Step 1
Measure to confirm that the door is between 13/8” ∼13/4” (35 mm-45 mm) thick.
Note: For thicker doors between 1^{3} / 4'' (45mm) - 2^{1} / 4'' (57mm), thick door kit is requested. Please visit www.ultraloq.com to order the "ULTRALOQ Thick Door Kit".

Step 4
Measure to confirm that the diameter of the hole in the door edge is 1^{\prime \prime} (25 mm).
Step 5
Measure to confirm the depth of the hole in the frame is at least 1''(25mm)


If you have a new door, please drill the holes according to Drill Template.
Step 1: Install the Bolt
- Insert the bolt into the door. Making sure the "UP ↑"icon faces upward.
Note: By default, the bolt is set to a 2-3/8" (60mm) backset.
- To adjust to 2-3/4" (70mm): Make sure the bolt is fully retracted. - Press the bolt, then twist it until you feel a slight click. This locks it in the extended backdrop position.
Note: Always ensure the bolt is retracted before making adjustments.
Step 2: Install the Strike
- Align the strike plate with the door frame. - Secure it in place using the provided screws A(x4)

Step 1: Position and Install
- Ensure the bolt is fully retracted. - Make sure the cylinder tailpiece is horizontal, with the bump pointing upward. - Carefully install the Exterior Assembly onto the door.
Do not insert the mechanical key during installation.
Step 2: Route the Cable
- Carefully thread the cable through the hole located below the bolt to the interior side of the door.


If your door has a 1 1/2”(38 mm) bore hole, remove the spacer from the exterior assembly as shown.

With No Spacer


Step 1: Route the cable
Route the cable through the hole in the Interior Assembly Mounting Plate.
Step 2: Secure the Mounting Plate
Secure the Interior Assembly Mounting Plate to the Exterior Assembly using Screw B(x2).

5. Installing the Interior Assembly
Warning: Do not install the batteries before installing the interior assembly, as this may prevent the keypad from powering on properly.
Step 1: Remove Battery Cover
Remove the battery cover from the Interior Assembly.
Step 2: Connect the cable to the Interior Assembly

Step 3: Set to Unlocked Position
- Rotate the knob to the vertical position to keep the lock unlocked during installation.

Step 4: Attach and Secure

6. Installing the Batteries and Performing the Door Handling Process
This step helps your lock learn which way your door opens, so it can work properly.
Step 1: Set to locked position
Rotate the knob to the horizontal position to keep it locked.

Step 2: Insert Batteries
- Insert 4 AA alkaline batteries into the battery compartment. - Reattach the battery cover.



Note: Any fingerprint or pressing any 4-8 digit code then ULTRALOQ Button can unlock U-Bolt Pro Wi-Fi in Factory Default Mode.
7. Installing the Door Sensor(Optional)
Door sensor lets you know whether the door is open or closed through the App. When Auto-Lock is enabled, your LOCK will automatically lock only when the door is fully closed.
Guidelines:
- Do not mount the door sensor on the keypad side of the lock. - Avoid installing the sensor on metal doors that interfere with the internal magnet. (In such cases, the door sensor may stick to the metal door magnetically and malfunction.)
- The sensor is suitable for:
1. Wooden doors. 2. Metal doors that do not interfere with the sensor's
magnetic field (i.e., the sensor does not stick magnetically to the door).
Installing with Screw D
- Drill two holes at the marked positions. - Press the door sensor against the wall and secure it using Screws D (x2). - Attach the door sensor cover by sliding it from top to bottom along the chute until it clicks into place.




Note: Door sensor should be mounted as close to the edge of your door frame as possible, or within 0 to 1"(25mm) from the edge, and as close to the bottom of the extended deadbolt as possible, or within 0 to 1"(25mm) from the edge.
