Experiencing issues with your Dodge Journey after replacing the key fob battery? It’s a common frustration when that “Key Fob Not Detected” message pops up on your dashboard, especially after what should be a simple battery replacement. You’ve swapped out the old battery, expecting everything to work seamlessly, but instead, you’re met with a vehicle that refuses to start, and keyless entry that’s suddenly unresponsive. This situation can be particularly stressful, especially for independent individuals relying on their vehicle daily.
It’s understandable to feel confused when your Dodge Journey won’t recognize the key fob after a battery change. You might be thinking, “Could it really be more than just a battery issue?” The good news is, often it’s something straightforward. Let’s explore some potential causes and troubleshooting steps to get you back on the road without breaking the bank.
One of the first things to consider is the battery itself. While you’ve replaced it, ensure you’ve used the correct type of battery for your Dodge Journey key fob. Refer to your owner’s manual for the specific battery type. It’s also worth double-checking the battery orientation within the fob casing. Sometimes, incorrect polarity can prevent the fob from functioning correctly. Even a brand new battery can occasionally be faulty, so if possible, trying a different new battery is a simple step to rule out a battery issue entirely.

Beyond the battery itself, there are other potential culprits. While less common after a simple battery change, the key fob’s internal circuitry could be malfunctioning. If you have a spare key fob, try using it. If the spare works, this could indicate an issue with the primary fob, possibly requiring professional key fob programming or even a replacement.
Another factor, although mentioned as recently replaced in the original scenario, is the car battery. Dodge Journeys, like many modern vehicles, are sensitive to voltage fluctuations. A weak car battery, even a relatively new one, can sometimes cause unexpected electronic issues, including key fob recognition problems. While you’ve replaced the car battery, ensure the connections are clean and tight. If the issue persists, having the car battery voltage tested by an auto parts store or mechanic can provide further insights.
In some cases, the issue might lie within the vehicle’s keyless entry system receiver. This is less likely to be triggered by a key fob battery replacement but is still a possibility. If none of the troubleshooting steps above resolve the “Key Fob Not Detected” message, a professional diagnostic scan by a qualified mechanic or dealership technician may be necessary to pinpoint the exact cause, whether it’s a key fob problem, receiver issue, or another underlying electronic fault in your Dodge Journey.
Dealing with car troubles can be stressful and costly. By systematically checking these potential issues, starting with the simplest – the key fob battery and its installation – you can often resolve the “Key Fob Not Detected” problem yourself or at least gather valuable information before seeking professional assistance.
