Is your Chrysler 200 not starting because of a key fob not detected error? You’re not alone. Many Chrysler 200 owners have encountered this frustrating issue. In this article, we will discuss the possible causes of the problem and provide step-by-step solutions to help you resolve it.

Key Fob Not Detected: Possible Causes and Solutions

Step 1: Battery Check

The first step in troubleshooting the key fob not detected issue is to check the battery. Even though the video narrator mentions that he doesn’t think the battery is the problem because it’s new, it’s still worth checking. Sometimes, the battery may have a weak connection or be faulty. Follow these steps:

  1. Locate the battery compartment on your key fob.
  2. Open the compartment and check if the battery is securely connected.
  3. If the battery is loose, reposition it and make sure it is properly secured.

Step 2: Proximity to Antenna

In the video, the narrator mentions a trick that worked for him to start the car. He discovered that the antenna that communicates with the key fob is located at the bottom of the console. Here’s what you can try:

  1. Hold the key fob close to the antenna.
  2. While keeping your foot on the brake pedal, push the start button.
  3. If the issue persists, move the key fob around to find the best position near the antenna.
  4. Once the car starts, keep the key fob close to the antenna until the car is fully started.

Step 3: Consider a Key Replacement

If the previous steps didn’t resolve the key fob not detected issue, it’s possible that there is a problem with the key itself. You may need to consider replacing the key. However, keep in mind that this can be an expensive option, as the narrator mentions a cost of $300 for a new key. You can try to find an alternative key if you have a spare or consult a professional locksmith for a more cost-effective solution.

Step 4: Seek Professional Help

If none of the above steps worked to resolve the issue, it would be best to take your Chrysler 200 to a certified dealership or a trusted auto technician. They have the expertise and diagnostic tools to identify and fix deeper problems with the key fob or the car’s system itself.


Experiencing a key fob not detected issue can be frustrating, especially when you’re in a hurry. However, by following the troubleshooting steps mentioned above, you have a good chance of resolving the problem on your own. Remember to check the battery, ensure proximity to the antenna, consider a key replacement, and seek professional help if necessary. With a little patience and perseverance, you’ll have your Chrysler 200 up and running smoothly again.
