TIme to update my own thread with some positive news.
I received the lock set as prescribed in Traylaw's post at top. It not only had the driver's lock assembly, but also a matching lock cylinder for the glove box plus two new matching keys for each of my fobs.
The installation of the driver's lock couldn't have been easier, as SnakeCharmer said. Excluding searching for the right torx bit in my toolbox, the swap out took me about 5 mins. To think the dealer wanted to charge me $420 labor is an outrage!
All in all it's a win, but only partially. Two issues remain.
1. The new lock did not solve my problem with my remote start system. It just doesn't work. I've checked the settings in the dahsboard, and the system is enabled. If I try to lock the door with the fob, I hear the click, but the parking lights don't flash as they should. I'm wondering if the attempted break-in damaged something else that I'm not aware of.
2. I can't figure out how to remove the old lock cylinder from the glove box. There aren't any Youtubes out there for this specific vehicle.
If anyone has any advice for these 2 issues, I'd be grateful for additional replies. Thanks.
