|---|---|---|---|
| Switchblade Key | Physical blade, basic RF | A4 (B5/B6), A6 (C5) | Moderate (Transponder based) |

| Smart Key (Standard) | Push-button start | A3, Q3, Q5 | High (Encrypted) |
| Advanced Key | Proximity/Keyless entry | A6, A7, A8, Q7, Q8 | Advanced (Rolling codes) |
| Audi Digital Key | Mobile phone combination | Late 2021+ Models | Bio-metric/NFC |
Key Features and Hidden Functionalities

| Aspect | Car dealership | Independent Locksmith |
|---|---|---|
| Expense | High (₤ 400 - ₤ 700+) | Moderate (₤ 250 - ₤ 500) |
| Equipment | Factory ODIS Software | Specialized Diagnostic Tools |
| Convenience | May require towing to dealership | Frequently mobile/comes to you |
| Security | Confirmed Audi link | Differs by locksmith track record |
Why is it so Expensive?

To configure a new key, the technician needs to get to the Immobilizer (IMMO) system, which includes cleaning old secrets and syncing the new rolling code file encryption.
Security Concerns: Protecting against "Relay Attacks"
