❓ Frequently Asked Questions (FAQ)
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Q1: What locks are compatible with the Lishi SC20 tool?
A: The Lishi SC20 is designed for Schlage L series keyways including SC20 and A1145L.
It is also compatible with Schlage L master multiple keyways including SC4. This tool
is used for residential and commercial door lock applications. Always verify your lock
keyway matches the SC20 profile before ordering.
Q2: What does "depths 0-9" mean on the SC20 Lishi tool?
A: The SC20 Lishi has 10 depth settings ranging from 0 to 9, allowing for precise pin
depth reading across the 6 tool spaces. This wide range of depths makes it suitable
for master key systems where different depths are used for different levels of keys.
Q3: What is the difference between SC20 and SC4 keyways?
A: The SC20 and SC4 are both Schlage L series keyways used in master key systems.
The SC20 is the primary keyway covered by this Lishi tool, and it also supports the
SC4 as a compatible master keyway within the same series.
Q4: Is this tool for automotive or residential locks?
A: The Lishi SC20 is designed for residential and commercial door lock applications —
specifically Schlage L series mortise or cylinder locks. It is not for automotive locks.
Q5: Can I use this tool to program a new key?
A: No. This is a mechanical decoding tool only. It helps you cut a physical key to the
correct depths. Programming electronic locks or smart keys requires separate equipment.
Q6: What does "Schlage L master multiple keyways" mean?
A: Schlage L series is a master key system used in commercial and residential applications
where multiple keys operate the same lock at different levels of authorization.
Q7: Is this an original Lishi tool?
A: Yes. This product is sourced as original Lishi factory tooling and carries the Lishi logo.
Q8: What is the return policy?
A: Locksmith Mall offers a 1-year free return on all products. If the tool is defective
or does not match your lock, contact us for a replacement or refund.
