About STI Keys
Verified key reference for the Subaru STI — 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 |
|---|---|---|---|---|
| WRX / STI | 2008–2014 | Transponder / remote head | 4D62 (DST80) | DAT17 high-security |
| WRX / STI | 2015–2021 | Smart proximity (push-to-start) | DST-4D “G” board → 8A / DST-AES | DAT17 emergency insert (confirm by VIN) |
Security System & Immobilizer
Subaru moved through 4D62 and G-chip transponders to H-chip keys and proximity smart fobs.
On the STI specifically we see: 4D62 (DST80), DST-4D “G” board → 8A / DST-AES. 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?
- 2008–2014: Transponder / remote head — 4D62 (DST80) (DAT17 high-security)
- 2015–2021: Smart proximity (push-to-start) — DST-4D “G” board → 8A / DST-AES (DAT17 emergency insert (confirm by VIN))

Subaru STI Key FAQ
I lost the only key to my STI. 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 STI is push-to-start — can you program that outside the dealer?
Yes. Late models (2015–2021) use a proximity smart key on DST-4D “G” board → 8A / DST-AES — we carry the fobs and the programmer, and we cut the emergency blade.
