2019 Dodge Journey Key Fob Battery Issues: Troubleshooting and Solutions

Experiencing a “Key Fob Not Detected” message in your 2019 Dodge Journey can be frustrating, especially when you rely on your vehicle daily. If you’ve recently encountered this problem, particularly after changing your key fob battery, you’re not alone. Many 2019 Dodge Journey owners have faced similar issues, and understanding the potential causes and solutions can save you time and money. This guide will walk you through troubleshooting steps and help you determine the best course of action to get back on the road.

One of the first and simplest things to check when you see the “Key Fob Not Detected” message is the key fob battery itself. While you might have recently replaced it, there are a few things to consider. First, ensure you used the correct type of battery. Most Dodge Journey key fobs require a CR2032 battery. Using an incorrect battery type or a battery that is old or low quality can lead to issues with signal transmission. It’s always best to use a fresh, brand-name battery for optimal performance.

To replace the battery in your 2019 Dodge Journey key fob, you’ll typically need a small flathead screwdriver. Gently pry open the key fob casing, usually starting at a small notch or seam. Once open, you’ll see the battery. Take note of the battery’s orientation (+ side up) before removing the old one. Install the new CR2032 battery in the same orientation and carefully snap the key fob casing back together.

Note: Please replace the example URL above with a valid URL of a Dodge key fob image. For example, you can use an image from a reputable source like a car parts website or a car review site. Also, create a more descriptive alt text once you have the actual image URL.

If replacing the battery doesn’t resolve the “Key Fob Not Detected” message, there are other potential culprits. Sometimes, the issue isn’t with the battery itself, but with the key fob’s programming or synchronization with your Dodge Journey. It’s possible that after the battery change, the key fob needs to be resynchronized with the vehicle’s receiver. While some online resources suggest certain key cycling methods to reset the fob, these are often unreliable for modern vehicles like the 2019 Dodge Journey.

Another possibility, though less common after a simple battery change, is a problem with the vehicle’s key fob receiver. This receiver is responsible for detecting the signal from your key fob. If the receiver is faulty or experiencing interference, it may not recognize your key fob, even with a new battery. Electrical interference from aftermarket accessories or even strong radio frequencies in certain areas can sometimes temporarily disrupt the signal.

If you’ve tried a new, correct battery and are still facing the “Key Fob Not Detected” message, it’s advisable to seek professional assistance. A qualified mechanic or your local Dodge dealership has the diagnostic tools to accurately pinpoint the issue. They can test your key fob’s signal strength, check the vehicle’s receiver, and rule out any other underlying electrical problems. Attempting complex DIY fixes without proper knowledge and tools could potentially worsen the situation or even damage your vehicle’s electronic systems.

In conclusion, while a low key fob battery is a common cause for a “Key Fob Not Detected” message in your 2019 Dodge Journey, it’s not always the sole reason. By systematically checking the battery and considering other potential issues like key fob synchronization or receiver problems, you can effectively troubleshoot the problem. When in doubt, consulting a professional ensures a proper diagnosis and repair, getting you back to driving your Dodge Journey with confidence.
