About S6 Keys
Verified key reference for the Audi S6 — 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 |
|---|---|---|---|---|
| A6 · S6 | 1997–2004 | Transponder | Megamos Crypto ID48 | HU66 |
| A6 · S6 (C6 4F) | 2004–2010 | Flip remote | Sokymat Crypto 8E (ID8E) | HU66 |
Security System & Immobilizer
Audi spans Megamos ID48, the 8E era, Hitag-extended precoded keys, and Megamos AES on MLB/MQB platforms.
On the S6 specifically we see: Megamos Crypto ID48, Sokymat Crypto 8E (ID8E). A correctly cut but unprogrammed key turns the locks and never starts the engine — programming is the half of the job that matters.

Audi S6 Key FAQ
I lost the only key to my S6. 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 S6?
On transponder-era cars it opens doors and nothing else — the chip must be programmed to the immobilizer, which is what we do curbside.
