Understanding Remote Start Features
The 2021 Jeep Grand Cherokee comes with a built-in remote start system on most trims. This lets you start the engine from outside your vehicle, usually up to 300 feet away. It’s useful for climate control, security, and convenience. You can use the key fob or the Uconnect app (on some models).
Key Fob Remote Start
Most Grand Cherokees have a key fob with a circular arrow button, which is the remote start button. You can use this for a quick start.
Uconnect App Remote Start
If your Jeep is equipped with Uconnect services, you can use your smartphone to start the engine from anywhere with an internet connection.

Using The Key Fob

- Within five seconds, press the remote start button twice (the circular arrow). The engine should start, and the lights will flash.
- Your Jeep will run for 15 minutes. Press the remote start button again to extend for another 15 minutes.
