Remote range issue not the battery



So the problem is we seem to have arranged issue where the remote will not work unless I walk up to the where the vent tag is or the side of the door. I’m thinking antenna issue.
Now this does happen on the two original remotes so it’s not a remote issue or a battery issue.
There must be an antenna box or something to that effect that the range has been affected
Now the antenna on the top by the rear windshield it’s black on my 06 cracked on my son was shoveling snow off of it. My understanding is that’s for satellite only. Can anyone confirm where the antenna is or where the signal gets picked up on a 209
If coupe then the roof antenna is GPS/Sirrus antenna.
The central locking antenna amplifier is stuck to the rear screen, so I guess the elements are in the screen....



I also noticed that my AM radio hits all the stations so I’m not sure if it’s the boost or after all this is a weird one because the remote was working perfectly fine today
