The tool operates on the principle of mechanical feedback analysis. When tension is applied, the pins bind at the shear line between the plug and the housing, setting the stage for precise measurement and decoding.

• Ideal for situations where a heavily worn key and lock no longer function properly together. Decoding the lock in its current, worn state provides a code that reflects the actual pin positions. Cutting a new key to this "worn" code restores smooth operation.

• The tool transmits clear, real-time tactile information from the lock's pins directly to the user's hand. Simultaneously, the user receives visual confirmation via the moving pointer on the external scale, creating a dual-sensory feedback loop for enhanced precision.

• The external moving pointer serves as more than just a readout; its movement provides critical guidance. If it jumps erratically during your lift, your applied tension is likely incorrect and requires adjustment.
