The door lock of the rental house is swiped and beeped.

The reason why the door keeps ringing is that the access card beeps after swiping the card, and the reason why the door cannot be opened is: the problem caused by degaussing the access card used.

The solution is: if the access card is degaussed, you need to go to the property to replace the access card in time, which can solve the problem that the door cannot be opened due to degaussing the access card. The lock of the credit card is dripping, so I can't open the door. Generally, it is an alarm sound caused by insufficient battery voltage or chip failure. The electronic door lock for swiping the card needs to be powered by the battery to drive the mechanical lock core to close and open the door lock. If the battery voltage drops after long-term use and cannot drive the mechanical lock core, the voltage detection circuit system of the chip will automatically give out a continuous alarm sound. In this case, you need to replace the new battery before you can resume normal use.
