Stage 3: Transponder Programming
This is the most important action. A blank secret may turn the ignition, but the car will not begin without the right electronic signature. A service technician connects a diagnostic tool to the automobile's OBD-II port to "handshake" the brand-new key with the Immobilizer Control Unit.
4. Why Professional Services are Required
