❓ Frequently Asked Questions (FAQ)
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Q1: What is the Schlage SC4 keyway and what locks use it?
A: The Schlage SC4 is a 6-pin keyway used in Schlage brand residential and
commercial door locks. It is one of the most common keyways in North America for
exterior and interior door locks. The SC4 Lishi tool allows locksmiths to pick
and decode these locks accurately for key duplication.
Q2: What are spool pins and why does this tool matter?
A: Spool pins (also called security pins) are a lock pinning technique that uses
spool-shaped driver pins that create a false set sensation during picking,
increasing pick resistance. The Lishi SC4 tool is designed to work on locks
that use spool pins, allowing accurate decoding despite this security feature.
Q3: How is the SC4 different from the SC20 or SC1?
A: The SC4 is a 6-pin Schlage keyway (like the KW1). The SC1 is a 5-pin version.
The SC20 is a different keyway family (Schlage L series) also with 6 pins. The SC4
and SC1 are the most common residential Schlage keyways, while SC20/L series is
for master key systems. They are not interchangeable.
Q4: Is this tool for automotive or door locks?
A: The Lishi SC4 is designed for residential and commercial door lock applications —
specifically Schlage SC4 cylinder locks. It is NOT for automotive locks.
Q5: Can I use this tool to make a master key?
A: The SC4 Lishi can decode individual pins to help you cut a key to the correct
depths. Creating a true master key system requires understanding the master pin
configuration in the lock.
Q6: Why is this restricted to licensed locksmiths?
A: Professional-grade pick and decode tools have legitimate locksmith applications
but can be misused. Locksmith Mall restricts this product to licensed professionals.
Q7: Is this an original Lishi tool?
A: Yes. Sourced as original Lishi factory tooling with the Lishi logo.
Q8: What is the return policy?
A: Locksmith Mall offers a 1-year free return on all products.
