Experiencing trouble with your 2016 Dodge Journey key fob can be frustrating, especially when you’re facing the dreaded “Key Fob Not Detected” message. It’s a common issue that many Dodge owners encounter, and while a low battery is often the culprit, sometimes the problem can be a bit more complex. Let’s explore some troubleshooting steps to get you back on the road.
One of the first signs of a weakening key fob battery in your Dodge Journey is the appearance of a “Low Key Fob Battery” message on your dashboard. If you’ve already replaced the battery in your key fob, but are still facing issues like the “Key Fob Not Detected” message, along with symptoms such as the inability to start your car, or keyless entry malfunctions, it’s time to investigate further. You might find that even though the buttons on your key fob still lock and unlock the doors or activate the panic button, the car itself isn’t recognizing the fob’s presence for starting or accessory functions.
If you’ve recently replaced your Dodge Journey key fob battery and are still encountering problems, consider these potential solutions:
-
Check Your Car Battery: While seemingly unrelated to the key fob battery, a weak car battery can sometimes cause unusual electronic issues, including key fob detection problems. While you mentioned replacing your car battery, ensure it’s properly installed and sufficiently charged. A voltage drop during starting could potentially interfere with the key fob system’s recognition.
-
Key Fob Reprogramming: In some instances, after a battery change or electrical system disruption, your key fob might need to be reprogrammed to your Dodge Journey. While some online resources suggest DIY reprogramming methods, these are not always reliable for modern vehicles like the 2016 Dodge Journey. Dealerships possess specialized tools to accurately reprogram key fobs.
-
Signal Interference: Although less likely, external radio frequency interference could theoretically disrupt the signal between your key fob and your vehicle, especially in areas with strong electromagnetic fields. Try starting your car in a different location to rule out this improbable cause.
-
Key Fob Malfunction: It’s possible that the issue isn’t the battery, but rather a malfunction within the key fob itself. Internal damage from drops, moisture, or general wear and tear can lead to signal transmission failures. Testing with a spare key fob, if available, can help determine if the problem lies with the fob itself.
If none of these basic troubleshooting steps resolve the “Key Fob Not Detected” issue on your 2016 Dodge Journey, it’s advisable to seek professional assistance. Independent auto repair shops or your local Dodge dealership have diagnostic equipment that can pinpoint the exact cause of the problem, whether it’s a faulty key fob, a receiver issue in the car’s system, or another underlying electrical problem. Attempting further DIY fixes without proper diagnosis could potentially lead to more complex issues. For a reliable solution, professional diagnostics are usually the most efficient path to resolving your Dodge Journey key fob troubles.
