I called up first thing in the morning, Kelley was very polite and knowledgeable about what I wanted. He told me to bring it in. In a few hours I had the best remote start and alarm on the market installed for less than the unit itself was posted on the viper website. AJ did a great job on the install of my 5902, very professional, no shortcuts here. I would reccommend to go here before you even consider anywhere else. They also have a huge display of anything you would want in stock, no waiting days for a product to come in. You would be wasting your time to look anywhere else first.
