"The Fortin TOY9-ONE is the heavy-duty, all-in-one remote start and security solution specifically for Standard-Key (Turn-Key) ignition Toyota vehicles that utilize a High-Current ignition switch. At Lockdown Security, we designate the TOY9-ONE as the essential kit for the 2010–2021 Toyota 4Runner and the 2011–2020 Toyota Sienna, because the included THARONE-TOY9 T-harness is engineered to handle the 12V power distribution and immobilizer data for both G-Key (80-bit) and H-Key (128-bit) systems. While it allows for '3x Lock' starting on most models, it is important to note that certain G-Key 4Runners and Siennas may require an additional RF remote kit or smartphone controller for activation. This is a strictly high-current, keyed-ignition kit and is not compatible with Push-to-Start models. For the 4Runner enthusiast or Sienna family, this provides a robust, professional-grade installation that respects the vehicle's heavy-duty electrical architecture."
