The Kleinn lineup we stock is built around push-to-start Toyota and Lexus vehicles, and it splits cleanly into base kits and upgrades. The base kits are vehicle-specific modules that add remote start on their own. The upgrades extend a starter you already have, so they are not a substitute for a base kit.
Three base kits cover the range. The RSTOY6 fits the 2016-2019 Tacoma and Highlander plus select 2016-2022 Toyota push-to-start models. The RSTOY6A fits the 2013-2018 RAV4 plus select 2012-2019 Toyota push-to-start models. The RSTOY13 covers select 2018-2025 Toyota and Lexus cars and SUVs in both gas and hybrid. All three are listed as requiring no programmer, which is the practical advantage of a vehicle-specific kit over a universal one.
The upgrades solve two different problems. The RFKIT antenna kits extend fob range and come three ways: the RFKIT1 with two 1-button one-way remotes, the RFKIT4 with two 4-button one-way remotes, and the RFKIT2W with two 4-button two-way remotes that confirm back when the vehicle actually starts. The MOBILE2W skips the fob entirely, adding smartphone app control and GPS tracking.
