Hotel door lock system

One possibility is that one of your management cards may have a normally open function, that is, as long as this card is swiped once, the door will always open, and you can open the door without swiping it. When a new valid card swipes the card to open the door, the door returns to normal state. In which room to swipe which card next time, the door lock of which room will be opened normally. How to determine whether this is the case? It's simple. You swipe a guest card in this room, and then swipe this room. If it returns to normal, it proves that one management card has been set normally. Find this management card, cancel it and make a new one. If the room is brushed with a new card, the door lock is still in a normally open state, indicating that the door lock has been restored to the factory settings. Please reauthorize these locks and reset them. Don't worry when you encounter problems, try to rule out all possibilities. The big deal is to change the circuit board, and there is no problem that cannot be solved.
