4.1. Step 1: Prepare the Door & Check Dimensions
Measure your door's dimensions to ensure compatibility and proper installation.

- Hole Diameter: The hole in the door should be 1-1/2" or 2-1/8" (38mm or 54mm).
- Door Edge Hole: The hole in the door edge should be 1" (25mm).
- Door Thickness: The door thickness should be 1-3/8" to 2" (35mm to 50mm).
- Backset: The backset is either 2-3/8" or 2-3/4" (60mm or 70mm).
- Minimum Distance: Ensure a minimum of 4" (101.6mm) between the two main holes.
- Door Frame: Make sure the door frame is aligned with the door and there are no obstructions. The hole in the door frame should be drilled a minimum of 1" (25mm) deep.
Optional: Instructions for doors with 1-1/2" (38mm) holes
If the latch bolt is stuck when temporarily installed, you may need to extend the latch hole. Use a 1" (25.4mm) drill bit to extend the latch hole at least 13/64" (5mm) deep. If the latch bolt is still stuck, remove it and chisel out a small channel at the top of the hole to allow the cam to rotate.
4.2. Step 2: Install the Latch & Strike
- Confirm Backset and Adjust Latch: Hold the latch in front of the door hole, flush against the door edge. Check if the slot hole is centered. If the backset is 2-3/4" (70mm), rotate and pull the latch to extend its length.
- Install the Latch: Insert the latch into the door edge. Secure it with the provided latch screws.
- Test Latch Bolt: Use a screwdriver to test if the latch bolt extends and retracts properly. Ensure it retracts completely in the unlocked position.
- Install the Strike: Install the strike plate on the door frame using the strike screws.
4.3. Step 3: Install Exterior Assembly
- Measure Hole Diameter: If the hole diameter is 1-1/2" (38mm), remove the spacer on the exterior assembly. For 2-1/8" (54mm), proceed directly.
- Route Cable and Insert Torque Blade: Route the cable below the latch and insert the torque blade through the slot in the latch. Do not insert the mechanical key into the cylinder during this step.
- Install Mounting Plate: Install the mounting plate with the mounting plate screws. Do not overtighten. Both exterior and interior assemblies should be parallel to the door edge.
4.4. Step 4: Install Interior Assembly
- Disassemble Battery Cover: Remove the battery cover from the interior assembly.
- Check Door Handing: Determine if your door is left-handed or right-handed from an outdoor perspective (hinges on left = left-handed, hinges on right = right-handed). Adjust the slide switch on the interior assembly accordingly:
- Left-Handed Door: Move the slide switch to "L" and turn the thumb turn to the horizontal position.
- Right-Handed Door: Move the slide switch to "R" and turn the thumb turn to the vertical position.
- Insert Cable Connector: Insert the cable connector firmly into the socket on the interior assembly. Ensure the power cord is properly plugged in.
- Align Axle and Attach Interior Assembly: Align the axle with the hole in the latch. Attach the interior assembly to the mounting plate and tighten the 3 interior assembly screws.
- Insert Batteries: Insert new 4 AA Alkaline batteries and replace the battery cover. (Note: The life of the battery is affected by usage, usually about half a year.)

7. Troubleshooting
- Why the lock won't accept any inputs after I entered a passcode incorrectly for so many times?
The lock will shut down for 2 minutes after 5 unsuccessful attempts at entering an invalid passcode. You can unlock the lock once in the DDLock App or wait 2 minutes to continue. - What should I do when batteries are completely dead before I replace new batteries?
When the batteries are completely dead, the Mechanical Key is available to unlock. - Why the lockset locks when I unlock and unlocks when I lock?
The door opening direction might be set wrong. You can disassemble the lock and redo the left/right door setup steps. Alternatively, you can go to the DDLock App to reset the door opening direction (DDLock App - Settings - Door opening direction). - Why the latch bolt won't be extended out completely after installation?
Please review if the exterior assembly is aligned with the door parallelly. The exterior assembly should not be at a crooked angle.
