The door lock cylinder eventually breaks..because it is cheaply made.
The PO got a cheap, used matching door cylinder and key and installed it.
This is what I would do...
1. Any BMW key fob will unlock your door if it is programmed...easy to do .
2. So, try programming the key that starts your car to open your doors
3. If that doesn't work, get another Genuine key from an online dealer...and program it to open your door.
4. In the same programming, program the non-matching door key fob to electronically unlock the door.
5. keep the non-matching key for the door for occaisonal manual operation...like never.

I think you nailed it- as I get deeper into this project I've now realized the driver's door has been exchanged. I'm pretty sure both keys have dead batteries (they look original) so I opened up the "good" ignition key this evening carefully with a razor blade and have a new battery en route that I will solder in place and hopefully be able to program and have a single good one. If that works I will replace the battery in the "door" key and program that one as well. Ultimately I will also need to order another key from the dealer as I want to make sure to have two "good" keys that can do it all.
Really appreciate the insight and direction on this! I'll follow up once I have more info to add.
