The Lishi 2-in-1 tool allows an entry technician to manipulate individual pins/tumblers and carefully identify each chamber in the lock that is being accessed. Once a pin has been successfully set, the bitting depth can be read and decoded using the gauge printed on the tool.
This version of the Lishi 2-in-1 tool is shaped with the profile of Schlage's most common Everest Classic keyway profile, the C123.
Video of this tool being used can be seen here.
NOTE: all Lishi 2-in-1decoder picks sold by Red Team Tools now come with a free 0.153" Standoff Spacer Adapter to allow 6-pin Schlage and Kwikset Lishi tools to be used in 5-pin Schlage and Kwikset locks. More information about this tool can be seen in this video... https://www.youtube.com/watch?v=bDstfXbIAAY ...and the Standoff Spacer Adapter is also available separately on our site. (Technically, all Schlage Everest locks are 6-pin but this standoff spacer tool is included free to all who purchase any style of Lishi decoder pick from Red Team Tools. We give them away with our Lishi picks because we like you. :-)
