Work the SC4 Keyway With a Decoder Grid
The Lishi SC4 is a keyway-specific lock pick and decoder for matching 6-pin Schlage SC4 cylinders. It gives you guided pin-by-pin feedback while you pick, then a decoder grid for reading depths after the plug turns. Match the keyway first, then let the tool teach the feel.

Made for Schlage SC4, not guesswork
The job
Use this tool when the lock profile matches SC4 and you want guided pin feedback plus decoding in one tool.
The fit
Lishi SC4 Schlage 6-Pin Pick and Decoder is for matching 6-pin Schlage SC4 cylinders. Brand name alone is not enough. Match the keyway profile.
The route in
Start on known practice hardware, keep tension light, and move one numbered position at a time so the feedback stays readable.
One keyway, two useful jobs
Lishi tools are strongest when chosen precisely. The pick surface helps you work the pins in order, while the scale gives you a repeatable way to read the lock after successful movement.

Confirm the profile, then work slowly
A Lishi is not a universal rake. Confirm the SC4 profile, insert the tool cleanly, apply controlled tension, and test the numbered pin positions one at a time. When the plug turns, use the grid to read the depth information the tool is designed to show.
- Match the exact SC4 keyway before ordering.
- Start with light tension and deliberate movement.
- For broader Schlage Classic C coverage, compare the SC20 tool.

Pair it with the Beginners Visual Guide
Lishi tools make more sense when you understand binding order, tension, the shear line, and why pin positions feel different. The Beginners Visual Guide gives you 178 pages and 190+ full-color illustrations, including Lishi tool concepts in the wider lock picking toolkit.
Keep the guide next to your practice lock while you learn what the grid is showing. It is a separate companion, not part of this tool, and it gives newer pickers a friendlier route into precise keyway work.
Chris Dangerfield, founder: A Lishi rewards patience. The tool is clever, but the real value is that it slows the lock down for you. Match the keyway, keep your tension clean, and use the grid as a way to understand what your hands just felt.

These independent videos give a clearer visual sense of how the SC4 tool is handled and why the decoder grid is useful once the profile matches.

Quick answers from the LockPickWorld bench
What is this used for?
It is used to pick and decode matching 6-pin Schlage SC4 cylinders with one keyway-specific tool.
How do I know if it fits my lock?
Match the keyway profile first. If the cylinder is not SC4, choose the Lishi made for that profile instead.
Is this approachable while I am learning?
Yes, if you start on known practice hardware and take it slowly. The grid can make pin positions easier to understand than freehand picking alone.
What should I pair it with?
Use a matching practice cylinder if you have one, a standard pick set for freehand work, and the Beginners Visual Guide when you want the mechanism explained visually.
Add the SC4 Lishi to your bench
Choose it when the keyway matches and you want one focused tool for guided picking feedback, decoding practice, and cleaner Schlage SC4 learning sessions.
