right door handle won't sense key! please help
 

On my C70 2012 Volvo, it's got those RFID-enabled door handles which means if the original key is near the door handle, then, either pressing the button, or pulling the handle, should automatically unlock the doors in case they are locked. Also, if you intend to lock the doors, pressing the black door handle button with the KEY nearby should also allow the doors to react and lock.

After getting a paint job, I noticed that the right-door stopped reacting to this function. Only the trunk and the driver's door react correctly. Being from the technology side, I feel there is some RFID sensor that is either malfunctioning or missing for it NOT to sense that the KEY is within 30 cm outside the lock for it not to react.

Pressing the lock/unlock on the remote control makes all doors react correctly.

I checked in the Dash Panel, for the settings, and it is currently set to ALL DOORS.

Does anyone here have an idea how I can solve this problem?
