The remote start feature in the Jeep Grand Cherokee is a popular convenience. It lets you start your vehicle from a distance, warming up the cabin or cooling it down before you enter. But sometimes, owners face a frustrating message: “Remote Start Disabled.” If you’re experiencing this, you’re not alone. Let’s explore why this happens, what you can do, and how to prevent it.
What Causes Remote Start To Be Disabled?
Several factors can trigger the remote start disabled warning. Some are simple, while others may require professional help.
1. Low Battery
Both the vehicle’s main battery and the key fob battery play a role. If either is weak, the system may not operate.

2. Check Engine Light
When the check engine light is on, remote start is often disabled for safety reasons. The car’s computer wants you to address any engine issue first.
3. Hood Not Fully Closed
The remote start system checks if the hood is closed. If the sensor doesn’t confirm it, the function won’t activate.
4. Transmission Not In Park
If your Grand Cherokee isn’t in “Park,” remote start won’t work. This prevents the car from moving unexpectedly.
5. Faulty Sensors
A malfunctioning hood, brake, or door sensor can send incorrect signals, disabling remote start.
6. System Overheating
If the engine was recently running hot, the system may temporarily block remote start to protect the vehicle.
7. Too Many Failed Attempts
After several failed remote start tries, the system may lock out further attempts for a short time.
How To Fix Jeep Grand Cherokee Remote Start Disabled
You can often solve the issue with simple steps. Here’s what to do:
1. Check The Battery
Replace the key fob battery if needed. If your car battery is weak, have it tested or replaced.
2. Scan For Trouble Codes
Use an OBD-II scanner to check for error codes. Address any issues that trigger the check engine light.
3. Inspect Hood And Door Sensors
Ensure the hood is fully closed. Clean the sensor area if dirty.
If a sensor is broken, it may need replacement.
4. Verify Gear Position
Make sure your vehicle is in “Park. ” If the gear selector is faulty, a mechanic should inspect it.
5. Wait And Retry
If you’ve made several failed attempts, wait a few minutes before trying again.
6. Reset The System
Disconnect the battery for a few minutes, then reconnect. This can reset some electronic systems.
Example: Sensor Troubles
A Jeep owner reported that their remote start stopped working after washing the car. Water had entered the hood sensor, causing a false “hood open” signal.
Cleaning and drying the sensor restored the feature.

Jeep Grand Cherokee Remote Start Vs Other Brands
Let’s compare the Grand Cherokee remote start with similar SUVs.
| Model | Remote Start Range | Common Issues |
|---|---|---|
| Jeep Grand Cherokee | ~300 feet | Low battery, sensors, check engine light |
| Ford Explorer | ~200 feet | Low battery, door open, brake sensor |
| Toyota Highlander | ~250 feet | Engine codes, hood sensor, key fob battery |
The Grand Cherokee offers one of the longest ranges. Its issues are similar to competitors, but hood sensor faults are more common.
Preventing Remote Start Problems
You can reduce the chance of remote start being disabled with regular care.
- Check battery health every six months.

These simple habits help keep your remote start working reliably.
Data: Jeep Grand Cherokee Remote Start Disabled Frequency
Surveys show remote start issues are more common with older vehicles.
| Vehicle Age | Percent Reporting Disabled Remote Start |
|---|---|
| 0-3 years | 8% |
| 3-6 years | 17% |
| 6+ years | 31% |
As your Jeep ages, the chance of remote start problems increases. Regular maintenance can lower this risk.
When To See A Professional
Some issues require expert diagnosis. If you’ve tried the basic fixes and remote start is still disabled, seek help if:
- The check engine light remains on
- Sensors show errors after cleaning
- The system won’t reset after battery reconnection
- Gear selector or brake sensors don’t work properly
A qualified mechanic can scan your vehicle’s computer and pinpoint the fault.
Non-obvious Insights About Jeep Grand Cherokee Remote Start
- Climate Control Sync: When you use remote start, your Jeep tries to adjust the climate based on the last settings. If your climate control is malfunctioning, this can block remote start.
- Custom Settings Conflict: Some custom settings, like aftermarket alarms or remote starters, can interfere with the factory system. Disabling or reprogramming these may restore remote start.

Following these steps usually solves the problem.
