Lishi SC4-AG-6 PINS Original Tool

The Lishi SC4-AG-6 Pins Original Tool is a precision-manufactured 2-in-1 tool designed for non-destructive opening and decoding of Schlage lock cylinders using the SC4 key profile. This profile is widely used in North American residential and light commercial applications and features six pin tumblers without an additional sidebar.

The tool combines the proven Lishi mechanism with a clearly structured and easy-to-read scale, supporting accurate probing and positioning of each pin. Especially in six-pin cylinders, the defined scale simplifies evaluation of varying depths and pin combinations. Direct tactile feedback allows precise interpretation of the cylinder’s internal state and enables controlled work without additional aids.

The AG version stands for Anti-Glare. The matte, non-reflective surface reduces distracting light reflections and significantly improves readability of the depth markings, particularly in bright working environments. Made from robust stainless steel, the tool maintains its shape and functional reliability even under continuous professional use.

The Schlage SC4 profile is commonly found in U.S. households as well as smaller commercial properties. For skilled users who regularly work with these six-pin standard cylinders, the SC4-AG-6 Pins Original Tool is a practical addition, enabling a structured and traceable working method directly at the cylinder.
