5. Setup and Installation
This section outlines the general steps for installing the deadbolt. Specific details may vary based on your door type and existing bore holes. Professional installation is recommended if you are unsure.
5.1. Prepare the Door
Ensure the door has standard bore holes for a deadbolt (typically 2-1/8 inches for the main bore and 1 inch for the latch bore). The backset (distance from the door edge to the center of the main bore) should be compatible with the deadbolt's adjustable latch.

5.2. Install the Latch Bolt
Insert the latch bolt into the 1-inch bore hole on the edge of the door. Ensure the latch faceplate is flush with the door edge and secure it with the provided screws.

5.3. Install the Deadbolt Cylinders
Align the exterior and interior cylinders with the main bore hole, ensuring the spindle passes through the latch mechanism. Secure the cylinders together using the through-bolts provided, tightening them evenly.

5.4. Install the Strike Plate
Mark the position of the latch bolt on the door frame when the door is closed. Chisel out a recess for the strike plate and secure it with screws. Ensure the latch bolt extends smoothly into the strike plate opening.
5.5. Test Operation
With the door open, insert a key into both cylinders and turn to extend and retract the deadbolt. Close the door and test again to ensure smooth operation and proper engagement with the strike plate.
6. Operating Instructions
The Lockwood 005 Paradigm Deadbolt offers multiple operating modes:
- Secure Mode: To lock or unlock the deadbolt from either the inside or outside, insert the key into the cylinder and turn. The LockAlert indicator will show the locked/unlocked status.
- Safety Mode: This mode allows the deadbolt to be locked from the outside using a key, while still permitting free exit from the inside without a key. This is typically achieved by a specific key turn or internal mechanism. Refer to the specific keying instructions provided with your lock for details.
- Passage Mode: In this mode, the deadbolt remains retracted, allowing free entry and exit without the need for a key. This is useful for periods when the door does not need to be secured. This mode is engaged by a specific key turn or internal mechanism.
The LockAlert status indicator provides a quick visual reference for the lock's current state (locked or unlocked).
7. Maintenance
Regular maintenance ensures the longevity and smooth operation of your deadbolt:
- Cleaning: Wipe the exterior surfaces with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the finish.
- Lubrication: Periodically apply a small amount of graphite-based lubricant or a silicone-based spray into the keyway and on the latch bolt mechanism. Do not use oil-based lubricants as they can attract dust and grime.
- Inspection: Annually check all mounting screws for tightness. Ensure the deadbolt extends and retracts smoothly without binding.
8. Troubleshooting
