Details of the problem:
The master card is gone, but there is a remote control, but I don’t know the password! If you want to retrieve your password, you can use a master card if you can.
Expert answer:
Hello! Thanks for using our company's products! Open the device to find the RESET button, and then short-circuit RESET. Wait for 2 seconds to hear the prompt tone (di) and then release, the access control will restore the management password to the factory default value (1234).
If you continue to hold down RESET for 5 seconds, and then disconnect the RESET button after hearing a continuous beep (di...di...di), the access control is being initialized automatically, and the device initialization is complete after the beep ends.
All card data, management password, etc. are all cleared and restored to the factory default values (recovery management password: 1234). Then you can use the remote control to remake the master card.
