Precautions before beginning: To ensure a successful connection,

1. Please make sure you are using the correct Smart Life app:

2. Please make sure Bluetooth is enabled on your phone; otherwise, the app interface will continuously display “Searching.” Please refer to the example below:

There are two primary methods to activate and enter the “Add Bluetooth Administrator” state.

The first involves resetting the door lock and restoring it to factory settings：

1.1. The first is to remove and reinstall the battery, then press and hold the “Deadbolt” button on the rear lock for about 5 seconds until the prompt "Enter initialization code" appears. 

Enter "000 + unlock button" on the keyboard to complete the reset process.

⚠Note: After the Deadlock function is turned on, only the Programming Code can unlock, and all user code cannot unlock (using the Programming Code to unlock the lock will remove the Deadlock restriction.)

1.2. The second is to restore factory settings.

Use a Screwdriver to remove the interior assembly. 

Press and hold the reset button for 5 seconds until the voice prompt & green light flashing, the master code will return to the manufacturer's default code “123456”.

⚠Note: After restoring the factory, change the master passcode as soon as possible! Because the master password can unlock the door.

The second method is through programming:
2.1. Unlock button + 3 + Unlock button + PC + Unlock button + 4
A voice prompt will then sound: Please add a Bluetooth administrator.

2.2. Initialization setting: Unlock button + 4 + Unlock button + PC + Unlock button → 2 (Confirm reset). Pressing any button will trigger the voice prompt: Please add a Bluetooth administrator.
