Alarm Kit

This product was purchased out of necessity due to someone attempting to steal my car. I own a Kia Soul. The self starter and alarm system are a Godsend to me and my family because without my car, I am unable to work. I am thankful for Best Buy and the team who installed the equipment, I highly recommend them for all of my electronic related needs and customer service!

No instructions

Do your research! This is a great product, unfortunately they don't offer details installation instructions like other brands.
Compustar is a professional installation brand not designed for DIY.
If you buy this you'll also need the programmer to adjust settings or have to go to an installer for these adjustments.
I spent twice as long figuring out how to wire this unit into my truck as I did actually installing it. Luckily I found a good forum with an article from a guy who documented the wiring.
Would have given it 5 stars if they had instructions.

You have to have a professional installer flash it buyers beware

I couldn't install it because it has to be flashed by a professional installer who could possibly charge you up to $300 just to flash it. I can't speak for the actual system because I returned it

My car is safe now

Because all old Honda keys can be used on all other old Hondas, I worried that someone could easily steal my car. Now I don't worry.
