How Jeep Remote Start Systems Work
A Jeep remote start system is designed to offer convenience by allowing you to start your
vehicle remotely. Here’s a breakdown of the key components and their functions:
Key Components
- Key Fob: This handheld device contains a transmitter that sends a signal to the vehicle’s receiver. It typically includes buttons for starting the engine, locking/unlocking doors, and other functions.
- Receiver: Installed in the vehicle’s interior, the receiver picks up the signal from the key fob and communicates with the vehicle’s control module.
- Control Module: The control module processes the signal received from the fob and sends a command to the vehicle’s ignition system to start the engine.
- Ignition System: Once the control module sends the start command, the ignition system engages to start the engine.
- Safety Features: Modern systems include safety features such as ensuring the vehicle is in Park (for automatic transmissions) or Neutral (for manual transmissions) before starting the engine to prevent accidents.
Troubleshooting Guide: 13 Potential Causes
If your Jeep remote start isn’t working, several issues might be at play. Here’s a detailed troubleshooting guide to help you identify and resolve the problem.
1. Dead Remote Battery
A dead battery in the key fob is a common issue that can prevent the remote start system from working. Without sufficient power, the fob can’t communicate with the vehicle’s receiver.
Solution: Replace the battery in the remote fob. Most fobs use CR2032 batteries, which are readily available at most electronics stores.
2. Open Hood
Many remote start systems are designed not to operate if the hood is open for safety reasons.
Solution: Ensure the hood is fully closed. If the hood latch is faulty or misaligned, it may need adjustment or repair.
3. Transmission in Park or Neutral
The remote start system requires the vehicle to be in Park (for automatics) or Neutral (for manuals) to ensure safety.
Solution: Verify that your vehicle is in the correct gear. For automatics, make sure it’s in Park. For manuals, ensure it’s in Neutral.
4. Faulty Key Fob
A malfunctioning key fob could be the cause of the problem. This could be due to physical damage or internal issues with the fob.
Solution: Test the key fob with a spare if available. If the spare works, replace or repair the original fob. Most auto parts stores can help with this.
5. System Programming Issues
If the remote start system has lost its programming, it may not function correctly.
Solution: Follow your Jeep’s owner manual to reprogram the remote start system. If reprogramming doesn’t work, consult a professional.
6. Low Battery in Vehicle
A low vehicle battery can affect the remote start system’s performance, as it might not provide enough power.
Solution: Check the vehicle’s battery charge and replace it if necessary. A well-charged battery is crucial for the remote start system to work effectively.
7. Faulty Remote Start Module
The remote start module itself might be malfunctioning or damaged.
Solution: Have the module inspected by a professional. If it’s faulty, it will likely need replacement.
8. Security System Issues
The vehicle’s security system can sometimes interfere with the remote start system.
Solution: Check if the security system is causing interference. Resetting or reprogramming the security system might resolve the issue. Consult your owner’s manual for guidance.
9. Ignition System Problems
Problems with the ignition system can prevent the remote start from functioning.
Solution: Have a mechanic check the ignition system. Issues with ignition coils, wiring, or other components might need to be addressed.
10. Engine Temperature
Some remote start systems won’t operate if the engine temperature is too low or too high.
Solution: Check the engine temperature and wait until it reaches a suitable range before attempting to start it remotely.
11. Door or Window Open
The remote start system might not engage if a door or window is open.
Solution: Ensure that all doors and windows are closed and secured properly.
12. Remote Start Disabled
Sometimes the remote start feature may be disabled due to settings or security features.
Solution: Verify that the remote start feature is enabled in the vehicle’s settings. Consult your owner’s manual for instructions on how to enable it.
13. Software Glitches
Occasional software glitches can interfere with the remote start system.
Solution: Restart your vehicle and try using the remote start again. If problems persist, consult a professional for a software update or reset.
Quick Fixes: 9 Easy Steps
If you need immediate solutions, here are nine quick fixes to try:
1. Replace the Remote Battery
If your remote fob isn’t working, replacing the battery is a straightforward solution. Open the remote and insert a new battery.
2. Check Gear Position
Ensure the vehicle is in Park (for automatics) or Neutral (for manuals). Adjust the gear position as necessary.
3. Close the Hood
Verify that the hood is securely closed. Address any issues with the latch or sensor if needed.
4. Check Door and Window Status
Ensure all doors and windows are closed and properly secured. Open doors or windows can prevent the remote start from functioning.
5. Restart the Vehicle
Turn off the vehicle completely and then restart it. This can reset the system and resolve minor issues.
6. Turn Off Hazard Lights
Make sure the hazard lights are turned off, as they can interfere with the remote start system.
7. Ensure Proper Parking
Check that the vehicle is parked on a level surface and in the correct position. An unusual parking position can affect remote start functionality.
8. Check for Security System Issues
Ensure that the security system isn’t causing interference. Reset or reprogram the security system if needed.
9. Test with a Spare Remote
If you have a spare remote, test it to determine if the issue lies with the original remote. Replace or repair the malfunctioning remote as necessary.
Recommendations for Remote Start Kits
If you’re looking to purchase a new remote start system for your Jeep, consider the following tips:
1. Range
Choose a remote start system with a range that suits your needs. Systems with extended ranges can be useful if you need to start your vehicle from a considerable distance.
2. Compatibility
Ensure that the system is compatible with your Jeep model and year. Check the manufacturer’s specifications to avoid issues with installation and operation.
3. Features
Look for additional features such as smartphone integration, keyless entry, and security enhancements. Advanced features can offer greater convenience and security.
4. Installation
Professional installation is recommended to ensure proper integration with your vehicle. Incorrect installation can lead to operational issues and may void the warranty.
