    Upgrade your 2003 to 2006, as well as 2007 Classic model, Chevrolet and GMC full-size trucks and sport utility vehicles with a Kleinn wireless remote start system. This premium upgrade allows you to easily cool down your vehicle in the summer and warm it up in the winter before you ever step inside the cab. Engineered specifically for gas or diesel engines equipped with automatic transmissions, this system features a traditional key-to-start ignition compatibility. The comprehensive kit includes a premium Firstech HCX remote start and data module paired with a vehicle-specific T-harness for a convenient semi-plug-and-play installation that requires only a single wire-to-wire connection to the factory brake wire. Because the module comes pre-flashed straight out of the box, setup is fast and simple, providing a dependable 15-minute runtime. This package comes complete with two long-range four-button remote controls that allow you to start your vehicle from up to three thousand feet away. For drivers looking to expand their setup even further, this system is fully compatible with smartphone control upgrades including the Drone smartphone module or the mobile two-way smartphone upgrade kit.
