Lishi SC20 Schlage 6-Pin Pick and Decoder
Description
Description
The Broader Schlage Classic C Choice
The Lishi SC20 is a keyway-specific lock pick and decoder for matching Schlage SC20 and Classic C profile 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 SC20, not guesswork
The job
Use this tool when the lock profile matches SC20 and you want guided pin feedback plus decoding in one tool.
The fit
Lishi SC20 Schlage 6-Pin Pick and Decoder is for matching Schlage SC20 and Classic C profile 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.
How to tell if SC20 is the right Schlage tool
Check the Schlage C profile
SC20 is for matching Schlage SC20 and Classic C profile cylinders. Look at the key blade grooves and the front of the plug, not just the name on the lock.
Know the pin count
This page is the six-pin Schlage route. If you are holding a five-cut SC1 key, use the SC1 Lishi; if the profile is a narrower SC4-only job, compare the SC4 page.
Use the product photos
Compare the keyway diagram and tool shape with your cylinder before ordering. If the tool cannot enter the keyway cleanly, the grid cannot give useful feedback.
Confirm the profile, then work slowly
A Lishi is not a universal rake. Confirm the SC20 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 SC20 keyway before ordering.
- Start with light tension and deliberate movement.
- If you have the five-pin SC1 profile, use the SC1 tool; if you want the narrower six-pin SC4 route, compare the SC4 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.
Quick answers from the LockPickWorld bench
What is this used for?
It is used to pick and decode matching Schlage SC20 and Classic C profile cylinders with one keyway-specific tool.
How do I know if it fits my lock?
Confirm the keyway is the Schlage SC20 or Classic C profile, check that you are working with the six-pin route, then compare the keyway diagram with your plug face.
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 SC20 Lishi to your bench
Choose it when your key and cylinder match the Schlage SC20 or Classic C six-pin profile and you want guided pin feedback plus decoding practice in one tool.
