Kleinn Remote Start System

Complete Remote Starter Kit: This kit includes an all-in-one data module and wiring harnesses, with firmware preloaded specifically for your vehicle. All components necessary for installation are included. For automatic transmission vehicles only.

This kit features a genuine Plug & Play design. The wiring Harness is engineered to eliminate the complex wiring connections eliminating the need for a professional installer. Installation involves removing the light paneling like the steering column cover to access the connection points, but the connections themselves are simple and easy plug-ins.

Start your car using your existing remotes by simply pressing the "lock" button three times—no need to carry extra key fobs! Enjoy the convenience of warming up or cooling down your vehicle from the comfort of your home. When you're ready to drive, just insert your key into the ignition and go! Please note that this system does not include remotes; it utilizes your factory remotes. Extended Range and additional remotes are linked in the description bellow.
