I’m checking in with someone at Ford but haven’t heard back.
So far, it seems the only option is to switch to the correct vehicle in the Ford Pass app. FP only seems to be able to simulate one fob at a time.
I also encourage you to switch a minute before you reach the vehicle. I suspect the PaaK feature in FP has to communicate with the mothership to download the current series of security keys. If you switch just in time to open the door, you may not have the security key in time to start the vehicle.
