How many times does the Audi A6 key light flash when pressed once?

[LaNolan]

The Audi A6 key light flashes once when pressed. If it flashes slowly three times, it indicates that the key is out of the sensing range and the car is already locked. If it flashes quickly three times, it means the vehicle is not locked properly. Hidden functions of the Audi A6 key: Press and hold the unlock button, and all four windows will roll down together; press and hold the lock button, and all four windows will roll up together. However, this function is not enabled by default and needs to be set in the multimedia system under driving assistance before it can be used. Reasons why the car key does not start: A common reason is insufficient battery power in the car key, in which case the battery needs to be replaced. If there is no response when pressing the key near an airport or radio transmitter, try moving the vehicle away from these areas and try again, as it is likely due to signal interference affecting the car key's control. Additionally, if there is no reaction when inserting the key to start, it is best to check the starter relay, starter fuse, and other components before trying again.
