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.

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.

Which key does your year have?

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.

How fast can you reach my TT in DFW?

We dispatch the nearest mobile unit metroplex-wide, 24/7 — call (214) 717-6398 for an honest ETA.
