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 compatible with Lockwood A-keyed locks that accept 6-pin LW5 blanks. (Although it also works in many 5-pin Lockwood locks, depending on the tail side configuration)
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 Lishi tools to be used in 5-pin locks. More information about this tool can be seen in this video... https://www.youtube.com/watch?v=Y023QVd8pvY ...and the Standoff Spacer Adapter is also available separately on our site. (This tool is included free to all who purchase any style of Lishi decoder pick from Red Team Tools, but it is was originally designed for use with Schlage and Kwikset tools. We give them away with other Lishi picks, however, because we like you. :-)
