The Lishi tool is fundamentally a non-destructive entry (NDE) tool. When used correctly, it does not damage the internal components of the lock and leaves no forensic evidence of manipulation.

• When installing an aftermarket lock cylinder, a technician can use the Lishi to decode it and ensure its pinning matches the provided key or the system it's being integrated into, catching potential errors before installation.

• Despite its advanced design, effective use requires significant training and a developed sense of touch. The integrated design naturally encourages users to apply smooth, consistent tension—a fundamental skill in lock manipulation.

• If a pin feels "dead" or mushy with no click, you may have lifted it too high. Release tension completely to reset all pins and begin again with a lighter touch.
