Scenic II automatic door locking antenna location

Hi,

My scenic II should have automatic door locking when I walk away or press the butten on door handle. It's not working properly. Only passanger side button works.

There should be antenna for this option, where is it located? I read that there have been some problemis with antenna, but I could not find the location of it.

Thanks in advance.
