When you encounter the "Key Not Detected" message in your 2016 Dodge Journey, it can be frustrating and concerning. This issue typically arises from problems with the key fob or the vehicle's ignition system. Understanding the potential causes and solutions can help you get back on the road quickly.

Common Causes of "Key Not Detected"

The "Key Not Detected" warning can stem from several issues:

  • Dead Key Fob Battery: Even if you've recently replaced the battery, the new battery could be faulty or improperly installed.

  • Key Fob Damage: Physical damage to the key fob, such as water exposure or drops, can affect its functionality.

  • Vehicle Battery Issues: A weak or dead vehicle battery can impact the car's ability to recognize the key fob.

  • Reprogramming Required: Sometimes, the key fob may lose its programming and need to be reprogrammed to work with your vehicle.

  • Faulty Ignition System: Problems within the ignition system itself may prevent the car from detecting the key fob.

Troubleshooting Steps

Here are some effective troubleshooting steps you can take:

  • Check Key Fob Battery: Replace the battery in your key fob again, ensuring it is a high-quality battery (usually CR2032).

  • Inspect for Damage: Examine your key fob for any signs of damage. If it has been dropped or exposed to moisture, consider replacing it.

  • Use Emergency Key: If your key fob is not working, use the emergency key stored within the fob to unlock your car and start it manually.

  • Reset Vehicle Systems: Disconnecting the vehicle's battery for a few minutes may reset any electronic glitches affecting key detection.

  • Press Key Fob Against Start Button: When starting your vehicle, press the start button with the tip of your key fob while pressing down on the brake pedal. This can sometimes bypass detection issues.

  • Visit a Dealer or Locksmith: If none of these steps work, it may be necessary to visit a dealership or a qualified locksmith for reprogramming or further diagnostics.

Prevention Tips

To avoid future issues with your key fob:

  • Keep Fob Away from Electronics: Ensure that your key fob is not stored near electronic devices that could interfere with its signal.

  • Regularly Check Battery Life: Monitor your key fob's battery life and replace it proactively to avoid sudden failures.

  • Handle with Care: Treat your key fob gently to prevent physical damage.
