Subaru Legacy Key Replacement
Subaru Legacys have been on Dallas–Fort Worth roads since the 1998 era, and across 5 key generations this model has used 3 different key systems — transponder key; remote head / transponder key; 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 Legacy Keys
The table below is our verified key reference for the Subaru Legacy — 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 |
|---|---|---|---|---|
| Legacy | 1998–2004 | Transponder key | Texas Crypto 4D / ID4D60 | older Subaru keyway |
| Legacy | 2005–2009 | Transponder key | Texas Crypto 4D / ID4D62 (DST80) | DAT17 high-security (2008+) / older pre-’08 |
| Legacy | 2010–2014 | Remote head / transponder key | 4D62 (DST80) | DAT17 high-security |
| Legacy | 2015–2019 | Smart proximity (push-to-start) | DST-4D “G” board | DAT17 emergency insert |
| Legacy | 2020–2024 | 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 Legacy specifically, the immobilizer families we see are: Texas Crypto 4D / ID4D60, Texas Crypto 4D / ID4D62 (DST80), 4D62 (DST80), DST-4D “G” board, 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 Legacy Key FAQ
I lost the only key to my Legacy. 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 Legacy call.
My Legacy is push-to-start. Can you really program that outside the dealer?
Yes. Late-model Legacys (2020–2024) 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 Legacy is older — do you still stock keys for it?
Yes. We carry blanks and chips going back to the 1998–2004 generation (transponder key), and a code-cut fresh key usually turns a worn lock better than any copy of your worn key.
