Experiencing a “Key Fob Not Detected” message on your Dodge Journey can be frustrating, especially when you rely on your vehicle daily. It’s a common issue that many Dodge Journey owners face, and while a low key fob battery is often the first suspect, the problem could stem from other sources. Let’s explore the potential causes and troubleshooting steps, focusing on the Battery For Dodge Journey 2015 Key Fob and related issues.
When your Dodge Journey displays “Key Fob Not Detected,” it means the vehicle’s system isn’t recognizing the signal from your key fob. This can prevent you from starting your car, using keyless entry, and even locking or unlocking your doors remotely. You might have recently encountered this problem after changing your key fob battery, leaving you puzzled about the root cause.
Several factors can lead to this error message. While we’ll delve into the battery for dodge journey 2015 key fob, it’s crucial to consider other potential culprits:
- Key Fob Battery Issues: Although you might have replaced the battery, it’s worth double-checking. Ensure you’ve used the correct type of battery (typically a CR2032 battery for Dodge Journey key fobs) and that it’s installed correctly with the right polarity. A weak or incompatible battery, even a new one, can sometimes cause detection problems.
- Car Battery Problems: A weak car battery can also lead to various electrical issues, including key fob detection failures. Modern car systems are interconnected, and low voltage can affect the receiver that detects the key fob signal.
- Key Fob Programming or Synchronization: Sometimes, the key fob might lose synchronization with the vehicle’s system. This can happen due to various electrical glitches or after battery replacements in some cases.
- Radio Frequency (RF) Interference: Strong radio signals from other devices can occasionally interfere with the key fob signal, although this is less common.
- Receiver Issues in the Vehicle: The problem might lie within the vehicle’s receiver module, which is responsible for detecting the key fob signal. This could be related to the Remote Frequency Hub (RF Hub) or the Totally Integrated Power Module (TIPM) in your Dodge Journey.
Here are some troubleshooting steps you can try to resolve the “Key Fob Not Detected” issue:
-
Verify Key Fob Battery: Open your key fob and double-check the battery. Ensure it’s the correct type (CR2032), properly installed, and not defective. Consider trying another new battery from a different batch to rule out a faulty battery.

Try the Key Fob Emergency Start Procedure: Refer to your Dodge Journey owner’s manual for the emergency starting procedure when the key fob is not detected. This usually involves placing the key fob in a specific location, such as under the steering column or near the start button, to allow the vehicle to detect it for starting.
-
Check Your Car Battery: Ensure your car battery is properly charged and in good condition. If it’s old or weak, consider getting it tested or replaced. A healthy car battery is crucial for the proper functioning of all electrical systems, including keyless entry and key fob detection.
-
Check for RF Interference: Rule out potential RF interference by moving away from any strong electronic devices or areas with potential signal interference and trying to start your car again.
-
Consider Key Fob Programming: If you suspect key fob desynchronization, you might need to reprogram or resynchronize your key fob with your Dodge Journey. This process can sometimes be done at home using specific procedures outlined in your owner’s manual, or it might require professional programming at a dealership or locksmith.
If these steps don’t resolve the “Key Fob Not Detected” issue, it’s advisable to seek professional diagnosis. A qualified mechanic or Dodge dealership technician can use specialized tools to diagnose the underlying problem, which could be related to the vehicle’s receiver module (RF Hub or TIPM) or other electrical system faults. While addressing the battery for dodge journey 2015 key fob is a crucial first step, a thorough diagnosis is essential to pinpoint and fix the root cause of the problem and get you back on the road.
