Subaru Impreza Key Replacement
Subaru Imprezas have been on Dallas–Fort Worth roads since the 2001 era, and across 4 key generations this model has used 3 different key systems — transponder key; transponder / smart (trim-dependent); smart proximity (push-to-start). Whichever yours is, DFW Keys 4 Cars cuts and programs it at your location, 24/7: spare keys, lost-everything replacements, fob programming, and lockouts. Call (214) 717-6398.
About Impreza Keys
The table below is our verified key reference for the Subaru Impreza — model years, key types, and the transponder/immobilizer family each generation uses. Generations overlap at boundary years, and trim levels (keyed vs. push-to-start) can differ within the same year, so we always confirm the exact part by VIN before dispatching.
| Model / Generation | Years | Key Type | Transponder / Immobilizer | Blade / FCC |
|---|---|---|---|---|
| Impreza | 2001–2003 | Transponder key | Texas Crypto 4D / ID4D60 | older Subaru keyway |
| Impreza | 2004–2010 | Transponder key | Texas Crypto 4D / ID4D62 (DST80) | DAT17 high-security (2008+) / older pre-’08 |
| Impreza | 2012–2016 | Transponder / smart (trim-dependent) | 4D62 (DST80) | DAT17 high-security |
| Impreza | 2017–2023 | Smart proximity (push-to-start) | 8A / DST-AES | DAT17 emergency insert |
Security System & Immobilizer
Subaru moved through 4D62 and G-chip transponders to H-chip keys and proximity smart fobs on current models — all field-programmable with the right tools.
On the Impreza specifically, the immobilizer families we see are: Texas Crypto 4D / ID4D60, Texas Crypto 4D / ID4D62 (DST80), 4D62 (DST80), 8A / DST-AES. A key that is cut correctly but not programmed to this system will turn the locks and never start the engine — programming is the half of the job that matters.

Subaru Impreza Key FAQ
I lost the only key to my Impreza. 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 — this is our most common Impreza call.
My Impreza is push-to-start. Can you really program that outside the dealer?
Yes. Late-model Imprezas (2017–2023) use a proximity smart key on the 8A / DST-AES system — our trucks carry the fobs and the programmer. We cut the emergency blade too.
My Impreza is older — do you still stock keys for it?
Yes. We carry blanks and chips going back to the 2001–2003 generation (transponder key), and a code-cut fresh key usually turns a worn lock better than any copy of your worn key.
