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.

Which key does your year have?

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.
