Hey there guys, I have an issue with my 2003 vrs

 

1. when I lock the car via remote I have to be very close to the car for it to work, I have a 1.9tdi octy that had the same central lock and the distance required was much shorter, what could be the issue???where is the receiver antenna ? 

 

2. the rear right door just stopped locking, everything was fine but all of a sudden it stopped, what could be the reason ?, i doubt that the two issues are interlinked as the central lock distance was short to begin with. 

 

Thanks ! 

Have tried replacing the battery in the key fob?

Does the window work on the rear door?

first thing i did was replace the battery, however did not help, and the window does work, i took off the panel and there is a weak whine from the servo
