2.1 Unpacking and Component Check
- Carefully remove all items from the packaging.
- Verify that all parts listed in the packing list are included.
- Inspect components for any signs of damage. Do not proceed with installation if parts are damaged.
2.2 Door Preparation
- Determine the desired height for the lock on the door.
- Affix the provided drilling template to the door, ensuring it is level and correctly positioned.
- Drill holes according to the template for the spindle, fixing bolts, and latch mechanism.
- Prepare the door edge for the latch plate mortise.
2.3 Lock Assembly and Mounting
- Insert the latch into the prepared mortise in the door edge and secure it with screws.

3. Operating Instructions
The Lockwood Mechanical Digital Lock SC operates using a numerical code. The code is non-sequential, meaning the order of pressing the digits does not matter, only that all correct digits are pressed. The code must always be prefixed by the 'C' button.
3.1 Opening the Lock from Outside
- Press the 'C' button to clear any previous entries.
- Enter your 4 to 6 digit code by pressing the correct numerical buttons. The order of the digits does not matter.
- Once all correct code digits are pressed, turn the thumbturn to retract the latch and open the door.
- Release the thumbturn to allow the latch to extend and secure the door.
3.2 Opening the Lock from Inside
From the inside, the lock provides a free-exit mechanism.
- Simply turn the interior thumbturn to retract the latch and open the door.
- Release the thumbturn to allow the latch to extend and secure the door.
3.3 Changing the Code
Refer to the specific instructions provided with your lock for changing the code. This typically involves removing the lock from the door and adjusting internal tumblers or pins according to the desired new code. It is recommended to perform this operation carefully and test the new code thoroughly before re-installing the lock.
4. Maintenance
Regular maintenance ensures the longevity and optimal performance of your Lockwood Mechanical Digital Lock SC.
4.1 Cleaning
- Wipe the exterior surfaces with a soft, damp cloth.
- Avoid using abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish and internal components.
- For satin chrome finishes, a mild, non-abrasive polish can be used sparingly to maintain luster.
4.2 Lubrication
- Periodically apply a small amount of silicone-based lubricant to the latch bolt and internal moving parts (if accessible without disassembly).
- Do not use oil-based lubricants, as they can attract dust and debris, leading to sluggish operation.
4.3 General Check
- Check all screws and fixings periodically to ensure they are tight.
- Ensure the door and frame are not warped or misaligned, as this can put undue stress on the lock mechanism.
