Security System & Immobilizer

Audi spans Megamos ID48, the 8E era, Hitag-extended precoded keys, and Megamos AES on MLB/MQB platforms.

On the A7 specifically we see: Hitag-Extended VAG (PCF7945AC). A correctly cut but unprogrammed key turns the locks and never starts the engine — programming is the half of the job that matters.

Audi A7 Key FAQ

I lost the only key to my A7. 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 A7 is push-to-start — can you program that outside the dealer?

Yes. Late models (2011–2018) use a proximity smart key on Hitag-Extended VAG (PCF7945AC) — we carry the fobs and the programmer, and we cut the emergency blade.
