Common Issues
Experiencing problems with your Jeep Wrangler’s remote start can be frustrating. Understanding the common issues can help you resolve them quickly. Let’s explore some of the typical problems that might cause your remote start to malfunction.
Battery Problems
One of the most common issues is battery problems. If your car’s battery is weak, the remote start might not function properly. Check the battery voltage. It should be around 12.6 volts when the car is off. If it’s lower, the battery might need a charge or replacement.
The key fob’s battery is also crucial. A dead or weak key fob battery can prevent the remote start from working. Replace the key fob battery regularly. Use the correct type of battery specified in the user manual.
Faulty Key Fob
A faulty key fob can be another major issue. If the key fob is damaged or malfunctioning, it won’t communicate with your Jeep’s system. Here are some signs of a faulty key fob:
- Buttons not responding
- Intermittent functionality
- Visible damage to the fob
If you experience any of these issues, try resetting the key fob. Sometimes, reprogramming the key fob can also solve the problem. If not, you may need a replacement.
| Problem | Solution |
|---|---|
| Weak car battery | Charge or replace the battery |
| Dead key fob battery | Replace the key fob battery |
| Faulty key fob | Reset or replace the key fob |
Checking The Battery
If your Jeep Wrangler’s remote start is not working, the battery might be the problem. The battery powers the remote. A weak or dead battery can prevent it from working. Checking the battery is easy and can save you a trip to the mechanic.
Testing Battery Voltage
Use a voltmeter to test the battery’s voltage. First, remove the battery from the remote. Then, set the voltmeter to measure DC voltage. Place the positive lead on the battery’s positive terminal. Place the negative lead on the battery’s negative terminal. Check the reading on the voltmeter.
A healthy battery should read around 3 volts. If the voltage is below 2.5 volts, the battery is weak. A low voltage means it’s time to replace the battery.
Replacing The Battery
Replacing the battery is simple. First, buy a new battery that matches your remote. Open the remote’s battery compartment. Remove the old battery and dispose of it properly. Insert the new battery, making sure the positive and negative ends match the markings.
Close the battery compartment. Test the remote to see if the problem is fixed. If the remote start works, the battery was the issue.
Key Fob Inspection
Experiencing issues with your Jeep Wrangler remote start not working can be frustrating. One of the first steps in troubleshooting is to inspect the key fob. This essential device may be the root cause of the problem. Let’s dive into the key aspects of key fob inspection.
Checking For Physical Damage
Start by examining the key fob for any physical damage. Look for cracks, broken buttons, or any signs of wear and tear. Damaged key fobs can cause remote start issues.
- Check the buttons: Are they intact and functional?
- Inspect the casing: Any visible cracks or splits?
- Examine the battery compartment: Is it secure and clean?
Physical damage often leads to internal issues. If you notice any damage, consider replacing the key fob or seeking professional repair services.
Reprogramming The Key Fob
If there is no visible damage, the next step is to reprogram the key fob. Sometimes, the fob can lose its programming, causing it to stop working with your Jeep Wrangler.
- Enter your Jeep and close all doors.
- Insert the key into the ignition.
- Turn the key to the “On” position, but do not start the engine.
- Press and hold the “Lock” button on your key fob for 5 seconds.
- Turn the key back to the “Off” position and remove it from the ignition.
After following these steps, try the remote start function again. If it still doesn’t work, you may need to consult a professional or your dealership for further assistance.
Software Glitches
Software glitches can often cause your Jeep Wrangler remote start not to work. These glitches may arise from outdated software or small bugs within the system. Understanding how to tackle these glitches can save you a lot of trouble. Let’s explore two simple methods to fix these software glitches: resetting the system and updating the software.
Resetting The System
First, try resetting the system. Turn off your Jeep and remove the key from the ignition. Wait for about 10 minutes. This allows the system to reset itself. Next, insert the key back into the ignition and turn it to the “On” position without starting the engine. Finally, try using the remote start again. This simple step can often resolve minor software issues.
Updating Software
An outdated software version can also cause remote start problems. Check if there is a software update available for your Jeep Wrangler. You can do this by visiting the official Jeep website or contacting your dealer. Follow the instructions provided to update the software. This process usually involves downloading the update to a USB drive and then installing it in your Jeep. After the update, try the remote start again. Keeping your software up-to-date is crucial for smooth operation.
Signal Interference
Experiencing issues with your Jeep Wrangler remote start? Signal interference might be the cause. This common problem can prevent your remote start system from working correctly. Let’s explore two primary sources of signal interference: nearby electronic devices and environmental obstacles.
Nearby Electronic Devices
Electronic devices can create signal interference. This interference disrupts the communication between your remote and the Jeep. Common culprits include mobile phones, laptops, and Wi-Fi routers. These devices emit signals that can interfere with your remote start system. Try moving these devices away from your Jeep. This can often resolve the issue.
Environmental Obstacles
Environmental obstacles can also affect your remote start. Buildings, trees, and even parked cars can block the signal. This blockage can prevent your remote from connecting to the Jeep. If possible, try to start your Jeep in an open area. This reduces the chance of signal interference. Also, ensure you are within the recommended range for the remote start system.

Remote Start Settings
The remote start feature on your Jeep Wrangler is a handy tool. It allows you to start the engine from a distance. This can be very useful in extreme weather conditions. However, if your remote start is not working, it could be due to the settings. Let’s explore the remote start settings and how to ensure they are configured correctly.
Verifying Settings
First, check the vehicle’s settings menu. Ensure the remote start option is enabled. This can be done through the Uconnect system. Follow these steps:
- Press the ‘Settings’ button on the Uconnect screen.
- Select ‘Convenience’ from the menu.
- Ensure the ‘Remote Start’ option is turned on.
If the remote start is enabled and still not working, there may be other settings affecting it.
Adjusting Preferences
Sometimes, adjusting preferences can help resolve issues. Check the following preferences:
- Make sure the doors are locked. The remote start won’t work if they are not.
- Ensure the hood is closed. An open hood can disable the remote start.
- Check if the vehicle is in ‘Park’. The remote start only works in this gear.
After checking these preferences, try using the remote start again. If it still does not work, consult the user manual or a professional.
Professional Diagnosis
Experiencing issues with your Jeep Wrangler’s remote start can be frustrating. If basic troubleshooting steps don’t solve the problem, you may need a professional diagnosis. This involves consulting a technician who can use diagnostic tools to identify and fix the issue.
Consulting A Technician
Sometimes, the problem with the remote start can be complex. Consulting a technician ensures that you get an expert opinion. They have the knowledge and experience to identify the issue quickly. Here are some steps they might take:
- Check the battery in the key fob.
- Inspect the remote start system.
- Evaluate the vehicle’s electrical system.
A technician can save you time and ensure the problem is fixed correctly.
Using Diagnostic Tools
Technicians use specialized diagnostic tools to pinpoint the issue. These tools can read error codes from the car’s computer system. This helps in identifying any underlying problems that might not be visible. Here is how they do it:
- Connect the diagnostic tool to the car’s OBD-II port.
- Read and interpret the error codes.
- Perform tests based on the error codes.
Using diagnostic tools ensures an accurate and efficient diagnosis. This can prevent further issues and help maintain your vehicle’s performance.
