Excellent Product
If you only want Remote Start using your existing Keyless Entry this item is perfect.
You will probably have to purchase 1 additional item to get around your particular vehicles Anti-Theft System, however both items are very reasonably priced. All it takes is a quick phone call to Sonic Electronix, and they will tell you exactly what you need. Even on Weekends!
Plan on having a professional install. There are a LOT of wires! You can purchase an "Install Card" from Sonic, and everything will be taken care of for you.
IT'S A NO BRAINER!!!
