About SC 430 Keys
Verified key reference for the Lexus SC 430 — model years, key types, and the transponder/immobilizer each generation uses. Boundary years can overlap; we confirm the exact part by VIN before dispatching.
| Model / Generation | Years | Key Type | Transponder / Immobilizer | Blade / FCC |

| SC 430 | 2002–2010 | Transponder / remote-head key | Texas Crypto 4D (4D68, DST80 “G”) | TOY48 |
Security System & Immobilizer
Lexus shares Toyota’s immobilizer lineage — 4C, 4D67, G and H transponder eras — topped by Smart Access proximity fobs on push-to-start models.
On the SC 430 specifically we see: Texas Crypto 4D (4D68, DST80 “G”). A correctly cut but unprogrammed key turns the locks and never starts the engine — programming is the half of the job that matters.

Lexus SC 430 Key FAQ
I lost the only key to my SC 430. What now?
We come to the vehicle, verify ownership, cut a new key from the VIN, and program it on-site — no tow, no dealer wait.
Will a hardware-store copy start my SC 430?
On transponder-era cars it opens doors and nothing else — the chip must be programmed to the immobilizer, which is what we do curbside.
