Is your 2012 Dodge Journey displaying a “Low Key Fob Battery” message, or worse, “Key Fob Not Detected”? Don’t worry, you’re not alone. Replacing the key fob battery in your Dodge Journey is a straightforward task you can easily handle yourself, saving time and money compared to dealership service. This guide will walk you through each step to ensure a smooth and successful battery replacement for your 2012 Dodge Journey key fob.
The key fob is crucial for modern vehicle convenience, controlling everything from remote locking and unlocking to starting your car. When the battery weakens, you might experience intermittent issues like reduced range or the dreaded “Key Fob Not Detected” error. While the original poster described issues with a 2016 model, the 2012 Dodge Journey Key Fob Battery Replacement process is quite similar and equally important to address promptly. Ignoring these warning signs can lead to unexpected lockouts or the inability to start your vehicle, situations no driver wants to face.
To replace your 2012 Dodge Journey key fob battery, you’ll need a few simple tools: a small flathead screwdriver (often a precision screwdriver works best), and a new CR2032 3V lithium coin battery – the standard for most Dodge key fobs. You can find these batteries at most drugstores, supermarkets, and auto parts stores.
Now, let’s get to the replacement process:
- Locate the notch on your key fob: On the back of your 2012 Dodge Journey key fob, you’ll find a small notch or slot. This is where you’ll insert the flathead screwdriver to open the case.
- Carefully pry open the case: Insert the tip of your flathead screwdriver into the notch. Gently twist the screwdriver to separate the two halves of the key fob case. Avoid using excessive force, as you could damage the plastic casing.
- Remove the old battery: Once the case is open, you’ll see the battery. Take note of the battery’s orientation (+ side up or down) before removing it. You can use your fingertip or the edge of the screwdriver to carefully pry out the old battery.
- Insert the new battery: Place the new CR2032 battery into the battery compartment, ensuring the correct polarity (match the + and – signs with the markings in the case). Usually, the positive (+) side faces upwards.
- Reassemble the key fob: Carefully snap the two halves of the key fob case back together. Ensure they are firmly closed and properly aligned. You should hear a click or feel them securely latching.
- Test your key fob: Press a button on your key fob to test if it’s working. The doors should lock or unlock, and the panic button should function. If your Dodge Journey was displaying a “Key Fob Not Detected” message, attempt to start your vehicle to confirm the issue is resolved.

In most cases, replacing the battery will solve key fob issues. However, if you continue to experience problems like “Key Fob Not Detected” even after a fresh battery replacement, there might be other underlying issues. These could include:
- Incorrect Battery Installation: Double-check that the battery is the correct CR2032 type and installed with the correct polarity.
- Key Fob Damage: If your key fob has been dropped or exposed to moisture, internal damage could be the cause.
- Vehicle Receiver Issues: In rare cases, the problem might lie within your Dodge Journey’s key fob receiver, requiring professional diagnosis.
- Key Fob Programming: While less common after a simple battery change, sometimes the key fob might need to be reprogrammed to your vehicle, especially if the battery was left out for an extended period.
If you’ve replaced the battery and are still facing “Key Fob Not Detected” or starting problems with your 2012 Dodge Journey, it’s advisable to consult a qualified automotive technician. They can diagnose whether the issue is with the key fob itself or a more complex vehicle system problem. While this guide focuses on battery replacement, understanding potential deeper issues is crucial for complete problem resolution. Remember to always use the correct battery type and handle your key fob with care to prolong its life and ensure reliable operation of your Dodge Journey.
