Here is my take on aftermarket alarms, and starters. A few important factory wires get cut, and then power, or signals are re- routed through cheap chineese relays, or alarm modules. 10 years down the road, when you start to have weird starting, or no starting problems, tracking it down is always fun, usually requiring complete replacement of the unit, because there are no serviceable parts, and the model is usually not in production any more . I would do a factory remote start if possible.
I am sure most of them are trouble free, but I have fixed quite a few pia electrical problems in my day due to this stuff. I walk out in the morning, and start the cars for her and I.
