I can unlock the driver door manually with the physical key but I have to put the key in the ignition within 10 seconds or the alarm goes off.
That is normal if you don't / can't use the keyfob to open the doors.

You have to turn the key in the doorlock to the right for approx. 10 secs and hold it there. Than turn the key left and the central locking system will open the car. Also the alarm system is deactivated.

You can try to resync the keys to get the original keyfobs to work again.
