About C-HR Keys
Verified key reference for the Toyota C-HR — 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 |
|---|---|---|---|---|
| C-HR | 2018–2022 | Smart / proximity | DST-AES “H” / (A9) | TOY51 (insert) |
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 C-HR specifically we see: DST-AES “H” / (A9). A correctly cut but unprogrammed key turns the locks and never starts the engine — programming is the half of the job that matters.
Which key does your year have?
- 2018–2022: Smart / proximity — DST-AES “H” / (A9) (TOY51 (insert))

Toyota C-HR Key FAQ
I lost the only key to my C-HR. 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 C-HR is push-to-start — can you program that outside the dealer?
Yes. Late models (2018–2022) use a proximity smart key on DST-AES “H” / (A9) — we carry the fobs and the programmer, and we cut the emergency blade.
