- Insert the spindle through the latch mechanism.
- Position the exterior keypad assembly and interior lever handle assembly onto the door, aligning them with the spindle and through-bolt holes.
- Secure both assemblies together using the provided mounting screws. Do not overtighten.

5. Operating Instructions
5.1 Opening the Door from the Outside
- Enter your pre-set code by pressing the correct sequence of buttons on the keypad.
- Once the correct code is entered, turn the exterior lever handle downwards. This will retract the latchbolt.
- Push or pull the door open.
Note: The CL410-SS features a "C" button (Clear) which should be pressed before entering a code to clear any previous incorrect entries.
5.2 Opening the Door from the Inside
From the inside, simply turn the interior lever handle downwards to retract the latchbolt and open the door. No code is required for exit.
5.3 Locking the Door
The Codelocks CL410-SS automatically locks when the door is closed. The spring-loaded latchbolt extends into the strike plate, securing the door without any manual action required after closing.
5.4 Changing the Code
The code change procedure for mechanical locks like the CL410-SS typically involves removing the lock from the door or at least the back plate of the exterior assembly. Inside, there are usually a series of numbered pins or tumblers that can be moved to different positions (e.g., 'in' or 'out') to set the code. Refer to the detailed code change instructions provided in the full product manual or on the Codelocks website for your specific model. It is crucial to follow these instructions precisely to avoid damaging the mechanism or rendering the lock inoperable.
6. Maintenance
Regular maintenance will ensure the longevity and smooth operation of your Codelocks CL410-SS.
- Cleaning: Wipe the lock's exterior surfaces with a soft, damp cloth. Avoid abrasive cleaners, solvents, or harsh chemicals, as these can damage the stainless steel finish and internal components.
- Lubrication: Periodically apply a small amount of silicone-based lubricant (do not use oil-based lubricants) to the latchbolt and spindle mechanism to ensure smooth operation. Do not lubricate the keypad buttons.
- Inspection: Regularly check all screws and fixings to ensure they are tight. Inspect the latchbolt and strike plate for any signs of wear or misalignment.
- Environmental Factors: While designed for exterior use, extreme weather conditions may affect performance over time. Ensure proper drainage around the door if exposed to heavy rain.
