This plug-and-play remote start kit is designed specifically for the 2005-2008 Infiniti FX45 equipped with an Intelligent Key "knob" ignition and automatic transmission, providing a true no-cut, no-splice installation that requires no dealer activation. It starts and stops the engine by pressing the lock button three times on your factory key fob, and because it uses the OEM fob, operating range matches your original key. Once started, the vehicle runs for 15 minutes and stays running when you open the door, so you can get in and drive without restarting. The kit is complete with all necessary components, includes one optional wire connection for parking light illumination, and is compatible with add-on long-range remotes and app modules.
