Mazda CX-7 Key Replacement
Mazda CX-7s have been on Dallas–Fort Worth roads since the 2006 era, and across 2 key generations this model has used 2 different key systems — texas crypto 4d+ 80bit / id63-6f; transponder / smart proximity. 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 CX-7 Keys
The table below is our verified key reference for the Mazda CX-7 — 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 |
|---|---|---|---|---|
| CX-7 | 2006-2013 | Texas Crypto 4D+ 80bit / ID63-6F | Tiris DST+ (DST80) | |
| CX-7 | 2007–2012 | Transponder / smart proximity | Texas 4D63 80-bit (ID63) | MAZ24R (laser) |
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 CX-7 specifically, the immobilizer families we see are: Tiris DST+ (DST80), 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.
Which key does your year have?
- 2006-2013: Texas Crypto 4D+ 80bit / ID63-6F — Tiris DST+ (DST80)
- 2007–2012: Transponder / smart proximity — Texas 4D63 80-bit (ID63) (MAZ24R (laser))

Mazda CX-7 Key FAQ
I lost the only key to my CX-7. 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 CX-7 call.
My CX-7 is push-to-start. Can you really program that outside the dealer?
Yes. Late-model CX-7s (2007–2012) use a proximity smart key on the Texas 4D63 80-bit (ID63) system — our trucks carry the fobs and the programmer. We cut the emergency blade too.
