Experiencing a “Key Fob Not Detected” message in your Dodge Journey after replacing the key fob battery can be frustrating. Many Dodge Journey owners encounter this problem, where despite a fresh battery, the vehicle fails to recognize the key fob. One Dodge Journey owner recently shared their experience, detailing how their 2016 model displayed this error after a battery change, preventing the car from starting, even with a brand new car battery. They noted that while the key fob buttons for locking and unlocking still worked, the crucial car functionalities were disabled. Let’s explore why this might happen and what troubleshooting steps you can take.
It’s unexpected when replacing your Dodge Journey Key Fob Battery, a seemingly simple task, leads to more complications. Typically, a low key fob battery is the culprit when you see warning messages or experience intermittent key fob function. However, if you’ve just installed a new battery and are now facing a “Key Fob Not Detected” error, several factors could be at play.
One of the first things to check is the battery itself. Ensure you’ve installed the correct type of battery for your Dodge Journey key fob. Refer to your owner’s manual for the specific battery type required. Also, double-check the battery polarity. Incorrectly inserting the battery, even if it fits, will prevent the key fob from working correctly. Sometimes, even new batteries can be faulty, so trying a different new battery might be a quick solution.
Beyond the battery, the issue might lie in the key fob’s programming or the vehicle’s receiver. While less common after a simple battery change, it’s possible the key fob lost synchronization with your Dodge Journey. In some cases, the act of replacing the battery can disrupt the connection. Unfortunately, for Dodge Journey models, reprogramming the key fob often requires professional equipment and isn’t typically a DIY task.
Another potential, though less likely immediately after a battery change, is a deeper electrical issue within your Dodge Journey. Problems with the car’s battery, even if recently replaced, or the vehicle’s immobilizer system could cause similar symptoms. The original poster in the forum mentioned trying to jump-start the car and replacing the car battery, which temporarily resolved the issue, suggesting a possible underlying electrical problem.
If you’ve checked the key fob battery, polarity, and even tried a new battery without success, and basic troubleshooting steps like trying any online “hacks” haven’t worked, it’s advisable to seek professional help. While a new key fob might be the answer in some scenarios, the “Key Fob Not Detected” message could indicate a more complex issue with your Dodge Journey’s electrical or security system. Consulting a certified mechanic or your Dodge dealership is the best course of action to accurately diagnose and resolve the problem, ensuring you’re not stranded with a non-functioning key fob.
