The 2016 Jeep Grand Cherokee is renowned for its luxurious features, robust exterior, and exceptional off-road capabilities. Among its many appealing features, the remote start system is a convenience that many owners cherish. However, users may sometimes experience problems with the feature, leaving them frustrated and perplexed. In this article, we’ll explore why your remote start may not be working, its underlying causes, and how to troubleshoot these issues efficiently.
Understanding the Remote Start Feature
Before delving into potential issues, it’s essential to understand what the remote start feature entails. The remote start option allows drivers to warm up or cool down their vehicles from a distance, enhancing comfort before getting inside. This system not only saves time but also helps in preparing the vehicle for certain weather conditions.
Why Is Your Remote Start Not Working?
When you press the remote start button and nothing happens, it can be concerning. Below are several common reasons why your 2016 Jeep Grand Cherokee’s remote start feature may not be functioning properly.
1. Key Fob Issues
Key fobs are crucial components for the remote start function. If your key fob is malfunctioning, it may prevent the signal from reaching the vehicle. Here are some aspects to consider regarding key fobs:
- Battery Life: One of the most common reasons your key fob may not work is a dead battery. If the battery is low, the operating range will diminish, impacting its ability to send a signal to the vehicle.
- Programming Problems: If the key fob has been reprogrammed or if you’re using a duplicate that wasn’t properly coded, it may not be able to communicate with your vehicle’s starting system.
2. Jump Start and Security System
Sometimes, if the vehicle has recently received a jump start, the security system may become confused. The remote start feature often integrates closely with the vehicle’s anti-theft mechanisms. In such cases:
- Security Lockout: The security system might lock out the remote start functionality due to an unexpected electrical change.
- Check Engine Light: If the check engine light is illuminated, the remote start will often be disabled to prevent further complications. A full diagnostics check is advisable.
Troubleshooting Steps for Remote Start Challenges
If you’re encountering issues with your remote start system, take the following steps:
1. Test the Key Fob
First, determine if the problem lies with the key fob. Here’s how to test it:
- Replace the battery in the key fob. Most fobs require a CR2032 battery, which is readily available at auto parts stores or online.
- Test the key fob on another Grand Cherokee, if available, to rule out programming issues.
2. Check Your Vehicle’s Safety Features
Your Grand Cherokee may have safety features that prevent the remote start function from operating. Here’s how to check these features:
Location and Position of Vehicle
Make sure that the vehicle is in a suitable location for remote start. The system will often disable if the vehicle is in gear or if the hood is open.
Climate Control Settings
Verify if the climate control settings are appropriate. Remote start may not activate if the vehicle’s climate control features aren’t set correctly.
Diagnosing Electrical Problems
Many times, remote start issues stem from underlying electrical problems within the vehicle. Here are some key aspects to look into:
Battery Condition
Your vehicle’s battery is crucial for overall functionality. Ensure the battery is charged:
- Check for corrosion on battery terminals.
- Test the battery’s voltage to ensure it’s within operational ranges (generally 12.6 volts when fully charged).
Fuses and Wiring Issues
If the fob works but the vehicle doesn’t respond, consider looking into the fuses and wiring:
| Component | Reason for Check |
|---|---|
| Remote Start Fuse | If blown, it may prevent the system from working. |
| Wiring Connections | Loose or damaged wiring can interrupt signals between components. |
Resetting the Remote Start System
At times, resetting the remote start system can resolve various issues. Here’s a simple approach to perform a reset:
1. Disconnect the Battery
- Disconnect the negative battery cable for about 10-15 minutes.
- Reconnect the cable securely. This action can often clear any minor glitches within the vehicle’s computer system.
2. Reprogram the Key Fob
If you suspect the key fob might be the issue after resetting the battery, reprogram it following these steps:
- Enter the vehicle and close all doors.
- Insert the key into the ignition and turn it to the ON position, without starting the engine.
- Press the lock button on the driver’s door.
- Test the remote start function again.
Seeking Professional Help
If the above troubleshooting steps do not yield any results, it may be time to consult a professional. Trained technicians have the necessary tools and experience to diagnose problems efficiently, especially concerning electronic systems.
When to Visit a Dealership or Mechanic
Consider taking your 2016 Jeep Grand Cherokee to a dealership or certified mechanic if:
- You hear unusual sounds when attempting to use the remote start.
- The dashboard shows warning lights besides the check engine light.
- The remote start doesn’t respond after replacing the key fob battery.

What is the purpose of the remote start feature in my 2016 Jeep Grand Cherokee?
The remote start feature in your 2016 Jeep Grand Cherokee allows you to start your vehicle from a distance, ensuring that the cabin is warmed up in the winter or cooled down in the summer before you get inside. This feature adds convenience to your driving experience, especially in extreme weather conditions, by allowing you to regulate the car’s interior temperature without having to be in the vehicle.
Additionally, remote start can help reduce the wear on your engine by allowing it to warm up adequately before driving. This is especially beneficial in colder climates, where starting the engine and driving immediately could cause additional strain on the vehicle’s components.
Why isn’t my remote start function working?
Several factors could cause the remote start function to malfunction in your 2016 Jeep Grand Cherokee. One of the most common issues is low battery power in the key fob. If your key fob battery is dying, it may not transmit the signal strong enough to start the vehicle. Replacing the battery in your remote may resolve the issue.
Another reason could be that one of the security features is preventing remote start from activating. For instance, if the gear shift is not in the correct position or if the hood is ajar, the system will not permit the vehicle to start remotely. Ensuring that all conditions for remote start are met can help troubleshoot the underlying issues.
How do I know if my remote start feature is enabled?
You can check the owner’s manual for your 2016 Jeep Grand Cherokee to find information about the remote start feature’s availability and how to confirm it is enabled. Typically, the remote start system is enabled when the vehicle is initially purchased, but it can be disabled for various reasons, such as technical issues or after-marquee modifications.
Additionally, if your remote start function lights up when you attempt to use it, this is a good indicator that it is enabled. If the feature is not working despite following the instructions in the manual, it may be worth consulting with a dealership or qualified mechanic to ensure that there isn’t a broader mechanical or electrical issue at play.
Can I use the remote start function without the key fob?
The remote start function for your 2016 Jeep Grand Cherokee requires the use of the key fob. It is designed to operate specifically with the factory-issued keyless entry system, which includes security features that prevent unauthorized starting of the vehicle. Using a different type of remote or key could compromise the vehicle’s security system.
Using a smartphone app or other non-factory methods to start the vehicle remotely could void any warranties or cause issues with the vehicle’s electronics. It is recommended to always use the original key fob designed for your vehicle to ensure proper functionality and security.
What steps should I take if my remote start works intermittently?
If your remote start function works intermittently, it is important to start by checking the key fob and its battery. Sometimes, low battery power can result in sporadic operation. Replacing the battery might solve the problem. Additionally, check if there’s any damage to the fob or if it requires reprogramming.
If the key fob appears to be functioning correctly, investigate if any particular conditions are inhibiting the remote start, such as obstacles blocking the signal or interferences from other electronic devices. If the issue persists, consulting a professional service center to perform a diagnostic may be necessary to ensure everything is functioning as intended.
Is there a way to troubleshoot remote start issues on my own?
Yes, there are several basic troubleshooting steps you can take to address remote start issues with your 2016 Jeep Grand Cherokee. Start by making sure all doors, the trunk, and the hood are securely closed. The remote start feature typically won’t operate if any of these are open, as a safety measure.
Next, try to reprogram your remote if needed. This process generally involves inserting the key in the ignition while pressing specific buttons on the fob. Refer to your owner’s manual for detailed instructions. If these steps do not resolve the problems, it might be necessary to reach out to a dealership for a more in-depth inspection.
Can aftermarket remote start systems be compatible with my 2016 Jeep Grand Cherokee?
Aftermarket remote start systems can be compatible with your 2016 Jeep Grand Cherokee, but it is essential to conduct thorough research.
