Common Causes
Facing issues with your Jeep Grand Cherokee’s remote start can be frustrating. Understanding the common causes can help you troubleshoot effectively. Let’s dive into two major reasons why your remote start might not be working.
Battery Issues
One common cause of remote start problems is battery issues. A weak or dead battery can prevent the system from working. This applies to both the car battery and the key fob battery. Ensure the car battery is in good condition. If the key fob battery is low, replace it. Check if the problem persists after changing the batteries.
Key Fob Malfunctions
Another frequent cause is key fob malfunctions. Sometimes, the key fob itself might be faulty. This can occur due to physical damage or internal issues. Try using a spare key fob if available. If the spare works, the original key fob might need replacement. Ensure the key fob is not damaged and is clean.
Initial Checks
Experiencing issues with your Jeep Grand Cherokee remote start can be frustrating. Before diving into complex troubleshooting, perform some initial checks. These simple steps often resolve the problem quickly.
Key Fob Battery
The key fob battery is a common culprit. A weak or dead battery can prevent the remote start from working.
- Check if the buttons on the key fob respond.
- If not, replace the battery.
- Use a small screwdriver to open the key fob.
- Replace the old battery with a new one.
Always keep a spare battery. This ensures you are not caught off-guard.
Remote Start Settings
Incorrect settings can disable the remote start feature. Verify the remote start settings in your vehicle.
- Go to the vehicle’s settings menu.
- Navigate to the remote start settings.
- Ensure the remote start is enabled.
- If disabled, enable it and save changes.
Sometimes, the settings may reset after a battery change. Always check these settings first.
Software Problems
Is your Jeep Grand Cherokee’s remote start not working? One common cause is software problems. This can be frustrating, but understanding the root causes can help you find a solution. Let’s explore two main issues: update required and system glitches.
Update Required
The remote start function relies on software. Sometimes, it needs an update. Outdated software can cause the system to malfunction. Check if your Jeep’s software is up-to-date. Follow these steps to check for updates:
- Navigate to the Settings menu on your car’s display.
- Select Software Updates.
- If an update is available, follow the on-screen instructions.
Regular updates can fix bugs and improve performance. Always keep your car’s software current to avoid remote start issues.
System Glitches
Sometimes, the remote start system may experience glitches. These are temporary and can be fixed easily. Here are some common solutions:
- Restart the car’s system. Turn off the engine, wait a few minutes, and then restart.
- Check the key fob battery. A weak battery can cause signal issues.
- Reset the remote start system. Refer to your owner’s manual for specific instructions.
If these steps do not work, consult a professional. They can diagnose and fix the issue quickly.
By addressing software problems, you can ensure your Jeep Grand Cherokee’s remote start works smoothly.
Electrical Issues
Electrical issues can cause the Jeep Grand Cherokee remote start to stop working. These problems often stem from basic electrical components. Understanding these issues can help you fix the problem quickly.
Blown Fuses
Blown fuses are a common cause of remote start issues. Fuses protect electrical circuits by breaking the connection when there is an overload. Check the fuse box under the dashboard. Look for any blown fuses. Replace them if necessary.
Wiring Problems
Wiring problems can also affect the remote start function. Wires may become damaged or disconnected over time. Inspect the wiring connected to the remote start system. Ensure all connections are secure. Fix any visible damage to the wires.
Environmental Factors
Understanding why your Jeep Grand Cherokee remote start isn’t working can be frustrating. One of the key factors is the environment. Environmental conditions can significantly impact the functionality of your vehicle’s remote start system.
Extreme Temperatures
Extreme temperatures can cause issues with your Jeep Grand Cherokee remote start. Both very hot and very cold weather conditions can affect your vehicle’s electronics.
In cold weather, the battery may lose power, causing the remote start to fail. On the other hand, in extreme heat, the electronic components may not function correctly.
To mitigate these issues, ensure your vehicle is parked in a garage during extreme weather. This simple step can help maintain optimal conditions for the remote start system.
Obstructions
Obstructions can also interfere with the remote start system. Physical barriers between the key fob and your vehicle can block the signal.
These barriers can include walls, buildings, or even other vehicles. Always try to have a clear line of sight when using the remote start.
Additionally, metal objects can block the signal. Avoid placing the key fob near metal objects or electronic devices.
By understanding and addressing these environmental factors, you can ensure your Jeep Grand Cherokee remote start works reliably.
Professional Assistance
Experiencing issues with your Jeep Grand Cherokee remote start can be frustrating. Sometimes, the problem might be simple and fixed at home. But often, it requires professional help. Seeking expert advice ensures your vehicle runs smoothly and safely.
When To Consult A Mechanic
There are times when you should seek a professional mechanic. Here are a few signs:
- The remote start fails frequently.
- The check engine light is on.
- There are unusual sounds when starting the vehicle.
- The key fob is not working even after changing the battery.
These signs indicate deeper issues. Ignoring them can lead to bigger problems. A trained mechanic can diagnose and resolve these issues.
Choosing A Service Center
Choosing the right service center is crucial. Here are some tips:
- Ensure the center is certified to work on Jeep vehicles.
- Check online reviews and ratings.
- Ask for recommendations from friends or family.

A reputable service center will provide a detailed diagnosis. They will also offer a warranty on their work. This ensures peace of mind and reliability.
In conclusion, seeking professional assistance for your Jeep Grand Cherokee remote start issues is important. It ensures your vehicle remains in top condition.
Preventive Measures
The Jeep Grand Cherokee is a reliable vehicle known for its ruggedness and comfort. However, the remote start feature can sometimes fail. To avoid this inconvenience, it’s essential to take preventive measures. These steps ensure your remote start works flawlessly every time.
Regular Maintenance
Regular maintenance is crucial for the Jeep Grand Cherokee’s remote start function. Check the battery in your key fob frequently. A weak battery can cause the remote start to fail. Replace it as soon as you notice any delay in response.
Inspect the vehicle’s main battery. A weak or dying car battery affects the remote start system. Ensure the battery terminals are clean and free of corrosion. Regularly check the car’s electrical system for any faults.
Keep the car’s internal systems in top shape. Regularly service the engine, transmission, and other key components. This ensures the vehicle runs smoothly and the remote start works correctly.
Software Updates
Software updates are vital for the remote start feature. The Jeep Grand Cherokee’s software controls many functions, including the remote start system. Regularly updating the software ensures all systems work well together.
Visit the dealership to check for the latest software updates. They can install updates that improve system performance. Some updates fix bugs that may cause the remote start to fail.
Owners can also check for software updates online. Jeep often provides information on software updates on their official website. Always follow the instructions carefully to avoid any issues during the update process.

User Errors
Experiencing issues with your Jeep Grand Cherokee’s remote start can be frustrating. Often, user errors lead to the remote start not working. Understanding common mistakes can save you time and effort.
Incorrect Sequence
One common mistake is not following the correct sequence. The remote start requires a specific button press order. First, lock the doors using the remote. Then, press and hold the remote start button for at least four seconds. Missing any step can cause the system to fail.
Manual Override
Another user error involves the manual override. If the car is in manual override mode, the remote start will not work. This mode disables the remote start function.
