If the code matches the one saved in the car's memory, the immobilizer allows the engine to begin.
Development of the Immobilizer
Audi has actually phased through numerous generations of immobilizer innovation, typically referred to as Immo 1 through Immo 5, and the newest MQB platforms.
Immo 1 to 3: Found in older models (late 90s to mid-2000s). These are normally easier for locksmith professionals to program.Immo 4 and 5: Introduced in the late 2000s.

Action 2: Accessing the OBD-II Port
The service technician links a diagnostic tool to the lorry's On-Board Diagnostics (OBD-II) port, situated under the chauffeur's side control panel. This enables the software to interact with the Immobilizer Control Module and the Body Control Module (BCM).
Action 3: Clearing Old Keys
For security functions, it is basic practice to wipe all formerly set keys from the vehicle's memory. This guarantees that if a key was stolen, it can no longer be used to start the car.
