Step-by-Step Installation:
- Prepare the Door: Use the provided template to mark the positions for drilling holes on the door face and edge. Ensure correct backset measurement.

Operating Instructions
Setting/Changing the Code:
The Codelocks CL410 is a mechanical lock, and its code is changed by repositioning internal pins. This process requires the lock to be removed from the door or partially disassembled. Refer to the detailed instructions provided with your code change kit.
- Remove Lock: Carefully remove the lock from the door, following the reverse of the installation steps.
- Access Code Chamber: Locate the code chamber on the rear of the front assembly.
- Change Pins: Using the code change kit, remove the existing code pins and insert new pins according to your desired code. Ensure the correct type of pin (code or non-code) is used for each slot.
- Reassemble and Test: Reassemble the lock and reinstall it on the door. Test the new code thoroughly before relying on it for security.
Note: The CL410 offers over 8000 possible code combinations. Keep your code confidential and change it periodically for enhanced security.
Unlocking the Door:
- Enter your valid code by pressing the corresponding buttons in sequence.
- Turn the lever/knob to retract the deadlatch bolt.
- Open the door.
Locking the Door:
The CL410 is a deadlatch, meaning it automatically locks when the door is closed and the latch bolt extends into the strike plate. No code entry is required to lock the door from the outside.
- Simply close the door. The deadlatch will engage automatically.
- From the inside, the door can typically be opened by turning the lever/knob without a code (passage function).
Maintenance
Regular maintenance ensures the smooth operation and extends the lifespan of your Codelocks CL410.
- Cleaning: Wipe the exterior surfaces with a soft, damp cloth. Avoid abrasive cleaners or solvents, as these can damage the finish.
- Lubrication: Periodically apply a small amount of silicone-based lubricant to the latch bolt and internal moving parts (if accessible) to ensure smooth operation. Do not use oil-based lubricants, as they can attract dust and grime.
- Inspection: Regularly check all fixing screws for tightness. Ensure the deadlatch mechanism operates freely and the strike plate is properly aligned.
- Code Change: Consider changing your access code periodically for enhanced security.
