I really didn't want to deal with the dealership after multiple bad experiences... but I was able to find
TWO different options for obtaining the factory code... and I verified that
BOTH of these methods work on Lightning.
OPTION 1- Using both keys and inserting under the rubber flap of the cupholder as shown here:
OPTION 2- If you don't have both keys, this method also works but requires removing a few trim panels. Unfortunately, I already used this method before I found the super easy method in Option 1. The BCM is pretty hard to read, but with some careful maneuvering of a flashlight and zoomed in phone camera, you can complete this in 5-10 minutes.
