Audi A6 dashboard displays a key symbol under the following circumstances: Low battery in the remote key: This prompt will appear on the dashboard. If you're unsure whether the car's remote key is functioning properly, try replacing the remote key battery with a new one first. The yellow key warning light is likely the engine immobilizer system alert. It's advisable to check if the smart key battery is depleted.

For new cars, you can visit an authorized dealership for assistance or use their diagnostic computer for testing.

If the issue persists, it's recommended to visit a professional repair shop to identify the specific cause.
I've been driving an Audi A6 for several years, and the key icon appearing on the dashboard is quite common. It usually means the car isn't detecting the signal from the key. This could be because the key battery is running low, causing a weak signal that triggers the anti-theft system alarm; or the key is too far from the car, and the in-car receiver can't sense it; sometimes, interference from mobile phones or other electronic devices can also cause this. This warning should be addressed promptly because if the battery dies completely, the car might not start or could lock the doors. It's recommended to first try replacing the battery—the key typically uses a CR2032 battery, which is cheap and easy to find. Also, try keeping the key close to the steering wheel or center console when operating it. If the issue persists, it might be necessary to check the key system module for faults or whether a software update is needed. Remember to have the technician check the key during regular maintenance to avoid small problems turning into bigger issues.
