Step 1: Unbox and prepare components:

Before installation, open the package and identify all components. Lay them out for easy access.

Hardware components:

1x BLACK X deadbolt

2x Mechanical Access Keys

Box 1:

1X Strike box

1X CR2 3V Battery

Box 2:

1x Allen key

1x Strike plate

4x M4 x 0.71" (18mm) Screws

Step 2: loosen the screws

1. Insert the supplied Allen key into the screw socket.
2. Turn the Allen key counter-clockwise to loosen the screw.
3. Repeat the same process for the screw on the opposite side of the lock.

Step 3:  disassemble the BLACK X mechanism

1. Rotate the BLACK X mechanism counter-clockwise to loosen the body. Note: Refer to the arrows in the diagram for guidance.
2. Carefully separate the lock body and ratchet housing as shown in the diagram.

‍

Step 4: Remove the Fasteners

1. Insert a screwdriver into the designated fastener slots, as illustrated.
2. Turn the screwdriver counter-clockwise to loosen and remove the fasteners.
3. Once the fasteners are removed, gently detach the components, following the directions shown in the diagram, to fully separate the lock for assembly preparation.

Step 5: Extracting the existing Cylinder:

1. Use a screwdriver to remove the screws securing the existing Lock.
2. Carefully pull the cylinder straight out of the lock housing.

Step 6: Check Latch Orientation

Before installing the cylinder, check that the latch orientation is correct.

Ensure the top mark on the latch housing is facing upward, as shown in the illustration.

Check the latch position:

• The slanted side of the latch must face the door frame (strike plate).

• The flat side must face the interior side of the door.

This orientation allows the latch to retract smoothly when the door closes.

If the latch is correctly positioned, continue to Step 7.

If the latch is facing the wrong direction, follow the instructions below to reverse it.

Reversing the Latch Direction

1. Locate the release tab on the slanted side of the latch.

2. Lift the release tab to unlock the latch mechanism.

3. Using the Allen key, loosen the Hex socket screw.

4. Remove the latch from the housing.

5. Rotate the latch 180° to the correct orientation.

6. Insert the latch back into the lock housing.

7.  Tighten the screw to secure the latch.

8. Push the locking slider (black piece) toward the latch until it is fully inserted.

9. Push the release tab down to secure the latch mechanism.

‍

⚠ Important

• Ensure the locking slider is fully inserted.

• If the locking slider is not fully pushed in,

the release tab cannot lock correctly.

Do not lock the release tab until the locking

slider has been fully inserted.

Step 7: Latch Function Check

Before inserting the cylinder, confirm the latch operates correctly.

Press the latch and ensure that it retracts fully into the housing.

Release the latch and ensure it returns smoothly to its original position.

1. If the latch operates correctly, continue with the cylinder installation.
2. If the latch does not retract fully or does not return properly, repeat Step 7 and ensure the latch, release tab, and locking slider are positioned correctly.

Step 8: Install the Cylinder

1. Slide the cylinder straight into the lock housing on the door, as shown in the diagram. Ensure the cylinder is fully aligned with the screw holes.

Note: Insert the cylinder in the orientation shown in the diagram, with the latch facing upward.

2. Secure the cylinder by tightening the 2 supplied screws.

3. Insert the strike box into the door frame, then secure the strike plate using the supplied screws.

Step 9: Installing the CR2 battery

1. Use a flathead screwdriver to open the dual-function battery compartment cover. Turn the screw half a turn and press down on the latch to release the compartment.

2. Insert the battery release tab into the lock. Place the CR2 battery into the BLACK X device, ensuring the positive (+) and negative (-) ends align with the symbols on the battery pull tab. A beep will confirm the device is operational.

3. Return the battery compartment cover to its original position with the tab facing outward from the lock. Use the flathead screwdriver to turn the screw back to its locked position.
