Experiencing the dreaded “Key Fob Not Detected” message on your 2016 Dodge Journey can be incredibly frustrating, especially after you’ve just replaced the key fob battery. It’s a common issue that can leave you stranded, but often, the solution is simpler than you might think. Let’s explore the potential causes and how you can get back on the road.
One of the first things you might consider, especially if you’ve recently seen a “low key fob battery” warning, is the battery itself. While you’ve already replaced it, it’s worth double-checking a few things. Ensure you used the correct type of battery – most Dodge key fobs use a CR2032 battery. Also, make sure the battery is installed correctly, paying attention to the polarity (+ and – sides). Sometimes, a new battery can be faulty, so if you have another new battery, try swapping it out just to rule out a defective battery.
If the battery isn’t the culprit, the issue could lie in the key fob’s programming. Sometimes, after a battery change, the key fob might lose synchronization with your Dodge Journey. While less common on newer models, it’s a possibility. Refer to your owner’s manual for any key fob reprogramming instructions. Some vehicles have a specific sequence involving the ignition and door locks that can re-sync the key fob. If your owner’s manual doesn’t provide a DIY method, don’t worry, there are still other avenues to explore.
Another potential, though less frequent, cause could be related to your vehicle’s battery. You mentioned replacing your car battery, which is a good step, but it’s important to ensure the new battery is fully charged and functioning correctly. A weak car battery can sometimes cause electronic system glitches, including key fob recognition problems. Have your car battery tested to ensure it’s providing the necessary voltage.
If you’ve exhausted these basic checks and are still facing the “Key Fob Not Detected” message, there could be a more technical issue at play. The key fob itself could be faulty, or there might be a problem with the receiver in your Dodge Journey that detects the key fob signal. In these situations, it’s advisable to seek professional help.
Consider contacting a certified mechanic or your local Dodge dealership. They have specialized diagnostic tools that can pinpoint the exact cause of the problem, whether it’s a faulty key fob, a receiver issue in your vehicle, or a more complex electronic problem. An automotive locksmith is another excellent resource, especially for key fob related issues. They often have the equipment to test and reprogram key fobs, and in some cases, can diagnose receiver problems as well. While it might involve a cost, professional diagnosis can save you time and further frustration by accurately identifying and resolving the root cause of your 2016 Dodge Journey key fob issue.
