Most of the door key systems use Bluetooth not NFC. Mainly because Apple didn't used to allow apps to use the NFC chip as they wanted to ensure Apple pay seemed trusted and secure.Hilton have also trialed NFC door locks, using the app. I haven’t ever got it to work and they seem to have mostly abandoned it too.
The Hilton one we used several years ago was definitly Bluetooth or similar as you didn't need to get close enough to touch the door.
