About tC Keys
Verified key reference for the Scion tC — 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 |
|---|---|---|---|---|
| tC | 2005–2010 | Remote head key (MOZB41TG) | Texas 4D67 “Dot” (DST40) | TOY43 (TR47 / TOY44D) |
| tC | 2011–2016 | Remote head key (MOZB41TG) | DST80 “G” chip — confirm Dot vs G by VIN | TOY43 (TR47) |
| tC | 2011–2016 | Smart key / proximity, push-button start (HYQ14ACX) | DST80 “G” (Toyota Smart) | TOY48 / TOY51 emergency insert |
Security System & Immobilizer
Scions use Toyota’s immobilizer families of their era — mostly 4D67 dot and G chips — with parts and programming still readily available.
On the tC specifically we see: Texas 4D67 “Dot” (DST40), DST80 “G” (Toyota Smart). A correctly cut but unprogrammed key turns the locks and never starts the engine — programming is the half of the job that matters.

Scion tC Key FAQ
I lost the only key to my tC. 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.
My tC is push-to-start — can you program that outside the dealer?
Yes. Late models (2011–2016) use a proximity smart key on DST80 “G” (Toyota Smart) — we carry the fobs and the programmer, and we cut the emergency blade.
Do you still stock keys for older tCs?
Yes — back to the 2005–2010 generation (remote head key (mozb41tg)), and a fresh code-cut key beats any copy of a worn original.
