About RX-8 Keys
Verified key reference for the Mazda RX-8 — 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 |
|---|---|---|---|---|
| RX-8 | 2003–2012 | Transponder (mechanical key) | Texas 4D63 80-bit (ID63) | MAZ24R (laser) |
| RX-8 | 2003-2012 | Texas Crypto 4D+ 80bit / ID63-6F | Tiris DST+ (DST80) |
Security System & Immobilizer
Mazda’s Ford-era cars share 4D63 PATS-style chips; later models moved to their own flip keys and proximity fobs.
On the RX-8 specifically we see: Texas 4D63 80-bit (ID63), Tiris DST+ (DST80). A correctly cut but unprogrammed key turns the locks and never starts the engine — programming is the half of the job that matters.

Mazda RX-8 Key FAQ
I lost the only key to my RX-8. 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.
Will a hardware-store copy start my RX-8?
On transponder-era cars it opens doors and nothing else — the chip must be programmed to the immobilizer, which is what we do curbside.
