About CX-30 Keys
Verified key reference for the Mazda CX-30 — 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 |
|---|---|---|---|---|
| CX-30 | 2020–2025 | Smart proximity | NXP Hitag-AES / ID49 6A (PCF7953M) | MAZ24R emergency insert |
| CX-30 | 2020+ | Hitag AES / PCF7953M | BCYN-67-5RY |
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 CX-30 specifically we see: NXP Hitag-AES / ID49 6A (PCF7953M), BCYN-67-5RY. A correctly cut but unprogrammed key turns the locks and never starts the engine — programming is the half of the job that matters.

Mazda CX-30 Key FAQ
I lost the only key to my CX-30. 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 CX-30?
On transponder-era cars it opens doors and nothing else — the chip must be programmed to the immobilizer, which is what we do curbside.
