Why can't the Audi Q3 recognize the key?

[LeAddyson]

Here are the specific reasons why the Audi Q3 cannot recognize the key: Audi Q3 key battery depletion: If the Audi Q3 remote key is low on battery or the battery is weak, the car's signal receiver may fail to detect the remote signal, causing the dashboard to display a "key not recognized" message. Simply replace the remote battery with a new one. Note: It is recommended to use an original Audi battery, as using a generic battery may result in the same issue recurring. Signal interference: If there are signals in the vicinity of the vehicle that operate on the same frequency as the Audi Q3 remote key, it may cause the dashboard to display a "key not found or recognized" message. Devices with the same frequency as the remote key signal include large LED signs, mobile signal towers, etc. In such cases, place the Audi Q3 remote key in the induction area (located under the wiper, marked with a visible key and wireless signal symbol), then press the brake and start the vehicle.
