Remote Start Disabled Reasons
The 2015 Jeep Grand Cherokee remote start may show as disabled due to several reasons. The system prioritizes safety and proper vehicle status before allowing remote ignition. Understanding these causes helps you troubleshoot quickly and avoid frustration.
Some common issues come from safety features that detect unsafe conditions. Others relate to the key fob or the remote start system itself. Knowing these factors can save time and effort.
Safety Features Triggering Disable
- Hood, doors, and trunk must be fully closed. A sensor may detect if they are open.
- The vehicle must be in Park (P) gear for remote start to work.
- Low fuel, oil, or coolant levels can block remote starting to prevent damage.
- A check engine light will disable remote start until the issue is fixed.
- Hazard lights need to be off. Their activation prevents remote start.
Key Fob And System Issues
- Dead or weak key fob battery often causes remote start to show disabled.
- After several failed attempts, the system locks out remote start temporarily.
- Pressing the vehicle’s start button with the brake pedal resets the system.
- Interference or a need for key fob reprogramming can disrupt remote start.
Safety Checks To Perform
Performing safety checks before using the remote start on your 2015 Jeep Grand Cherokee is essential. These checks ensure the vehicle starts only under safe conditions. The system disables remote start if it detects any issues. Follow these simple steps to avoid inconvenience and keep your vehicle secure.
Hood, Doors, And Trunk Closure
Make sure the hood is fully closed and latched. Check all doors and the trunk to confirm they are shut tight. Open or ajar compartments can trigger the remote start to disable. Sensors detect these areas to prevent starting when not secure. This prevents accidents and theft.
Check Engine Light Impact
A glowing check engine light often stops remote start from working. The system sees this as a warning of mechanical problems. Scan the vehicle for error codes and fix issues promptly. Ignoring this can lead to bigger vehicle damage. Safety comes first.
Fuel, Oil, And Coolant Levels
Check your fuel gauge to ensure enough fuel is present. Low oil or coolant levels also block remote starting. These fluids keep the engine running smoothly and prevent overheating. Monitoring these levels protects the engine from damage.
Hazard Lights Status
The hazard lights must be off to enable remote start. If the hazard lights flash, the system will not start the engine. This is a safety feature to alert you of vehicle problems. Turn off the hazard lights before trying remote start.
Vehicle In Park Position
Your Jeep must be in the Park gear for remote start to work. The system checks the gear shift to avoid accidents. Starting the vehicle in any other gear is unsafe and will disable remote start. Always confirm the vehicle is parked before activating remote start.
Key Fob Troubleshooting
Troubleshooting the key fob is crucial for resolving remote start issues on your 2015 Jeep Grand Cherokee. The key fob controls many functions, including remote start. Problems with it often cause the system to disable. Simple checks and fixes can restore its function quickly.
Replacing Dead Batteries
A dead battery is a common cause of remote start failure. Open the key fob carefully to access the battery compartment. Replace the old battery with a new one matching the exact type. Ensure the battery is properly seated to restore signal strength. Test the remote start function after replacing the battery.
Resetting The System
The system may disable after too many attempts or errors. Press the vehicle’s start button while pressing the brake pedal to reset the system. This action clears temporary faults and allows the remote start to work again. Repeat this process if the problem reoccurs.
Handling Too Many Attempts
The remote start system locks after several failed tries. This safety feature prevents unauthorized use. Wait a few minutes before trying again. Press the start button inside the vehicle to reset the lockout. Avoid multiple quick attempts to prevent disabling the system.
Reprogramming And Interference
Sometimes, the key fob loses its programming. This causes communication errors with the vehicle. Reprogram the key fob following the Jeep manual or seek professional help. Also, signal interference from other devices can block the remote start. Move away from possible interference sources and try again.

Confirm Basic Safety Conditions
Start by checking the hood, doors, and trunk. They must be fully closed and latched. A sensor may detect if any are open, disabling remote start.
