4 AA Alkaline Batteries (not included)

Step-by-Step Installation:

Prepare the Door: Ensure your door meets the specifications outlined in the "Specifications" section.
Install the Latch Bolt:

- Adjust the latch bolt length to 2-3/8" (60mm) or 2-3/4" (70mm) backset as needed.
- Ensure the spindle hole is at the center of the door bore hole.
- Make sure the axle hole is at the end and flush with the ground, not in the middle and tilted.
- Position the beveled edge of the lock tongue to face the direction in which the door swings shut.
- Insert the latch bolt into the door edge and secure it with screws.
Install the Front Panel (Exterior Keypad):

- Adjust the door handle direction on the interior assembly by rotating it to the left or right.
- Insert and tighten the screw to secure the back handle. Make sure the screw is tightened firmly and in place. Otherwise, the handle might be non-rotating.
