Original Lishi 2-in-1 pick and decoder for SC1-L Schlage extended pin tumbler

lock. The -L designation indicates this is a LONG/EXTENDED version of the

standard SC1, providing additional reach for deep-set or recessed lock cylinders

that standard-length tools cannot access. SC1 is the Schlage profile — one of

the most widely used lock profiles in commercial and residential applications

in North America. This extended version is designed for cylinders recessed deep

within door frames, filing cabinets, or other installations where standard

tools cannot reach the pins. Combines picking and decoding in one professional-

grade locksmith instrument.

🔑 How to Use

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

 

1. Identify the lock — confirm SC1 profile and that extended reach is needed.

2. The -L extended design provides additional length for deep-set cylinders.

3. Insert the Lishi SC1-L 2-in-1 tool into the keyway — the extended reach allows access to pins in recessed housings.

4. Use the pick section to lift all pins to the shear line.

5. Switch to the decoder section to read pin depths and obtain the key code.

6. Generate or cut a key based on the decoded information.

7. Test the key in the lock and withdraw the tool.

(Extended picks are specifically for deep-set locks — use standard-length tools when possible.)

(Refer to official Lishi training materials for SC1 techniques and extended-pick usage.)

❓ Frequently Asked Questions (FAQ)

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

 

Q1: What does the "-L" mean in SC1-L?

A: The -L indicates LONG or EXTENDED version of the standard SC1 tool. It provides additional reach for deep-set or recessed lock cylinders where standard-length tools cannot access the pins. If your Schlage SC1 lock is installed deep within a door frame, filing cabinet, or other recessed housing, the SC1-L extended version is required.

 

Q2: When would I need SC1-L instead of standard SC1?

A: You need the extended SC1-L when the lock cylinder is recessed deep within the housing — common in thick door frames, high-security mortise locks, filing cabinets with deep cylinders, or any installation where standard-length Lishi tools cannot fully insert into the keyway. If standard SC1 reaches the pins comfortably, standard length is sufficient.

 

Q3: How is SC1-L different from the SC1 Replacement Tip (Product 159)?

A: Product 159 (SC1 Replacement Tip) is a replacement pick tip only — a spare part for worn or damaged SC1 tips. It is not a complete tool. SC1-L (this product) is a complete 2-in-1 pick and decoder in extended format — ready to use. Product 159 is for repairing an existing SC1 tool, not for new service work.

 

Q4: What is the SC1 profile?

A: SC1 is the Schlage standard pin tumbler profile — one of the most common lock profiles in North American commercial and residential locks. Schlage SC1 is used in a wide range of applications from deadbolts to knobs to mortise locks. The SC1 profile is widely cloned and used by multiple manufacturers under license.

 

Q5: Is SC1-L for automotive or commercial/residential locks?

A: SC1 is primarily a commercial and residential lock profile (Schlage), not typically automotive. However, some automotive applications may use Schlage-derived profiles in certain late-model vehicles. SC1-L is most commonly used for commercial door locks, filing cabinets, desk locks, and other non-automotive applications.

 

Q6: Can I use standard SC1 on a deep-set lock instead of SC1-L?

A: No — if the lock is deep-set and standard SC1 cannot reach the pins, you need SC1-L. Attempting to use a standard-length tool on a deep-set lock will result in incomplete pin access and inability to properly pick or decode the lock.

 

Q7: Do I need special training to use this tool?

A: Yes — this is a professional locksmith tool. Basic lock picking knowledge and familiarity with pin tumbler mechanisms is required. Extended picks require additional technique for proper insertion in recessed applications. Original Lishi offers official training programs.

 

Q8: What is the return policy?

A: Locksmith Mall offers a 1-Year Free Return if the tool does not match your lock type or arrives defective. Verify lock compatibility (confirm SC1 profile and depth requirement) before ordering.
