Hotel card lock, the total card can open the door, room card can not open any questions?
Obviously the problem ah, the room card is broken
The time to maintain the door lock first
There are many reasons, but the total card is only identify the data format. So it can be opened. There can be room number wrong. Can (empty the room number again) 2. It is possible that the card has expired. Reissue card. I do not know the door lock that you use, and some locks are very troublesome. I am now in a smart door lock structure design. Understand some of this, do not understand can ask me.
