About TT Keys
Verified key reference for the Audi TT — 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 |
|---|---|---|---|---|
| TT | 2000–2006 | Transponder | Megamos Crypto ID48 | HU66 |
| TT | 2006–2013 | Flip remote | Megamos Crypto ID48 (precoded) | HU66 |
| TT · TTS (8S) | 2014–2018 | Smart key | Megamos Crypto AES | HU162T |
Security System & Immobilizer
Audi spans Megamos ID48, the 8E era, Hitag-extended precoded keys, and Megamos AES on MLB/MQB platforms.
On the TT specifically we see: Megamos Crypto ID48, Megamos Crypto ID48 (precoded), Megamos Crypto AES. A correctly cut but unprogrammed key turns the locks and never starts the engine — programming is the half of the job that matters.

Audi TT Key FAQ
I lost the only key to my TT. 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.
My TT is push-to-start — can you program that outside the dealer?
Yes. Late models (2014–2018) use a proximity smart key on Megamos Crypto AES — we carry the fobs and the programmer, and we cut the emergency blade.
Do you still stock keys for older TTs?
Yes — back to the 2000–2006 generation (transponder), and a fresh code-cut key beats any copy of a worn original.
