Kleinn RSFD21 Plug-and-Play Remote Start System for 2021-2023 Ford F-150
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2021-2023 Ford F-150 models (Gas, Hybrid, and Diesel) with automatic transmissions.
The Kleinn RSFD21 is a vehicle-specific remote start system designed for a seamless, 100 percent plug-and-play installation on 2021-2023 Ford F-150 trucks. Built around the FORT21 T-harness, this module bridges directly into the factory wiring harness, eliminating the need for cutting or splicing. This approach preserves the integrity of your truck's electrical system while allowing for a straightforward installation that can typically be completed in about 20 minutes using basic hand tools.
The module arrives pre-flashed for the F-150 platform, supporting both traditional key-to-start and modern push-to-start ignitions without requiring an external programmer. Once installed, the system is triggered using your factory keyless entry remote via a Lock-Unlock-Lock sequence. It provides a 15-minute engine runtime to pre-condition the cabin, and remains fully compatible with optional long-range kits or smartphone-controlled modules.
