Not sure what exactly have done so far, perhaps somehow the system is slightly confused... Anyhow try this and see if solves the issue, assuming your HL all doors are currently locked, grab and hold of the driver-side exterior handle while use the physical key to unlock the door, open the door wait for 10-seconds then close the door, now lock the door using your key fob. Do this with only one fob.
If the above returns the system to normal, use the 2nd key fob to lock/unlock normally...
P.S. Not sure about using the app... Force stop the app/disabled until you have the system working normally with the 2 key fobs.
