Setup and Installation

Initial Code Setting
The lock is supplied with random, unrecorded codes. It is crucial to change the factory-set code immediately after installation for security purposes. Follow the instructions below to set your new access code:
- Locate the code change pins on the back of the keypad unit.
- Using a small screwdriver or the provided tool, rotate the pins corresponding to your desired code numbers to the 'ON' position.
- Ensure all other pins are in the 'OFF' position.
- Test the new code multiple times with the door open before closing and locking the door.
- Keep a record of your new code in a secure location.
For detailed visual guides on installation and code changing, please refer to the manufacturer's official documentation or support website.
Operating Instructions
External Access (Code Entry)
- Enter your programmed code by pressing the corresponding buttons on the keypad. The order of buttons matters.
- After entering the correct code, turn the external lever handle to retract the latch bolt and open the door.
- The latch bolt will automatically re-lock when the door is closed.
Internal Exit (Anti-Panic Function)
- From the inside, simply push down the internal lever handle.
- The anti-panic safety function allows immediate retraction of both the deadbolt (if projected) and the latch bolt, enabling quick exit without needing a code or key.
Key Override and Deadbolt Control
- Insert one of the provided keys into the cylinder.
- Turning the key will retract the latch bolt for entry without requiring a code.
- The key also controls the position of the deadbolt. When the deadbolt is projected (locked), code access is denied, providing enhanced security.
- Keys can be used for management functions, such as allowing access for cleaning staff or security personnel without sharing the code.
Code-Free Option
The CL525 may feature a code-free option, allowing the lock to remain unlocked for periods of high traffic. Consult your specific model's instructions for how to engage and disengage this function, typically involving a specific key turn or button sequence.
Maintenance
Regular maintenance will ensure the longevity and reliable operation of your Codelocks CL525.
- Cleaning: Wipe the lock's exterior surfaces with a soft, damp cloth. Avoid using abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish and internal components.
- Lubrication: Periodically, a small amount of silicone-based lubricant can be applied to the latch bolt and deadbolt mechanisms to ensure smooth operation. Do not use oil-based lubricants, as they can attract dust and debris.
- Inspection: Regularly check for any loose screws, excessive play in the handles, or signs of wear. Address any issues promptly to prevent further damage.
- Key Care: Keep keys clean and free from debris. Do not force keys into the cylinder if they feel stiff.
