in hotels, if you lose your room key card, how are they able to reprogram the new one so it works and the old one doesn’t?

Question

Is there some system that transmits information to your door card reader on what the new key is, or is it something different entirely?

Answer 1

It depends on the type of lock, for systems I manage the strikes (the device that locks the doors, often with a magnet or something) are connected to a controller board. So the invalidated card can be immediately taken off the list of allowed key cards. If the controller card is disconnected, you have to go to the strike and manually program it.
