🔑 How to Use

1. Identify the lock profile — confirm it uses C123 or S123 (both covered by this tool).

2. Insert the Lishi 2-in-1 tool with picks facing upward into the keyway.

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

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

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

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

(The dual-profile design allows the same tool to work on both C123 and S123 locks.)

❓ Frequently Asked Questions (FAQ)

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

 

Q1: What is the difference between C123 and S123?

A: C123 and S123 are related but distinct pin tumbler lock profiles. C123 is commonly associated with certain commercial lock manufacturers; S123 is another profile variant. They are similar in design but have subtle differences in pin count, spacing, or keyway shape. This Lishi tool is designed to work on both profiles — convenient for locksmiths who encounter either.

 

Q2: Why is this a dual-profile tool?

A: Some lock manufacturers use variations of the same basic profile, and a dual-profile tool provides coverage for multiple related profiles in one instrument. Having a C123 / S123 dual-profile tool means you don't need to carry two separate tools when you might encounter either profile on the job. It's a practical approach for working locksmiths.

 

Q3: Is this tool for automotive or commercial locks?

A: C123 and S123 are commercial and residential lock profiles — not automotive. This tool is used for commercial door locks, master key systems, and residential lock service in non-automotive contexts. For automotive locks, Lishi offers a separate range of profiles.

 

Q4: How is this different from SC1 (Product 174)?

A: SC1 (Product 174) is the Schlage SC1 profile — a different lock profile from C123 and S123. SC1 is one of the most common residential/commercial profiles in North America. C123 and S123 are separate profiles with different keyway geometries and pin configurations. They are not interchangeable.

 

Q5: Can I use this tool on a Schlage lock?

A: No — C123 / S123 is not the Schlage SC1 profile. If you need to work on Schlage SC1 locks, use Product 174 (SC1-L extended version or standard SC1). C123 / S123 is a different profile — always verify the lock's profile code before purchasing.

 

Q6: Do master key systems commonly use C123 or S123?

A: Yes — C123 and S123 profiles are often found in master key systems for commercial buildings, hotels, and office complexes. A locksmith working on master key systems frequently encounters these profiles. The dual-profile tool provides efficient coverage for both.

 

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. Commercial lock picking may involve master pinning and more complex cylinder configurations. 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 C123 or S123 profile) before ordering.
