About 6 Keys
Verified key reference for the Mazda 6 — model years, key types, and the transponder/immobilizer each generation uses. Boundary years can overlap; we confirm the exact part by VIN before dispatching.

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 6 specifically we see: Texas 4D63 (early), 80-bit ID63 (2008+), TP20, TPX2 / XT27 / K-JMD, Tiris DST+ (DST80), Texas 4D63 80-bit (ID63), GHY5675DY, GJY9675DY. A correctly cut but unprogrammed key turns the locks and never starts the engine — programming is the half of the job that matters.

Mazda 6 Key FAQ
I lost the only key to my 6. 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 6?
On transponder-era cars it opens doors and nothing else — the chip must be programmed to the immobilizer, which is what we do curbside.
Do you still stock keys for older 6s?
Yes — back to the 2003–2008 generation (transponder / remote-head), and a fresh code-cut key beats any copy of a worn original.
How fast can you reach my 6 in DFW?
