About Milan Keys
Verified key reference for the Mercury Milan — 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 |
|---|---|---|---|---|
| Milan | 2006–2009 | Transponder (PATS) | Texas Crypto 4D63 (80-bit) | H92 / H84 (shares Fusion) |
| Milan | 2010–2011 | Transponder (PATS) — IA optional, confirm by VIN | Texas Crypto 4D63 DST80 (80-bit) | H75 (shares Fusion) |
Security System & Immobilizer
Mercury vehicles run Ford’s SecuriLock/PATS immobilizer of their era — 4D63 transponders and remote-head keys — still fully serviceable despite the brand’s retirement.
On the Milan specifically we see: Texas Crypto 4D63 (80-bit), Texas Crypto 4D63 DST80 (80-bit). A correctly cut but unprogrammed key turns the locks and never starts the engine — programming is the half of the job that matters.
Which key does your year have?
- 2006–2009: Transponder (PATS) — Texas Crypto 4D63 (80-bit) (H92 / H84 (shares Fusion))

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