If you need to use more than one cell phone to connect to pair the door lock for operation, please note that a lock cannot connect to two APPs at the same time due to connecting the APP via Bluetooth, so you need to disconnect the other Bluetooth connection before you are able to use another cell phone to pair and operate the APP to open and close the lock.

 

If you need more detailed information, please contact our after-sales customer service for a detailed video tutorial.
