After market accessories can do some crazy stuff? When I was at Volvo we had an S40 that the remote would not unlock the doors unless you were close to it. I replaced the receiver and same thing. I swapped modules, swapped doors, did software and nothing.
I noticed the interior lights were replaced with LED lights so I removed them and the remote started unlocking the doors from far away. The LED lights were blocking the signal.
So yes, the after market lights could be causing the problem. Return the vehicle back to stock to see if the concern persist because any changes can potentially cause problems. You may have tapped into a wire that is interfering with the Can Bus and it is causing a disruption in the network. Everything in these new cars communicate with one another and it can cause a fault in the communication.
