Good day together I have a curious problem with my 2005 G55K. Last week as usual in the underground car park, button pressed at the key for unlocking… Alarm system starts…? At some point and somehow I got the alarm system to silence. Since then the opening and closing of the key does not work any more! Both keys try, batteries replaces…Nada. When I go off, the vehicle closes all doors as usual. When I press the button for the ZV on the dashboard it also works as on the first day. Did any of you ever have the problem before? There has to be a receiver for the signal, right? Where does it sit? I thought to ask you – before it goes to the friendly. Best thanks and greetings from Switzerland Benny
