About Diamante Keys
Verified key reference for the Mitsubishi Diamante — 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 | Blade / FCC |
|---|---|---|---|---|
| Diamante | 1997–2002 | Transponder key | Texas 4C / ID4C; later Texas 4D · 4D60 | MIT8 (MIT1) |
| Diamante | 2002–2005 | Transponder key | Texas Crypto 4D · 4D61 | MIT8 (MIT1) |
Security System & Immobilizer
Mitsubishi ran 4D61 transponders before ID46 chips and the FAST-Key proximity system.
On the Diamante specifically we see: Texas 4C / ID4C; later Texas 4D · 4D60, Texas Crypto 4D · 4D61. A correctly cut but unprogrammed key turns the locks and never starts the engine — programming is the half of the job that matters.

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