|---|---|---|---|---|
| MX-5 | 1995-1998 | Temic 12 / ID12 | TP04, TP05 / XT27 | |

Security System & Immobilizer
Mazda’s Ford-era cars share 4D63 PATS-style chips; later models moved to their own flip keys and today’s proximity fobs — the split matters for parts and programming, and we sort it by VIN.
On the MX-5 Miata specifically, the immobilizer families we see are: TP04, TP05 / XT27, T5 (TP05) / XT27, Temic Crypto 8C, TK5561 / XT27 / TP17, Texas 4D63 80-bit (ID63). 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.

Mazda MX-5 Miata Key FAQ
I lost the only key to my MX-5 Miata. 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 MX-5 Miata call.
Will a hardware-store copy start my MX-5 Miata?
It will open the doors and nothing else on transponder-era cars — the chip inside the key must be programmed to the immobilizer, which is the part we do curbside.
My MX-5 Miata is older — do you still stock keys for it?
Yes. We carry blanks and chips going back to the 1995-1998 generation (temic 12 / id12), and a code-cut fresh key usually turns a worn lock better than any copy of your worn key.
How fast can you reach my MX-5 Miata in DFW?
