Contemporary Comparison of Audi Key Types
| Key Generation | Main Feature | Era/Models | Security Level |
|---|---|---|---|
| Switchblade Key | Physical blade, fundamental RF | A4 (B5/B6), A6 (C5) | Moderate (Transponder based) |

| Convenience | May need towing to dealership | Frequently mobile/comes to you |
| Security | Validated Audi link | Differs by locksmith track record |
Why is it so Expensive?

- Signal Interference: Large metal objects, cell phones, or radio towers can interfere with the fob's signal.
- De-synchronization: Occasionally, if the battery is dead for a long period, the fob may lose its sync with the car. This typically needs a professional reset.
