While many owners concentrate on the performance of the engine or the elegance of the Quattro all-wheel-drive system, among the most vital components of the vehicle is often ignored: the key. Audi key cutting is not an easy mechanical procedure; it is a mix of precision machining and complex electronic synchronization.

This design makes the lock cylinders much more difficult to choose and the secrets substantially more challenging to duplicate without specialized devices.
The Transponder Chip and Immobilizer
Given that the mid-1990s, Audi has actually integrated transponder chips into their secrets. When the key is inserted into the ignition or brought inside the cabin (for keyless start designs), the car's Immobilizer system sends an electronic signal to the key.

Once the key code is obtained, it is participated in a computer-controlled CNC (Computer Numerical Control) cutting machine. The machine uses a small, high-speed milling bit to sculpt the particular track into a blank Audi key blade. Because the tolerances are very tight-- typically measured in micrometers-- manual cutting is seldom effective for modern-day Audi keys.
3. Transponder Programming
After the blade is cut, it will turn the locks and the ignition, however the automobile will not start. The last step is programming. The specialist links a diagnostic tool to the automobile's OBD-II port to "marry" the brand-new audi car key transponder chip to the car's Engine Control Unit (ECU).
