🔑 Original Lishi 2-In-1 Pick and Decoder SC4 LFIC — GM / Ford
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
📦 PRODUCT DESCRIPTION
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
The Original Lishi 2-In-1 Pick and Decoder SC4 LFIC is a factory-original
Lishi tool designed for GM and Ford vehicles using the SC4 large-format
interchangeable core (LFIC) keyway. It combines a tension pick and a
bit-reading decoder in one stainless steel instrument — letting you both
open the LFIC lock and originate a new key without swapping tools. The SC4
LFIC is a common keyway in commercial and fleet applications, including
GM vans, Ford E-Series, and various work trucks where large-format
interchangeable cores are used for master-keyed systems.

🚗 COMPATIBILITY
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

⚠️ Always verify your keyway is SC4 LFIC before ordering. LFIC cores are
physically larger than standard automotive cores — confirm the key bow
is stamped SC4 or matches a Lishi SC4 reference chart.

🔧 PROGRAMMING
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
⚠️ No programming required — this is a mechanical pick + decoder tool, not an electronic device.
📖 How to use: Insert the 2-in-1 tool into the LFIC lock cylinder, apply
light tension with the pick end to release the core's pin stack, then
read the bit depths across the tool spaces. Translate the readings to a
cuts code, then cut a new SC4 key blank on a precision key-cutting
machine.
🏭 Recommended: Use HPC CodeMax, Silca Quattroplus, or Advanced Diagnostics
MXP code cutter with a SC4-compatible LFIC key blank.
⚠️ Most GM / Ford vehicles from 1996+ use transponder keys. After cutting
the new mechanical key, you will also need to program the transponder
chip (PK3, TEX, or 4D63 depending on year) using a compatible
immobilizer programmer.

❓ FREQUENTLY ASKED QUESTIONS
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Q1: Is this an original Lishi tool or a knockoff?
A: ✅ 100% genuine Original Lishi 2-in-1, sourced from authorized Lishi
distributors. Ships with authenticity card and Lishi serial marking.
Q2: What does "LFIC" mean?
A: ✅ LFIC = Large Format Interchangeable Core. These are larger removable
cores commonly used in commercial / fleet / master-keyed systems. The
SC4 is a specific keyway profile for GM and Ford LFIC applications.
Q3: Which GM and Ford vehicles use the SC4 LFIC keyway?
A: ✅ The SC4 LFIC is found in GM commercial vans and work trucks
(1990s–2010s), Ford E-Series vans, F-Series fleet trucks, and similar
commercial applications. Always verify the keyway stamp on the key bow
before ordering.
Q4: Do I need a working key to use this tool?
A: ✅ No. The 2-in-1 design lets you pick the LFIC lock open first, then
decode the bitting from inside — no working key required.
Q5: After cutting the new key, do I need to program anything?
A: ⚠️ Yes — most 1996+ GM / Ford vehicles use transponder keys (PK3, TEX,
4D63 depending on year). You will need a separate immobilizer
programming tool to add the new transponder chip to the vehicle.
Q6: Is the SC4 LFIC tool the same as the regular SC4 tool?
A: ❌ No. The LFIC version is specifically designed for large-format
interchangeable cores (physically larger cylinders). Using a standard
SC4 tool on an LFIC core will not work. Confirm LFIC before ordering.
Q7: Can this tool re-pin an LFIC core?
A: ❌ No. This is a pick + decoder tool. To re-pin an LFIC core you need
pinning tweezers, a pinning mat, and a LFIC follower. Many locksmiths
pair the Lishi SC4 LFIC with a dedicated LFIC pinning kit.
Q8: How long does it take to pick an LFIC lock?
A: ⚠️ LFIC cores are larger and have more pins than standard wafer locks,
so picking typically takes 5–10 minutes for an experienced Lishi user.
New users should allow 30–60 minutes of practice on a junkyard lock.
