Access does not prove starting authorization
For your model
The 2019 LaCrosse manual separates the removable lock key from its keyless ignition system. Its immobilizer looks for a valid transmitter when the ignition button is pressed.
Before arranging the work
A door-opening blade should not be described as a complete spare if the car will not start with it. For a replacement enquiry, include the year and whether any working transmitter remains.

Key questions
Can a cut LaCrosse door key replace a missing smart remote?
For the keyless-ignition example in the 2019 manual, the metal key serves the locks and the valid transmitter serves starting authorization. A complete replacement request needs both functions checked for the actual car.
