Experiencing a “Key Fob Not Detected” message in your 2017 Dodge Journey can be frustrating, especially when you rely on your vehicle daily. Many owners face this issue even after replacing their key fob battery, leading to confusion and concern about more significant problems. If you’re in this situation, understanding the potential causes and troubleshooting steps can help you diagnose the problem and find a solution.
One of the first things to consider, even after replacement, is the key fob battery itself. Ensure you’ve used the correct type of battery for your 2017 Dodge Journey key fob. Refer to your owner’s manual to confirm the exact battery specification. Sometimes, even new batteries can be faulty, so it’s worth double-checking the voltage if you have a multimeter. Also, make sure the battery is installed correctly, with the positive and negative terminals aligned properly within the key fob casing.
If the battery isn’t the issue, consider other potential culprits. A low car battery can sometimes cause communication problems between the key fob and the vehicle’s system. While you mentioned replacing your car battery, it’s still a good idea to ensure it’s properly charged and functioning correctly. Another key fob issue could be simple signal interference. External factors can sometimes disrupt the signal between your key fob and your Dodge Journey. Try starting your car in a different location to rule out potential interference.
Sometimes, the issue might not be with the key fob itself, but with the vehicle’s receiver. The Wireless Ignition Node (WIN) module, also known as the keyless entry module, is responsible for recognizing the signal from your key fob. If this module is malfunctioning, it may fail to detect your key fob, even with a fresh battery. Issues with the WIN module or the vehicle’s computer system often require professional diagnosis.
For troubleshooting, try using your spare key fob if you have one. If the spare key fob works, then the original key fob might be faulty or need reprogramming. If neither key fob works, the problem is likely with the car’s system, potentially the WIN module or the vehicle’s battery connections. In such cases, seeking assistance from a qualified mechanic or your Dodge dealership is advisable. They have diagnostic tools to pinpoint the exact cause and perform necessary repairs or reprogramming. While a key fob battery issue is a common starting point, a “Key Fob Not Detected” message on your 2017 Dodge Journey can stem from various sources, requiring systematic troubleshooting to resolve.
