im looking for a new alarm for my car it has the stock alarm if that means anything to you. but i live in the desert i and i was hoping for the remote start and i was wondering are there any big challenges in my way or is it just buy an alarm and install. and also ive seen cheap ones and expensive ones and i was wondering is there something that the cheap ones are missing other than quality of course or is there like a module or program or something thats specially needed for starting the car, or do i just buy one that says remote start and im good ??? thankyou all for any info
