Experiencing issues with your Dodge Journey 2015 key fob can be incredibly frustrating, especially when it leaves you stranded. A common culprit is often the key fob battery. If you’re facing a “Key Fob Not Detected” message or struggling to start your vehicle, understanding the potential battery problems and troubleshooting steps is crucial. Let’s delve into diagnosing and resolving these key fob battery related issues in your Dodge Journey 2015.
One of the first signs of a weakening key fob battery is the “Low Key Fob Battery” warning displayed on your dashboard. Many Dodge Journey owners might promptly replace the battery at this stage, assuming it will resolve any problems. However, sometimes, even after a battery replacement, you might encounter persistent issues like the dreaded “Key Fob Not Detected” message. This can be perplexing and lead you to believe that the problem is more complex than just a simple battery swap.
If you’ve recently replaced your Dodge Journey 2015 Key Fob Battery and are still facing problems such as the car failing to start, not going into ACC or RUN mode, and keyless entry malfunctions, it’s time to investigate further. While a new battery seems like the obvious solution, there could be other factors at play. It’s important to note that even if the buttons on your key fob are working – allowing you to lock, unlock, or use the panic button – it doesn’t necessarily mean the battery is functioning correctly for all key fob operations, particularly the vehicle detection and starting sequence.
Let’s consider some troubleshooting steps to address this “Key Fob Not Detected” problem in your Dodge Journey 2015 after a battery replacement:
-
Verify Battery Type and Installation: Double-check that you have installed the correct type of battery for your Dodge Journey 2015 key fob. Refer to your owner’s manual for the specific battery type. Ensure the battery is inserted correctly, paying close attention to the polarity (+ and -) markings inside the battery compartment. Incorrect installation can prevent the key fob from working properly.
-
Check for Battery Contact Issues: Examine the metal contacts within the key fob battery compartment. Sometimes these contacts can become corroded, dirty, or bent, hindering proper electrical connection. Gently clean the contacts with a cotton swab and a bit of rubbing alcohol. Ensure they are making firm contact with the battery.
-
Resync or Reprogram the Key Fob (If Necessary): In some cases, after a battery change, the key fob might need to be resynchronized with your Dodge Journey. Consult your owner’s manual for any key fob reprogramming procedures specific to the 2015 model. While less common after a simple battery change, it’s a step worth considering. Dealerships can also assist with key fob programming if needed.
-
Consider a Faulty New Battery: Although you’ve installed a new battery, it’s possible the new battery itself is defective or has a low charge. Try using another new battery from a different batch or brand to rule out a faulty battery issue.
-
Evaluate Car Battery Health: While you mentioned replacing the car battery, it’s still worthwhile to ensure the car battery is in optimal condition. A weak car battery can sometimes cause unusual electronic issues, including key fob detection problems. Have your car battery tested to confirm it’s holding a proper charge.
-
Check for Key Fob Damage: Inspect your key fob for any signs of physical damage, such as cracks, water damage, or button malfunctions. If the key fob has been damaged, internal components might be affected, leading to communication problems with your vehicle.
If you have diligently gone through these troubleshooting steps and your Dodge Journey 2015 continues to display the “Key Fob Not Detected” message, and keyless entry remains non-functional, it might indicate a more complex issue. This could involve a problem with the key fob itself beyond just the battery, or a receiver issue within the vehicle’s security system.
In such situations, seeking professional assistance from a qualified mechanic or your local Dodge dealership is advisable. They possess specialized diagnostic tools to pinpoint the exact cause of the problem, whether it’s a faulty key fob, a receiver malfunction in your Dodge Journey, or another underlying electrical issue. While DIY troubleshooting is helpful, complex electronic issues often require expert intervention to ensure accurate diagnosis and effective repair. Addressing these issues promptly will get you back on the road with a reliably functioning key fob and a smoothly operating Dodge Journey 2015.
