About B4000 Keys
Verified key reference for the Mazda B4000 — 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 |
|---|---|---|---|
| B4000 | 1999-2001 | Temic Crypto 8C or Texas 4C | TK5561 / TP17 or TP02 |
| B4000 | 2001-2006 | Temic Crypto 8C or Texas 4D ID63 | TK5561 / TP17 or TP20 |
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 B4000 specifically we see: TK5561 / TP17 or TP02, TK5561 / TP17 or TP20. A correctly cut but unprogrammed key turns the locks and never starts the engine — programming is the half of the job that matters.

Mazda B4000 Key FAQ
I lost the only key to my B4000. 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 B4000?
On transponder-era cars it opens doors and nothing else — the chip must be programmed to the immobilizer, which is what we do curbside.
