I dropped my access card. I have the password. I don't know how to lose it. Ask for advice.

Hello, this kind belongs to double electronic door.

There are two ways to unlock the lock:

Access control electronic card (as big as a bank card, you can generally reissue it at the property management office, depending on the owner's relevant documents and the meaning of the property management office)

Password unlock.

Method: Touch the electronic card at the top of the screen, and you can directly push the door (pull) when you hear the ticking sound!

The way to unlock the password is to enter the password, and then press the "Open" button in the lower right corner to open the electronic doors of individual manufacturers, or press it before entering the password, and then enter the password. The ways and means are similar, I hope I can help you and wish you a happy family!
