Starting your Jeep Grand Cherokee from a distance is more than just a cool trick—it can warm up the cabin on a cold morning or cool it down before you even open the door. Many owners don’t realize their Jeep may already include this feature, or that using it correctly can extend comfort and convenience. This guide will show you how to remote start your Jeep Grand Cherokee, explain which models include the feature, cover common mistakes, and answer the most frequent questions.
Understanding Remote Start In Jeep Grand Cherokee
Remote start lets you turn on your vehicle’s engine from outside using a key fob or a mobile app. Most Jeep Grand Cherokee models from 2011 and newer offer this feature, either standard or as an option. Remote start is especially popular in cold or hot climates, but many owners overlook important details that make a difference in daily use.
Key Features Of Remote Start
- Automatic climate control activation: Heats or cools the cabin to preset levels.
- Engine runs for a set time: Usually 15 minutes, then shuts off if not driven.
- Security: Doors stay locked and the vehicle cannot be driven without the key.
Not all remote start systems are the same. Factory-installed options work seamlessly, while aftermarket systems sometimes behave differently.
How To Remote Start Your Jeep Grand Cherokee
The process is easy, but missing a step can lead to confusion. Here’s a step-by-step guide for most modern Grand Cherokees (2014 and newer):
- Lock the doors: Press the lock button on your key fob. This is required for safety.
- Press and hold the remote start button: Look for the circular arrow button (usually marked with “x2”).
- Wait for confirmation: The turn signals will flash and the engine will start. On newer models, you may also hear a beep.
If successful, your Jeep will run for 15 minutes. If you do not enter the vehicle and press the brake with the key inside, it will shut off automatically.
Starting Your Jeep With The Uconnect App
Some models support remote start via the Uconnect app. This allows you to start your car from anywhere with cell service.
- Register your vehicle with Uconnect.
- Open the app and select the remote start function.
- Follow on-screen prompts to send the command.
This feature may require a paid subscription after the initial trial period.
Which Jeep Grand Cherokee Models Have Remote Start?
Not every Grand Cherokee comes with remote start. The feature is most common on the following trims and years:
| Model Year | Trim Level | Remote Start |
|---|---|---|
| 2014-2024 | Limited, Overland, Summit, Trailhawk | Standard |
| 2011-2013 | Laredo, Limited, Overland | Optional |
| 2017-2024 | All (excluding base Laredo) | Standard |
If your key fob has the circular arrow button, your Jeep likely has remote start. For older models, check the owner’s manual or ask your dealer.
Common Problems And Solutions
Many drivers experience issues when trying to remote start their Jeep Grand Cherokee. Here are the most common problems and what to do:
- Doors not locked: The system will not start if any door is open or unlocked.
- Low fuel: If the fuel level is very low, remote start may be disabled to prevent running out of gas.
- Check engine light on: The system will not work if there are active engine faults.
- Battery issues: Weak key fob batteries can prevent remote commands.
Quick tip: If remote start fails, try locking the doors again, wait a few seconds, and attempt the process. Always keep your key fob battery fresh.
Comparing Key Fob And App Remote Start
Both methods have advantages. Here’s a quick look at how they compare:
| Method | Range | Reliability | Extras |
|---|---|---|---|
| Key Fob | Up to 300 feet | Very high | No subscription needed |
| Uconnect App | Unlimited (cell service required) | May be affected by network | Extra features (lock/unlock, location) |
For most users, the key fob is simpler and more reliable, but the app adds flexibility when you’re far from your vehicle.
Safety And Legal Considerations
Remote start is designed with safety in mind. The vehicle will not move unless you unlock it with your key and press the brake pedal. However, local laws may restrict idling vehicles, especially in urban areas. Always check your area’s rules to avoid fines.
Never use remote start in enclosed spaces, like a garage. Engine exhaust can quickly fill the area with carbon monoxide, which is extremely dangerous.
Tips For First-time Users
- Practice in your driveway before relying on remote start in public places.
- Use climate presets: Set your heater, defroster, or air conditioning before you shut off the vehicle so it activates automatically when you remote start.
- Don’t leave valuables in plain sight: While your car stays locked, a running engine can still attract attention.
A less obvious tip: If you schedule regular vehicle maintenance, ask your service advisor to check the remote start system, especially if you notice changes in behavior.
What To Do If Remote Start Isn’t Working
If your Jeep Grand Cherokee’s remote start stops working, try these steps before visiting a dealer:
- Check all doors and hood: Must be fully closed.
- Look for warning lights: Any dashboard alerts can block remote start.
- Replace the key fob battery: Even a weak battery can prevent operation.
- Consult the owner’s manual: Some special modes (like valet or transport) can disable remote start.
If these steps don’t help, a professional diagnostic at a certified Jeep service center may be necessary.
