Step-by-Step Installation
- Install the Latch and Strike:
a. Insert the latch into the door edge. If the backset is 2-3/8" (60mm), proceed directly. If 2-3/4" (70mm), extend the length of the latch by adjusting the silver or black paddle as shown in the video (0:31-0:43).
b. Secure the latch with screws.
c. Install the strike plate on the door frame, aligning it with the latch, and secure with screws. - Install the Keypad Digital Deadbolt:
a. Keep the torque blade horizontally. Align it with the hole on the latch and go through (video 0:50-0:54).
b. Route the cable below the latch (video 0:55-0:57).
c. If the hole diameter is 1-1/2" (38mm), remove the spacer from the exterior assembly (video 0:58-1:03).
d. Install the mounting plate, ensuring it is horizontal and vertical, and secure with screws (video 1:05-1:10).
e. Determine if your door is right-handed or left-handed. This is crucial for correct thumb turn direction (video 1:11-1:21).

f. Confirm the thumb direction: Move the slide switch to 'R' for right-handed doors (vertical thumb turn) or 'L' for left-handed doors (horizontal thumb turn) (video 1:22-1:38).
g. Insert the cable connector to the socket on the interior assembly. Push it in firmly until it's fully attached. Ensure the power cord is properly plugged in (video 1:40-1:45).
h. Align the axle with the hole in the latch (video 1:47-1:50).
i. Install the interior assembly screws (video 1:51-1:53).
j. Insert 4 AA Alkaline batteries and put on the battery cover (video 1:54-2:00). - Install the Front and Rear Knob:
a. The base of the spindle must be rotated, aligning to the hole horizontally (video 2:33-2:36).
b. Secure the knob with screws.

- Keypad Care: Keep the keypad free from dirt and debris. If the keypad becomes unresponsive, try cleaning it gently.
Troubleshooting

- Incorrect door handing: If the lock mechanism is not operating correctly after installation, re-check the door handing setting (R/L switch) on the interior assembly and adjust if needed.
- App connectivity issues: Ensure Bluetooth is enabled on your phone and the lock is within range. Try restarting the app or your phone.
- Forgotten master code: If you forget your master code, you can reset it via the DDLock App under Settings > Basics > Admin password.
User Tips
- Regular Battery Checks: Although the lock alerts you to low battery, it's good practice to check battery levels periodically, especially before extended absences.
- Secure Code Management: Change the default master code immediately after installation. Avoid using easily guessable codes.
- Physical Key Backup: Always keep a physical backup key in a secure, accessible location outside your home in case of electronic failure or dead batteries.
- Door Alignment: Ensure your door is properly aligned and closes smoothly. Misaligned doors can cause the deadbolt to jam or prevent proper locking.
