Since I own the car I think that something is wrong with my remote key controls ,because I have to stay very close to the drivers door and wave around my key fob to open and close my doors.I already tested my second key and replaced the battery in it but that doesnt help.Sometimes it works a little bit better and sometimes I need many tries to open/close my car what is very annoying.I often have the same problem with my trunk opener.
Is this a known problem.Do I have to replace something inside the car or is there a DIY to solve this.
The Search option didnt help me out with that one.

I have also found that u have to be very close to the car to get it to work... and im always losing my car in a parking lot. lol

aftermarket or factory remotes

I only have two factory remotes

sorry man, that I can't help with. hopefully someone else has an idea.
