About Mulsanne Keys
Verified key reference for the Bentley Mulsanne — 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 |
|---|---|---|---|---|
| Mulsanne | 2011–2020 | Flip remote w/ keyless-go (315/433 MHz) | Hitag2 / ID46 (PCF7942) | HU66 |
Security System & Immobilizer
VW-era Bentleys follow Audi platform security of their generation — from ID46-era remotes to MLB smart keys on Bentayga — with programming paths shared with their VW Group siblings.
On the Mulsanne specifically we see: Hitag2 / ID46 (PCF7942). A correctly cut but unprogrammed key turns the locks and never starts the engine — programming is the half of the job that matters.

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