About Solara Keys
Verified key reference for the Toyota Solara — 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 |
|---|---|---|---|---|
| Solara | 1999–2003 | Transponder (cut) | Texas 4C (non-crypto) | TOY43 |
| Solara | 2004–2008 | Transponder (cut) | Texas 4D67 “Dot” (DST40) | TOY43 |
Security System & Immobilizer
Toyota’s immobilizer evolved through four transponder families — Texas 4C, the 4D67 “dot” chip, the DST80 “G” chip, and today’s 128-bit “H” chip — before the Smart Key System brought push-to-start proximity fobs.
On the Solara specifically we see: Texas 4C (non-crypto), Texas 4D67 “Dot” (DST40). A correctly cut but unprogrammed key turns the locks and never starts the engine — programming is the half of the job that matters.

Toyota Solara Key FAQ
I lost the only key to my Solara. 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 Solara?
On transponder-era cars it opens doors and nothing else — the chip must be programmed to the immobilizer, which is what we do curbside.
