This professional tool operates on mechanical feedback analysis principles. When tension is applied, the pins bind at the shear line between the plug and housing, enabling precise measurement and decoding.

• Taxi companies managing multiple vehicles frequently encounter lost or unreturned driver keys. The Lishi tools enable in-house mechanics or locksmiths to generate replacement keys quickly, minimizing vehicle downtime and maintaining revenue generation.

• Dual-sensory feedback system transmits clear, real-time tactile information from lock pins directly to the user's hand while providing visual confirmation via the moving pointer on the external scale.

• Successful decoding requires a calm, focused, and patient approach. Avoid frustration, rushing, or distractions. Maintain steady breathing and concentration throughout the process.
