# Kleinn 03-06 (2007 Classic Only) CHEVY/GMC Full Size Trucks & SUVs - Remote Start 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. - Notes: Pre-Flashed (Programmer Included), 15 Minute Runtime, 55 Minute Install , Semi-Plug & Play (1 Wire Connection) - Parts Included: Firstech HCX Remote Start / Data Module, ADS-THR-GM12 T-harness - Remotes: Two (2) 4-Button Remotes (Up to 3,000ft Range) - Transmission: Automatic Only - Ignition Type: Key-to-Start - Fuel Type: Gas or Diesel This Part Fits: Year Make Model Submodel 2003-2006 Cadillac Escalade Base 2003-2006 Cadillac Escalade EXT Base 2003-2005 Chevrolet Avalanche 1500 Base 2005-2006 Chevrolet Avalanche 1500 LS 2005-2006 Chevrolet Avalanche 1500 LT 2003 Chevrolet Avalanche 1500 North Face 2003 Chevrolet Avalanche 1500 On Road Edition 2003 Chevrolet Avalanche 1500 WBH 2004-2006 Chevrolet Avalanche 1500 Z66 2003-2006 Chevrolet Avalanche 1500 Z71 2003-2007 Chevrolet Express 2500 Base 2003-2007 Chevrolet Express 2500 LS 2006-2007 Chevrolet Express 2500 LT 2003-2005 Chevrolet Silverado 1500 Base 2004-2006 Chevrolet Silverado 1500 Hybrid 2003-2006 Chevrolet Silverado 1500 LS 2003-2006 Chevrolet Silverado 1500 LT 2003-2006 Chevrolet Silverado 1500 SS 2003-2006 Chevrolet Silverado 1500 WT 2004-2005 Chevrolet Silverado 1500 Z71 Off-Road 2007 Chevrolet Silverado 1500 Classic Hybrid 2007 Chevrolet Silverado 1500 Classic LS 2007 Chevrolet Silverado 1500 Classic LT 2007 Chevrolet Silverado 1500 Classic SS 2007 Chevrolet Silverado 1500 Classic WT 2003-2004 Chevrolet Silverado 2500 Base 2003-2004 Chevrolet Silverado 2500 LS 2003-2004 Chevrolet Silverado 2500 LT 2004 Chevrolet Silverado 2500 WT 2007 Chevrolet Silverado 2500 HD Classic LS 2007 Chevrolet Silverado 2500 HD Classic LT 2007 Chevrolet Silverado 2500 HD Classic WT 2003-2005 Chevrolet Silverado 3500 Base 2003-2006 Chevrolet Silverado 3500 LS 2003-2006 Chevrolet Silverado 3500 LT 2004,2006 Chevrolet Silverado 3500 WT 2007 Chevrolet Silverado 3500 Classic LS 2007 Chevrolet Silverado 3500 Classic LT 2007 Chevrolet Silverado 3500 Classic WT 2006 Chevrolet Suburban 1500 Base 2003-2006 Chevrolet Suburban 1500 LS 2003-2006 Chevrolet Suburban 1500 LT 2006 Chevrolet Suburban 1500 LTZ 2003-2006 Chevrolet Suburban 1500 Z71 2006 Chevrolet Tahoe Base 2003-2006 Chevrolet Tahoe LS 2003-2006 Chevrolet Tahoe LT 2003-2006 Chevrolet Tahoe Z71 2003-2007 GMC Savana 1500 Base 2006-2007 GMC Savana 1500 LS 2006-2007 GMC Savana 1500 LT 2003-2005 GMC Savana 1500 SLE 2003-2007 GMC Savana 2500 Base 2007 GMC Savana 2500 LS 2007 GMC Savana 2500 LT 2003-2005 GMC Savana 2500 SLE 2003-2007 GMC Savana 3500 Base 2006-2007 GMC Savana 3500 LS 2006-2007 GMC Savana 3500 LT 2003-2005 GMC Savana 3500 SLE 2003-2005 GMC Sierra 1500 Base 2003-2006 GMC Sierra 1500 Denali 2005-2006 GMC Sierra 1500 Hybrid 2003,2006 GMC Sierra 1500 SL 2003-2006 GMC Sierra 1500 SLE 2003-2006 GMC Sierra 1500 SLT 2003-2006 GMC Sierra 1500 WT 2007 GMC Sierra 1500 Classic Denali 2007 GMC Sierra 1500 Classic Hybrid 2007 GMC Sierra 1500 Classic SL 2007 GMC Sierra 1500 Classic SLE 2007 GMC Sierra 1500 Classic SLT 2007 GMC Sierra 1500 Classic WT 2003-2004 GMC Sierra 2500 Base 2003-2004 GMC Sierra 2500 SLE 2003-2004 GMC Sierra 2500 SLT 2003-2004 GMC Sierra 2500 WT 2003-2005 GMC Sierra 3500 Base 2006 GMC Sierra 3500 SL 2003-2006 GMC Sierra 3500 SLE 2003-2006 GMC Sierra 3500 SLT 2004-2006 GMC Sierra 3500 WT 2007 GMC Sierra 3500 Classic SL 2007 GMC Sierra 3500 Classic SLE 2007 GMC Sierra 3500 Classic SLT 2007 GMC Sierra 3500 Classic WT 2003-2006 GMC Yukon Denali 2006 GMC Yukon SL 2003-2006 GMC Yukon SLE 2003-2006 GMC Yukon SLT ## Details - **Price:** 450.52 CAD - **Vendor:** Kleinn Air Horns - **Type:** Switch Panels ## Variants | Variant | Price | Available | |---------|-------|-----------| | Default Title | 450.52 CAD | In stock | --- > Source: [Standard Auto Part](https://www.standardautopart.com/products/kleinn-03-06-2007-classic-only-chevy-gmc-full-size-trucks-suvs-remote-start) > Updated: 2026-06-29
