Setup: Setting Your Combination
Your Lewis N. Clark Triple Security Lock comes preset to 0-0-0. To set your personal combination, follow these steps:
- Ensure the lock is set to the current combination (factory default is 0-0-0).
- Locate the red reset button/lever on the side or back of the lock.
- Using a pen or a pointed object, press and hold the red reset button/lever. Some models may require you to slide or flip a red plastic piece.
- While holding the reset mechanism, rotate the dials to your desired 3-digit combination. Choose a memorable number.
- Release the reset button/lever. Your new combination is now set.
- Important: After setting the combination, ensure the red plastic piece (if applicable) is returned to its original position or removed from the reset slot to prevent accidental combination changes. Test your new combination by scrambling the dials and then entering your new code to open the lock.

Operating the Lock
The Lewis N. Clark Triple Security Lock offers multiple ways to secure your belongings:
- Opening the Lock: Align the dials to your set 3-digit combination. The cable ends will release from the lock body.
- Closing and Locking: Insert both cable ends firmly into the lock body until they click into place. Scramble the dials to secure the lock.
- Securing Zipper Pulls: Pass one or both cable ends through the zipper pulls of your luggage and then into the lock body.
- Locking to Fixed Objects: Use one cable end to secure your bag to a stationary object (e.g., a chair leg, luggage rack) and the other end to your bag's zipper pulls or handle, then insert both into the lock body.
- Adding a Bag: Secure smaller bags (laptop bag, purse, toiletry bag) to your main luggage by looping one cable end through the smaller bag's handle and the other through your main luggage's handle or zipper pulls, then lock.

Troubleshooting
If you encounter issues with your Lewis N. Clark Triple Security Lock, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Lock will not open with correct combination. | Dials are not precisely aligned; internal mechanism obstructed; combination accidentally changed. | Ensure each number is perfectly centered in the window. Gently wiggle the dials while attempting to open. If the combination was accidentally changed during reset, unfortunately, there is no master key or override. |
| Cables do not insert or release smoothly. | Dirt or debris in the cable slots; lack of lubrication; bent cable ends. | Clean the cable slots and cable ends. Apply a small amount of silicone lubricant. Ensure cables are not bent or damaged. |
| Combination changes unexpectedly. | Reset button/lever was accidentally pressed or not fully disengaged after setting. | Always ensure the reset mechanism is fully disengaged and returned to its locked position after setting a new combination. Be careful not to press it during normal operation. |
