okay, I'll bite... There are a few issues with the remote starts... 1) If not done correctly, your vehicle can start on it's own without you pressing a button, which, if your vehicle is in a garage under your house, can pose a lethal risk - most people are not willing to accept that responsibility. 2) If not done correctly your vehicle can shut off while you are driving (someone had that happen on a professionally installed system). - nice to have the reassurance that the company who installed it will pay for the towing and all subsequent repairs to make the system work. 3) Having a key nicely located inside the vehicle will make it easier for someone to illegally borrow your vehicle, especially if the timers are not setup to shut off the vehicle automatically. 4) Any modification may void the factory warranty in the areas you were making changes. It's nice to have a nother company assume responsbility for those modifications.
Sometimes, installing the systems and fighting the factory installed security/electronics is more time consuming than just taking it to someone to have them do it. Mostly, it's a matter of choice. If you feel comfortable with all of the risks, go for it.
