Lishi Tools for American Cars: Ford, GM, Chrysler & Jeep Guide
Short version: there is no single Lishi tool for American cars. Ford mostly means HU101, GM splits between HU100 and its door-lock codes, and Chrysler/Jeep runs on CY24. Buy by keyway and lock position — not by the badge on the grille.
1. Why "one American tool" doesn't exist
Ford, GM and Stellantis do not share keyways, and they change codes inside the same model line. A 2017 Focus and a 2018 Focus can need different tools.
The tool is chosen by the code stamped on the key or read from the lock. Once you know the code, the decision is a lookup, not a judgement call.
2. Ford: HU101 first, then the exceptions
HU101 is the broadest Ford profile we carry: 10-cut, ignition, door and trunk, Ford and Jaguar. If you only buy one Ford tool, this is it.
The exceptions are specific. Older Ford and Lincoln locks use FO38. New Century, New Transit and Leopard CS10 doors use FORD2021. The 2018+ Focus uses HU198/FORD2017.
For the full breakdown by code, see the Ford keyway guide.
3. GM: door and ignition are different worlds
GM is the most fragmented of the three. HU100 v.3 covers a large share of Cadillac, Opel and Buick ignition, door and trunk locks — but Buick doors also appear as B111 and GM39, and Chevrolet Malibu/Captiva use CH1.
The version matters too. HU100 v.3 is 8-cut; newer Cadillac blades use the 10-cut HU100(10) v.3.
Most GM returns come from ordering one "GM tool" and meeting a Buick door that needs a different code. The GM keyway guide maps the six profiles we stock.
4. Chrysler and Jeep: CY24, with one generation trap
CY24 v.2 is the workhorse for Dodge, Jeep and Chrysler door locks: 7-cut.
CY24R-2021 is the 8-cut Jeep door profile for 2021-and-later vehicles. Same family name, different generation — check before you buy.
Jeep Compass and Fiat doors are a separate keyway: SIP22.
5. What a realistic starter kit looks like
Three tools cover most American work: HU101 for Ford, HU100 v.3 for GM, CY24 v.2 for Chrysler/Jeep. That is roughly $105 at current prices.
Add the door-lock and version-specific tools as jobs demand them: B111 for Buick doors, SIP22 for Compass, FO38 for older Fords.
Do not buy a "complete American set" before you know which vehicles you actually see.
| Family | Core tool | Exceptions to check |
|---|---|---|
| Ford | HU101 (10-cut) | FO38, FORD2021, HU198/FORD2017 |
| GM | HU100 v.3 (8-cut) | B111, GM39, CH1 v.2, HU100(10) v.3 |
| Chrysler / Jeep | CY24 v.2 (7-cut) | CY24R-2021 (8-cut), SIP22 |
6. What these tools won't do
They won't decode a different keyway, and they won't replace key programming. A 2-in-1 tool picks and reads depths; it does not program an immobiliser.
They also won't fix a worn lock. If the cylinder is damaged, decoding gives you a number that no longer matches the key.
7. Check before you order
Six fields decide the order: vehicle and model, year or generation, keyway code, lock position, cut count, tool version. The compatibility guide walks through them.
8. FAQ
Can one Lishi tool cover all Ford vehicles?
No. HU101 covers many Ford and Jaguar locks, but FO38, FORD2021 and HU198/FORD2017 exist because those keyways are different.
Is a 10-cut tool better than an 8-cut tool?
Neither. The cut count must match the lock. A 10-cut tool cannot decode an 8-cut keyway.
Why are GM door and ignition tools different?
Because GM used different keyway families for different lock positions. On GM, identify the position before the brand.
9. Where to start
Start with HU101, HU100 v.3 and CY24 v.2, then add the door-lock tools as they come up. The full range is in the American Vehicle collection.
