Lishi 2-in-1 Pick/Decoder In-Depth Tutorial
Tip submitted by the Lishi manufacturer:
This 2-in-1 tool removes the need for spiking the lock after picking. Pick the lock open and the plug will turn only 5 degrees. Holding the lock in this position you can fully decode it. Once decoded, you can then remove the pick approx 1mm while still maintaining light turning tension. The plug will then turn 45 degrees to open the car.
