Start, warm, defrost, or cool your 2008–2010 Infiniti QX56 from home or the office using your existing factory key fob. This OEM-style kit includes an HCX data module, plug-in T-Harness, and all installation hardware, with firmware preloaded for your vehicle. Designed for vehicles with Intelli-Key and automatic transmission, it uses your factory remote to start the vehicle by pressing the lock button three times—no extra remotes needed. Semi plug-and-play installation reduces wiring connections, though some wiring is still required—concise instructions with wire colors and locations are provided. Includes U.S.-based technical support and a downloadable MPC installation tip sheet. Does not work in vehicles without a factory immobilizer system or in some vehicles manufactured for sale outside the U.S. and Canada.
