Keyless suddenly out of function

Hi together, since Thursday evening the keyless system no longer works with my Velar P400e (MY22). My wife returned from a business trip without any problems in the early evening. Later in the evening the Velar didn’t want to open the door handle with my key, I didn’t think about it and opened it with the button on the radio key. On Friday noon I wanted to start the car after the same problem, but only one hint was shown. The key can be positioned somewhere near the steering wheel and then press the start again. On the graphic in the info display you could not really see the exact position, but in the iGuide you would see clearly (under the steering column in the middle in a recess). Then the car also jumped on. But since then it no longer likes to recognize both keys via Keyless. I always have to open the door manually via the remote control and perform this start procedure. the same: foot kick and button on the boot cover do not react to opening, only to closure, even here only the button in the interior or on the radio key helps. Unfortunately there is the appointment with the dealer only at the beginning of November. Maybe someone has had a advice or already had the problem by then? VG Martin
