- Install the Deadbolt: Ensure the deadbolt is adjusted to the correct backset (2-3/8" or 2-3/4"). The word "UP" on the deadbolt should face upwards, and the bolt should be in the retracted (unlocked) position. Insert the deadbolt into the door edge and secure it with two screws.
- Install the Exterior Assembly: Place the spindle vertically before inserting it into the deadbolt. Pass the cable through the right bottom hole of the mounting plate, ensuring the side with "Cable Hole" faces outside. Keep the spindle vertical and pass the cable under the deadbolt.
- Secure the Mounting Plate: Screw the mounting plate firmly to the door, ensuring it is flush and stable.
- Install the Interior Assembly: Keep the knob on the interior assembly vertical. Plug the cable from the exterior assembly into the designated port on the interior assembly. Carefully align the interior assembly with the mounting plate and spindle, then tighten the screws into the interior assembly to secure it.
- Insert Batteries: Open the battery cover on the interior assembly and insert four (4) AA batteries (not included), ensuring correct polarity. Close the battery cover.
5. Initial Setup and App Pairing
To fully utilize the smart features of your SMONET lock, you need to pair it with the "Smart Life" app and connect the G3 WiFi Gateway.
