      Description

      Remote Start System. The Kleinn Remote Start system provides convenient engine ignition from a distance, allowing you to warm up or cool down your vehicle before entry. It is designed specifically for select Chevy and GMC full-size trucks and SUVs, enhancing comfort and usability especially during extreme weather conditions.

      Construction and Appearance. This system includes a robust Firstech HCX remote start module paired with a custom ADS-THR-GM12 T-harness for seamless integration. The design ensures durable performance and a clean, factory-like installation that maintains the vehicle’s original aesthetics.

      Installation. Installation is semi-plug-and-play and requires only one wire-to-wire connection, minimizing complexity. No drilling is necessary, making this system suitable for DIY installation with basic technical knowledge.

      Warranty. This product includes a one-year limited defect warranty covering workmanship and material flaws under normal use.

      Application. Specifically designed for 2003-2006 (and 2007 Classic) Chevy/GMC full-size trucks and SUVs, this remote start system supports automatic transmissions only and is tailored to the operational protocols of these models.
