Thank you for your response Mulchman.
The metal key and key fob were shipped to dealership in 2 different manila envelopes. Dealership sells them separately ($50 for the metal key and $200 for the key fob, though other local BMW dealership wanted to charge more). Metal key works as I tested it in glove compartment. When I follow the step #8 in your guide my existing (working) key reported as #3. The new key is #256. I thought it should be assigned to number 1-10. All 10 keys were enabled. I will try to do what you suggested when my wife comes home from the store.
When you received your CA key fob (not mechanical key) were you able to open the door?
