1. Introduction
This manual provides detailed instructions for the proper use, maintenance, and care of your RLOKK LiShi HU66 v.3 2-in-1 Lock Pick and Decoder Tool. This professional-grade instrument is designed for skilled locksmiths to efficiently pick and decode automotive locks for vehicles primarily within the VW group (Volkswagen, Audi, Skoda, Seat, Porsche).
The tool combines two essential functions: a lock picking mechanism to manipulate internal lock components and a decoding scale to read the key bitting depths. Constructed from high-quality stainless steel, it offers durability and precision for professional applications.
2. Safety Information

4. Setup
Before using the LiShi HU66 v.3 tool, perform the following initial setup steps:
- Unpacking: Carefully remove the tool from its packaging. Inspect for any signs of damage during transit.
- Familiarization: Take time to familiarize yourself with the tool's components, including the tension wrench, picking needles, and decoding scale.
- Lubrication (Optional): For optimal performance, a very small amount of dry lubricant (e.g., graphite powder) can be applied to the internal moving parts of the tool, if necessary. Avoid liquid lubricants.
- Target Lock Identification: Confirm that the target lock is an HU66 profile, compatible with this tool.
5. Operating Instructions
Operating the LiShi HU66 v.3 requires skill, practice, and a thorough understanding of lock mechanisms. This section provides a general guide; specific techniques may vary based on the lock and individual preference.
5.1 Picking the Lock
- Insert the Tool: Gently insert the LiShi HU66 v.3 tool into the lock cylinder. Ensure it is fully seated.
- Apply Tension: Apply light, consistent rotational tension to the tool, mimicking the action of turning a key. The direction of tension depends on the lock's design (clockwise or counter-clockwise).
- Manipulate Wafers: Using the picking needles, individually manipulate the internal wafers of the lock. The goal is to set each wafer to its shear line while maintaining tension.
- Feel for Feedback: Pay close attention to tactile feedback. A slight click or movement indicates a wafer has been set. Continue this process for all wafers.
- Open the Lock: Once all wafers are set, the lock cylinder should rotate, allowing the lock to open.
5.2 Decoding the Lock
After successfully picking the lock, the tool can be used to decode the key bitting depths.
- Maintain Position: Keep the tool in the picked position (rotated).
- Read Depths: Carefully observe the decoding scale on the tool. Each picking needle corresponds to a specific bitting position. The markings on the scale will indicate the depth of each wafer.
- Record Bitting: Record the bitting depths for each position. This information can then be used to cut a new key.
- Remove Tool: Once decoding is complete, carefully remove the tool from the lock.
6. Maintenance
Proper maintenance ensures the longevity and reliable performance of your LiShi HU66 v.3 tool.
- Cleaning: After each use, gently wipe the tool with a clean, dry cloth to remove any dust, debris, or residue. Avoid using harsh chemicals or abrasive materials.
- Lubrication: If the internal mechanisms feel stiff, apply a minimal amount of dry lubricant (e.g., graphite powder) to the moving parts. Do not over-lubricate.
- Inspection: Regularly inspect the picking needles and decoding scale for any signs of wear, bending, or damage. Damaged components can affect performance and accuracy.
- Storage: Always store the tool in its original protective case when not in use. This protects it from physical damage, dust, and environmental factors. Store in a cool, dry place.
7. Troubleshooting
If you encounter issues while using the LiShi HU66 v.3, consider the following troubleshooting steps:
- Difficulty Picking:
- Ensure correct tension is applied. Too much or too little tension can prevent wafers from setting.
- Verify the tool is fully inserted and aligned with the lock's keyway.
- Confirm the lock is an HU66 profile.
- Practice on known locks to refine your technique.
- Inaccurate Decoding:
- Ensure the tool is held steady in the picked position while reading the depths.
- Check for any bending or damage to the decoding needles that might affect accuracy.
- Confirm proper lighting for clear reading of the scale.
- Tool Stiffness/Resistance:
- Clean the tool thoroughly to remove any accumulated debris.
- Apply a small amount of dry lubricant as described in the Maintenance section.
If problems persist, consult with experienced locksmiths or the tool manufacturer for further assistance.
