I have had the same issue with my 2024 Sportage HEV when the car was 3 months old. Had left it in the garage with the doors locked while away for 2 weeks. Came home to find I could not unlock the doors. Popped the keyhole cover off the driver's door & used the 12V reset button to get power back. Researching online, it appears that the battery will drain faster if the doors are left unlocked, but at least then I will not have to use the key to get in. Of course, this precludes my taking the car to the airport. Good thing the 10 year old Honda CRV does not have this issue.
