Car not responding to my remote

Question

I have a 2016 Hyundai Elantra 2016 automatic with the Fortin FTX75 kit installed. I bought this car used so I didn’t install the kit myself. Everything was working fine two days ago and now when I try any commands (unlock, lock, start, trunk, etc..) the remote works ( light turns on) but it looks like the car isn’t receiving the signal. I don’t know why this happened.

Answer 1

Could be a defective remote, the light turning on does not mean the remote is transmitting.

Also check in the vehicle windshield there is a black antenna, it can come disconnected by someone washing the interior windshield.
