Today had installed security alarm (grande replica one) in my car, now since it has been installed, it is going off automatically every after 20-30 minutes.. I took the car back to shop and shop wala replaced the unit, this replacement unit is showing the same problem.. Car is pretty new got it 3 days back so dont think door switch panels are at fault here. Im guessing electrician messed up wiring.. Any one can suggest anything.?. I will surely take the car back to shop shortly .. Car has tracker installed and it is gli 2015
