Lishi - Masterlock (M1)

Pick it. Decode it. Move on.

The Original Lishi 2-in-1 tool combines picking, tensioning, and decoding into a single precision instrument. Graduated lines along the side of the tool put pick tip placement on autopilot, and once the cylinder opens, the same tool reads the bitting values directly so you can cut a working key without guesswork.

This variant is cut for the M1/MS2 keyway, the 4-pin profile used by Master Lock padlocks and compatible hardware from several other manufacturers.
