What if the hotel door lock won't open?

First of all, we must find the problem. Change a card first, and then go to the sensor to see if the card is broken; Second, make a time card in the door lock management, without changing any parameters, make the card directly (computer time is the same as Beijing time), then take the card as the address card of the room, then go to the room, first use the time card to induce, then induce the address card, and finally make the room card, which should be enough.
