I have a viper 791xv installed in my car. I have a question for anyone that can help me. the remote start works fine, its just that sometimes when i don't want to start my car with the remote and i try to just start it with the key, it won't start. it will crank and crank but it won't start. and at that point i just start it with the remote and it works fine, can anyone tell me why this happens
