Want to warm up or cool down your Cadillac ATS before you even step outside? This MPC remote start kit lets you do just that—using your existing factory key fob! Compatible with 2013-2019 Cadillac ATS push-to-start models (automatic transmission, gas only), the system is activated by pressing the 'lock' button three times. No extra fobs to carry! The kit includes an all-in-one data interface module, a T-harness for semi plug-and-play installation (only one wire connection required), and a Fortin Flash Link Updater for easy PC setup. We provide detailed instructions and U.S.-based tech support Monday-Friday to help with installation. Please note: a Windows PC with a USB port is needed for initial configuration, and the system is designed for U.S./Canada vehicles only. Optional smartphone control and additional remotes are available separately. Enjoy the convenience of remote starting from the comfort of your home or office!
