AKK Yale-5B is a Lishi Style 2-in-1 Pick & Decoder for YALE 5-Pin Euro Lock Cylinder.
It’s not Lishi branded, nor it’s made by Mr. Li. The manufacturer has the same design concept with Mr. Li’s original tools. Each tool is inserted into a vehicle lock and used to pick the lock to a position where it traps the wafers. The wafer depth can then be read to determine the cuts for a replacement key.
