Xceed does not lock and makes permanent pageant

Hello. I have found nothing suitable about the search function… We have our Xceed since yesterday. However, 3 drivers have the same problem while parking and then locking. Car is switched off in “P”, with start/stop off and exit the car. A normal car would lock either with a button at the door handle or with “key” from a certain distance. Instead, the car beeps in the continuous tone so about 5-6 seconds. Only after restarting the car you can use The second key is not inside the car. What do you have to do to complete the car? Lg
