Creating an Audi spare key is a two-step process: physical cutting and digital synchronization.
Physical Cutting

Software application Synchronization
The key needs to be "presented" to the car's Immobilizer (IMMO) system. This involves:
Connecting a computer system to the On-Board Diagnostic (OBD-II) port.Accessing the automobile's security pin code.Syncing the rolling codes of the remote to the Central Convenience Module.In more recent designs (Immobilizer V and VI), this procedure needs a protected live connection to Audi's servers.Cost Comparison: What to Expect

If a key gets damp, get rid of the battery right away and dry it with silica gel.Regularly Asked Questions (FAQ)Can I program a new Audi key myself?

What should I do if I lose all my secrets?
If all secrets are lost, the process becomes "All Keys Lost" (AKL). This is substantially more pricey due to the fact that the locksmith or dealer must "reset" the immobilizer system rather than simply replicating an existing code.

An Audi extra key is an advanced piece of innovation that acts as the bridge between the chauffeur and their high-performance machine.
