but once set, I never really messed around with them, except when I had to reprogram a key fob. There is still quite a bit of programmable features in the '06 H2, and upon vehicle delivery yesterday, the salesman helped my wife set-up the #1 driver memory position to her own personal settings; i.e., reverse mirror tilt option, seating position, sideview mirror position, etc.; however, these settings are not key specific. I actually prefer it this way, especially after borrowing my wife's Corvette key when I was too lazy to retrieve my own. Because of our substantial height difference, as soon as my knees were forced up and into my chin with the steering wheel into my gut, I quickly learned that it was much safer to utilize my own Corvette key.
