Owning a 2015 Jeep Grand Cherokee is exciting, especially with modern features like remote start. This system lets you start your SUV from a distance. It’s ideal for warming up the engine or cooling the cabin before you drive. But many owners face a frustrating message: “Remote Start Disabled.” If you’re seeing this, you’re not alone. Let’s explore why this happens, how to fix it, and what you should know to keep your Grand Cherokee’s remote start working smoothly.
What Is Remote Start?
The remote start feature uses your key fob to start the vehicle without entering it. In the 2015 model, you press the button twice, and the engine starts. This is useful for cold mornings or hot afternoons. The system checks certain conditions before starting. If something’s wrong, it disables itself for safety.
Common Reasons For Remote Start Disabled
There are several causes for this issue. Here’s a breakdown:
- Check Engine Light: If this light is on, the system won’t allow remote start.
- Low Battery: Weak battery in the vehicle or key fob can disable remote start.
- Hood Ajar: If the hood isn’t fully closed, the system stops remote start.
- Transmission Problems: Any error in transmission disables the feature.
- Coolant or Oil Issues: Low coolant or oil levels stop remote start.
- Fuel Level: If fuel is very low, the system won’t work.
Comparison Of Causes
Here’s a quick look at how each cause affects the system:
| Cause | Effect on Remote Start | Ease of Fix |
|---|---|---|
| Check Engine Light | Disabled | Requires diagnosis |
| Low Battery | Disabled | Replace or recharge |
| Hood Ajar | Disabled | Close hood |
| Transmission Error | Disabled | Service needed |
| Coolant/Oil Low | Disabled | Refill fluid |
| Low Fuel | Disabled | Refuel |
How To Fix Remote Start Disabled
If your remote start isn’t working, try these steps:
- Check dashboard for warning lights.
- Make sure the hood is closed.
- Inspect battery condition.
- Fill oil and coolant if low.
- Refuel if the tank is almost empty.
Step-by-step Example
Imagine your key fob won’t start the engine. You notice the check engine light is on. First, read the error code using an OBD-II scanner. If it’s a minor issue (like a loose gas cap), fix it and clear the code. Try remote start again. If it still doesn’t work, check the hood, battery, and fluid levels.
Non-obvious Insights
Most beginners miss two important points:
- Remote start only works if all doors are closed and locked.
- After three failed remote start attempts, the system locks out for safety. You must use the key to start the engine before trying again.
Dealer Vs. Diy Solutions
You can fix simple problems yourself, like closing the hood or replacing the key fob battery. For deeper issues, like transmission errors or persistent check engine lights, visit a Jeep dealer. They have tools to diagnose and reset the system.
Dealer And Diy Costs
Here’s a quick cost comparison:
| Fix Type | Typical Cost | Time Needed |
|---|---|---|
| DIY (battery/key fob) | $10–$50 | 10–30 minutes |
| Dealer diagnosis | $75–$150 | 1–2 hours |
| Fluid refills | $30–$70 | 15–30 minutes |
Preventing Remote Start Issues
To avoid “Remote Start Disabled” messages:
- Maintain regular vehicle service.
- Check battery health every 6 months.
- Monitor oil and coolant levels monthly.
- Close all doors and the hood properly.
A well-maintained Grand Cherokee rarely faces remote start problems.
Remote Start System Data
The 2015 Jeep Grand Cherokee’s remote start system has these specs:
| Feature | Specification |
|---|---|
| Max Range | Up to 300 feet |
| Engine Run Time | 15 minutes per start |
| Number of Attempts | 3 consecutive |

Why Safety Matters
Jeep disables remote start when safety is at risk. For example, if fluids are low, starting the engine could damage it. If the hood is open, someone could get hurt. These features protect both the car and its passengers.
Real-world Example
A driver in winter tries to use remote start. The system fails. After checking, he sees the hood latch sensor is dirty. Cleaning it restores remote start. This shows that small issues can cause big problems.
When To Seek Professional Help
If you’ve tried all basic steps and remote start is still disabled, contact your local Jeep dealer. They can scan the system for hidden issues. Ignoring persistent problems can lead to bigger repairs.
