The Programming Process

Developing an Audi extra key is a two-step process: physical cutting and digital synchronization.

Physical Cutting

For designs with a physical blade (even the concealed "emergency situation" blade inside a wise fob), a laser cutter is required. Audi utilizes "sidewinder" or "internal cut" secrets, which are much more difficult to duplicate than standard home secrets or older car keys.

Software Synchronization

The key should be "introduced" to the vehicle's Immobilizer (IMMO) system. This includes:

• Connecting a computer system to the On-Board Diagnostic (OBD-II) port.
• Accessing the car's security pin code.
• Syncing the rolling codes of the remote to the Central Convenience Module.
• In newer designs (Immobilizer V and VI), this process requires a secure live connection to Audi's servers.

• Keep the Emergency Blade: If the electronic fob stops working, there is constantly a mechanical lock (typically hidden under a plastic cap on the motorist's door deal with) and a mechanical blade inside the fob to get inside the car.
• Prevent Moisture: The circuit boards inside Audi fobs are sensitive. If a key gets wet, get rid of the battery instantly and dry it with silica gel.
