Connecting a computer system to the On-Board Diagnostic (OBD-II) port.Accessing the vehicle's security pin code.Syncing the rolling codes of the remote to the Central Convenience Module.In newer designs (Immobilizer V and VI), this procedure requires a protected live connection to Audi's servers.Cost Comparison: What to Expect

Maintenance and Troubleshooting

While the costs connected with these keys can be higher than those for standard vehicles, the security advantages offered by Audi's encrypted immobilizer systems are well worth the financial investment.
