- Hole Diameter: 1-1/2" (38mm) or 2-1/8" (54mm)

3.2 Install the Latch and Strike
Install the latch into the door edge. Ensure the latch face is flush with the edge of the door. Secure it with the provided latch screws. Install the strike plate on the door frame, aligning it with the latch bolt.
3.3 Install Exterior Assembly
Route the cable from the exterior assembly through the door hole, ensuring the latch is fully retracted. Secure the mounting plate to the door, making sure it is perpendicular to the floor and parallel to the door. Do not overtighten the screws.
3.4 Install Interior Assembly
Keep the thumb turn in the vertical position. Connect the cable from the exterior assembly to the socket on the interior assembly. Carefully tuck the cable into the designated channel. Attach the interior assembly to the mounting plate and tighten the three screws.
3.5 Door Handing
After installing the interior assembly, install four new AA alkaline batteries. Use the Reset Tool to press and hold the Reset Button for more than 5 seconds until you hear a long "BEEP". If the reset is successful, the latch bolt will extend on its own to learn the handing orientation of the door (left-handed or right-handed).
