Remote starting your Jeep Grand Cherokee is a convenient feature that can save time and add comfort, especially during extreme weather. Many owners use remote start to warm up the cabin in winter or cool it down in summer before driving. But not everyone knows how to use it correctly, or what options are available. In this article, you’ll learn the step-by-step process, find practical tips, and discover common mistakes to avoid. Whether your Grand Cherokee is new or a few years old, you’ll get clear guidance to make remote start work smoothly.
Understanding Remote Start In Jeep Grand Cherokee
Remote start lets you start your vehicle’s engine from a distance, using a key fob or a mobile app. The system is standard or optional on most Grand Cherokee models since 2014. It can turn on the engine, climate control, and sometimes heated seats, depending on trim and year.
Here’s a quick look at Grand Cherokee remote start compatibility:
| Model Year | Remote Start Standard | Remote Start Optional |
|---|---|---|
| 2014-2018 | Laredo, Limited, Overland | Some base trims |
| 2019-2024 | All except base Laredo | Base Laredo |
If your Grand Cherokee doesn’t have remote start, you can often add it through a dealer or aftermarket kits.
How To Remote Start Using Key Fob
Most Grand Cherokees with remote start use a key fob with a special button. The process is simple, but there are details you need to know.
- Check Vehicle Conditions
- Doors must be locked
- Hood must be closed
- Engine must be off
- Gear must be in park
- Press the Remote Start Button
- Locate the button with a circular arrow (often labeled “x2”)
- Press lock button once
- Immediately press and hold the remote start button for about 2 seconds
- The parking lights flash, and engine starts
- Climate controls turn on to last used settings
- Enter and Drive
- Unlock the car with the fob
- Enter and press the brake pedal
- Push the start button or insert the key (if required)
- Engine stays running, and you can drive as usual
Remote start usually runs for 15 minutes. You can extend it once by repeating the steps, up to a total of 30 minutes.
Common Remote Start Key Fob Issues
- Weak battery in the fob can cause failure
- Too far from vehicle (over 300 feet is risky)
- Not pressing buttons in correct sequence
- Vehicle not meeting required conditions
How To Remote Start Using Mobile App
Newer Grand Cherokees (2018 and newer) may support Uconnect app remote start. This method uses your smartphone, offering more flexibility.
- Register on Uconnect
- Download the Uconnect app
- Set up your account and link your vehicle
- Remote Start Steps
- Open the app
- Select your vehicle
- Tap the Remote Start button
- Wait for confirmation (usually a few seconds)
Mobile app remote start works anywhere with cell service, not just within fob range. It also lets you check vehicle status and lock/unlock doors.
App Vs Key Fob: Comparison
Here’s a quick comparison between remote start methods:
| Feature | Key Fob | Mobile App |
|---|---|---|
| Range | Up to 300 feet | Unlimited (cell network) |
| Status Alerts | No | Yes |
| Lock/Unlock | Yes | Yes |
| Subscription Required | No | Yes (after trial) |
Practical Tips For Effective Remote Start
- Pre-set climate controls before turning off the vehicle. The system uses last settings.
- Don’t leave valuables inside. Remote start doesn’t unlock doors.
- If using app, check for subscription expiration. Some features may stop working after the free period.
- For busy areas, avoid remote starting near crowds or garages with poor ventilation.
- Replace the key fob battery every 2 years for reliability.
Common Mistakes And How To Avoid Them
Many owners run into problems because of simple mistakes:
1. Trying To Start With Doors Unlocked
Remote start only works when doors are locked.
2. Remote Starting With Hood Open
Safety features prevent starting if hood is open.
3. Ignoring Security Alerts
If you get an alert on Uconnect, check the app for details.
4. Not Checking Gear Position
If the gear is not in “park,” remote start won’t work.
5. Forgetting Climate Settings
The car uses last climate control settings. Always set preferred temperature before turning off.
When To Use Remote Start
Remote start is most useful for:
- Cold mornings: Pre-heating cabin and seats
- Hot afternoons: Cooling down interior
- Quick errands: Keeping engine ready without unlocking
- Security reasons: Avoiding exposure in unsafe areas
But avoid using remote start in enclosed spaces, like closed garages, to prevent carbon monoxide buildup.
Troubleshooting Remote Start Problems
If remote start isn’t working:
- Check key fob battery
- Make sure all doors, hood, and trunk are closed
- Confirm vehicle is in park
- If using Uconnect, check for app updates or subscription issues
- Look for error messages in the app or on the dashboard
If problems persist, consult your owner’s manual or speak to a Jeep technician.

- Aftermarket kits: $150–$400. May require professional installation.
