The Programming Process

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

Physical Cutting

For designs with a physical blade (even the hidden "emergency situation" blade inside a clever fob), a laser cutter is required. Audi uses "sidewinder" or "internal cut" keys, which are much more difficult to replicate than basic home secrets or older car secrets.

Software application Synchronization

The key needs to be "presented" to the automobile's Immobilizer (IMMO) system. This includes:

• Connecting a computer system to the On-Board Diagnostic (OBD-II) port.
• Accessing the lorry's security pin code.
