💡 Pro Tips:

1. Check for physical damage: Inspect the key fob for any physical damage, such as water damage or broken buttons, that may be causing it to not be detected.

2. Check the range: Move closer to the vehicle and try again, as a weak signal can sometimes prevent the key fob from being detected.

3. Clean the contacts: Use a cotton swab and rubbing alcohol to clean the contacts on the key fob and in the battery compartment, as dirty contacts can interfere with the connection.

4. Reprogram the key fob: Try reprogramming the key fob using the vehicle’s manual or seek assistance from a dealer or locksmith.

5. Replace the key fob: If all else fails, it may be necessary to replace the key fob with a new one.

1. Dead Battery: Replace Key Fob Battery

Is your 2018 Jeep Cherokee key fob not being detected? One common issue that may cause this problem is a dead battery in the key fob itself.

Luckily, replacing the key fob battery is a simple and inexpensive solution. Here are the steps to do it:

  1. Locate the small indentation or slot on your key fob.

This is usually on the side or bottom of the fob. 2.

Use a small flat-head screwdriver or a coin to pry open the key fob casing. 3.

Take out the old battery and carefully dispose of it. 4.

Insert a new battery, making sure it is positioned correctly. The positive side should be facing up.

  1. Snap the key fob casing back together.

Note: It is important to use the correct battery type for your Jeep Cherokee key fob. Refer to the owner’s manual or consult a professional if you are unsure about the battery size or type.

2. Incorrect Usage: Learn Correct Key Fob Usage

Sometimes, the issue may not be a dead battery but simply incorrect usage of the key fob. Each Jeep Cherokee model and trim level may have specific instructions on how to use the key fob properly.

Here are some general guidelines to follow:

  • Make sure you are within the range specified by the manufacturer. Typically, this is within a few feet of the vehicle.

  • Press the unlock or lock button firmly and hold it for a few seconds. This may help establish a proper connection between the key fob and the Jeep’s system.

  • If your key fob has multiple buttons, familiarize yourself with their functions. Some models may have additional features like remote start or power liftgate control.

  • Pro Tip: Consider replacing the battery in your key fob even if it is not dead. Weak batteries can still cause issues with the key fob’s performance.
  • 3. Wrong Key Fob Programming: Check Security Code

    Another potential reason why your 2018 Jeep Cherokee key fob is not being detected is incorrect programming. The key fob needs to have the correct security code stored and transmitted to the vehicle for it to work properly.

    Here’s what you can do:

    • Verify that you are using the correct key fob for your Jeep Cherokee. If you have multiple key fobs, try using a different one to see if the issue persists.

    • Consult your vehicle’s user manual or contact a dealership to find out how to reprogram the key fob. The process may vary depending on your specific model and trim level.

    4. Broken Buttons Or Keys: Inspect For Damage

    A key fob with broken buttons or keys can also lead to detection issues. Take a close look at your key fob and check for any cracks, scratches, or physical damage that may affect its functionality.

    If you notice any damage, consider replacing the key fob.

  • Pro Tip: If only specific buttons on your key fob are not working, you may be able to replace those individual buttons instead of the entire fob.
  • 5. Faulty Door Lock System Or Panoramic Sunroof: Check Components

    Sometimes, the key fob detection problem may not be due to the key fob itself, but rather issues with the vehicle’s door lock system or panoramic sunroof. Here are some steps to diagnose and address these potential causes:

    • Test the door lock system by manually locking and unlocking the doors using the key or the internal switches. If the locks do not respond correctly, there may be an issue with the lock actuators or wiring that needs to be addressed by a professional.

    • Check the panoramic sunroof for any obstructions or debris that may prevent proper operation. Clear any obstructions and ensure that the sunroof is closed completely before attempting to use the key fob.

    6. Interference From Multiple Wireless Devices: Remove Or Distance Devices

    Wireless interference from other devices can sometimes disrupt the signal between the key fob and your Jeep Cherokee. To mitigate this potential issue, follow these steps:

    • Remove or distance other wireless devices from the proximity of your key fob. This includes cell phones, tablets, and other key fobs or remote devices.

    • Test the key fob’s performance in an area with minimal wireless interference.

    If none of the above troubleshooting steps resolve the issue with your 2018 Jeep Cherokee key fob, it may be necessary to consult a dealership or auto expert for further assistance. They will have the expertise and tools to diagnose and address any underlying problems.

    Remember, it’s always better to seek professional help if you are unsure or unable to resolve the issue on your own.

    With these troubleshooting tips and guidelines, you should be able to address the issue of your 2018 Jeep Cherokee key fob not being detected. Remember to check the battery, ensure correct usage, verify programming, inspect for damage, check the door lock system and panoramic sunroof, and minimize wireless interference.

    By following these steps, you can get your key fob working again and enjoy the convenience it provides for your Jeep Cherokee.
