Need to study YouTube videos on how to get behind the lower dash covers. Once you figure out how to access the correct ports, process is easy. Working great1

Installed on my wife's 2017 Lexus RX350 today. Connecting the harness took a while only because behind the dashboard is really tight. I had to use many needle-nose pliers for the connectors, my hands did not fit. Everything else worked perfectly. Programming was flawless. Climate controls work with remote start. Car shuts off when door is opened. FOLLOW INSTRUCTIONS EXACTLY and you'll be fine. I'll update if anything changes (12/28/2024).

Installed in 2017 Rx350 worked fine for a week . Then the car just didn't start anymore, had to have it towed to the stealership and they determined the ecu needed to be replaced. BEWARE of potential problems with lexus aftermarket remote starts

Super easy to install and program.. works like a charm.. MUST READ INSTRUCTIONS BEFORE DOING ANYTHING. WATCH YOUTUBE VIDEOS FIRST FOR HOW TO REMOVE DASH COVERS. if I buy any other Lexus, I will look for external products like this one with app start instead of paying subscription to Lexus. This one is remote start. Lexus doesn’t support 3G rework anymore nor they can upgrade it to current 5g network.

WIth my original purchase I had issues with the Tire Pressure Sensors no longer working correclty after installing the remote start module. I had to contact MPC who eventually shipped a second wiring harness. The second wiring harness resolved the issue and now everthing is working properly. I am giving them a three star rating becuase of poor quality controls. (I am not the first person writing a reivew mentioning the issues with the Tire Pressure Sensors not working). As an installation tip: Do not button up your panels until test driving your car. The Tire Pressure Sensors will not potenially fail until you start driving the car. If you car drives around a couple miles you should be good to go and then can button up your panels.

Must be standing right next to driver door for it to start (defeating the purpose) and it actually only works 10% of the time. Once installed my automatic brights stopped working and my automatic headlight setting does not work anymore
