3. Operating Instructions
The KW1 LiShi tool is designed for both picking and decoding Kwikset civil locks. Proficiency requires practice and a thorough understanding of lock mechanisms.
3.1. Understanding Tooth Positions and Depths
The tool features 5 distinct tooth positions and 6 possible tooth depths. The depth scale typically ranges from 1 (deepest) to 6 (shallowest). Accurate reading of these depths is essential for creating a key or understanding the lock's bitting.
3.2. Picking a Kwikset Lock
- Insert the Tool: Carefully insert the KW1 LiShi tool into the Kwikset lock's keyway, ensuring it is fully seated.
- Apply Tension: Apply light, consistent tension to the tension wrench (not included) in the direction of opening.
- Pick the Pins: Using the picking blade of the tool, gently manipulate each pin, feeling for the binding pin. Apply slight pressure to set the pin. Repeat this process for all pins until the lock opens.
- Maintain Feedback: Pay close attention to the tactile feedback from the tool. A slight "click" indicates a pin has been set.
3.3. Decoding a Kwikset Lock
- Insert and Set: Insert the tool into the lock and pick it open as described above. Once the lock is open, maintain light tension.
- Read Depths: With the lock in the open position, carefully read the depth of each pin using the markings on the tool. The tool's design allows for direct reading of the bitting.
- Record Bitting: Note down the depth for each of the 5 tooth positions. This sequence represents the lock's bitting code.
- Remove Tool: Once decoding is complete, carefully remove the tool from the lock.

4. Maintenance
Proper maintenance ensures the longevity and continued precision of your KW1 LiShi tool.
- Cleaning: After each use, wipe the tool with a clean, dry cloth to remove any dust, debris, or residue. Avoid using abrasive cleaners or solvents that could damage the stainless steel finish or markings.
- Lubrication: The tool generally does not require lubrication. If any moving parts feel stiff, a very small amount of dry lubricant (e.g., graphite powder) can be applied, but avoid over-lubrication.
- Storage: Store the tool in a protective case or pouch to prevent bending, scratching, or damage to the delicate picking and decoding tips. Keep it in a dry environment to prevent corrosion.
- Inspection: Regularly inspect the tool for any signs of wear, especially on the picking blades and decoding scale. Replace the tool if significant wear or damage is observed, as this can affect accuracy and performance.
5. Troubleshooting
If you encounter issues while using your KW1 LiShi tool, consider the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Difficulty picking the lock. | Incorrect tension applied, worn pins in the lock, or lack of practice. | Adjust tension, ensure the tool is fully inserted, and practice on different locks to improve technique. |
| Inaccurate decoding readings. | Tool not fully engaged, debris in the lock, or misreading the scale. | Ensure the tool is properly seated and the lock is fully open. Clean the lock if necessary. Double-check readings against the scale. |
| Tool feels stiff or gritty. | Accumulation of dirt or debris. | Clean the tool thoroughly. If necessary, apply a minimal amount of dry lubricant. |
If problems persist, consider consulting with an experienced locksmith or contacting the product manufacturer for further assistance.
