This plug-and-play remote start kit is designed specifically for the 2005-2008 Infiniti FX35 with a key start ignition and automatic transmission, letting you start your vehicle by pressing the lock button three times on your factory key fob. Because it works with your existing OEM fob, the range matches what you already have, and the vehicle stays running when you open the door so you can get in and go without restarting. The kit includes everything needed for installation, requires no dealer activation or Stage 2 programming, and connects with a simple one-wire hookup. It is also compatible with optional add-on long-range remotes and an app module for expanded control.
