Experiencing a “Key Fob Not Detected” message in your 2020 Dodge Journey can be frustrating, especially when you rely on your vehicle daily. Many drivers encounter issues with their key fobs, and one of the most common culprits is the key fob battery. If your Dodge Journey is displaying this message, or if you’re finding your key fob range diminishing, understanding the battery is the first step in troubleshooting.
Often, the solution is as simple as replacing the key fob battery. These fobs typically use a CR2032 type battery, which is widely available and relatively inexpensive. You might notice symptoms like intermittent starting, the inability to remotely lock or unlock your doors from a distance, or the dashboard displaying the dreaded “Key Fob Not Detected” even when the fob is inside the car.
Before assuming a more complex problem, changing the battery is a practical first step. Refer to your 2020 Dodge Journey owner’s manual for the specific battery type and instructions on how to safely open your key fob casing. Usually, this involves a small flathead screwdriver to gently pry open the case, replace the old battery with a fresh CR2032, ensuring correct polarity (+ and – sides are aligned properly), and then snapping the fob back together.
If replacing the battery doesn’t resolve the issue, there could be other factors at play. While less common, problems can range from a faulty key fob requiring replacement or reprogramming, to issues within the vehicle’s receiver system itself. In some cases, interference from external sources can temporarily disrupt the key fob signal.
For a 2020 Dodge Journey, ensuring your key fob battery is fresh is essential maintenance. If problems persist after a battery replacement, it’s advisable to consult a qualified mechanic or your Dodge dealership to diagnose potential underlying issues within your vehicle’s keyless entry system. They can determine if the problem lies within the fob itself, the car’s receiver, or another component, ensuring you get back on the road with a functioning key fob.
