Just like any battery-operated device, your Dodge key fob relies on a small battery to send signals to your vehicle. When this battery starts to weaken, you might notice your key fob becoming less responsive, requiring you to be closer to your car to lock, unlock, or start it remotely. Fortunately, changing the battery in your Dodge key fob is a straightforward process you can easily do yourself. As automotive experts at keyfobprog.com, we’re here to guide you through it, saving you a trip to the dealership and keeping your key fob working perfectly.
This guide will walk you through the steps to replace your Dodge key fob battery for two common types of fobs: those with and without a dashboard slot. The good news is, both are simple DIY tasks that require minimal tools and time.
Replacing the Battery in a Modern Dodge Key Fob (No Dashboard Slot)
If your Dodge key fob doesn’t need to be inserted into the dashboard to start your car, this section is for you. These newer style fobs are designed to be sleek and convenient, and battery replacement is just as user-friendly.
Step 1: Release and Remove the Emergency Key
Locate the small lever or button on the back or side of your key fob. Slide or press this release mechanism to detach the emergency key. Pull the key straight out and set it aside in a safe place. This key will be helpful in the next step and as a backup in general.
Step 2: Gather Your Tools
For this process, you’ll need a flat, thin tool to gently pry open the key fob casing. A small flathead screwdriver is ideal, but a plastic trim removal tool or even a sturdy guitar pick can also work. Avoid using anything too sharp that could scratch or damage the fob.
Step 3: Pry Open the Key Fob Casing
Examine the bottom of your key fob, where the emergency key was just removed. You should see a small slot or seam. This is where you’ll insert your flat tool. Carefully insert the tip of your screwdriver or chosen tool into this slot. Gently twist or pry to separate the two halves of the key fob casing. Take your time and apply steady, even pressure to avoid breaking the plastic.
Step 4: Access and Remove the Old Battery
Once the two halves of the fob are separated, you’ll see the internal electronics and the battery. The battery is usually a small, round, silver disc. Take note of how the battery is positioned in its housing, paying attention to the positive (+) and negative (-) sides. Often, there are “+” markings on the battery housing to guide you. Use your flat tool again to gently slide the old battery out of its compartment.
Step 5: Install the New Battery
The most common battery type for Dodge key fobs is the CR2032. You can usually find these at most auto parts stores, drugstores, and online retailers. Make sure you have the correct replacement battery before proceeding. Take your new CR2032 battery and slide it into the battery compartment, ensuring the polarity matches the original battery’s orientation (positive side up, if that was the original configuration – use the “+” markings as a guide).
Step 6: Reassemble the Key Fob
Carefully align the two halves of the key fob casing and press them firmly back together until they click securely into place. Ensure there are no gaps and the casing is fully closed. Finally, slide the emergency key back into its slot until it clicks and locks.
Replacing the Battery in an Older Dodge Key Fob (Dashboard Slot Style)
For older Dodge vehicles that require the key fob to be inserted into the dashboard to start the ignition, the process is slightly different but still manageable at home.
Step 1: Release and Remove the Emergency Key (Again!)
Just like with the modern fob, start by releasing and removing the emergency key. This step is consistent across most Dodge key fob models. Locate the release lever, detach the key, and set it aside.
Step 2: Locate and Remove the Phillips Head Screw
Flip the key fob over so the buttons are facing down and the rounded end is pointing upwards. Look closely at the back of the fob. You should see a tiny Phillips head screw. You’ll need a small Phillips head screwdriver to remove this screw. Turn it counterclockwise until it’s completely removed and store it in a safe place so you don’t lose it.
Step 3: Separate the Key Fob Halves
With the screw removed, you can now separate the two halves of the key fob casing. Use your flat tool (flathead screwdriver or plastic pry tool) to gently pry along the seam of the fob, similar to the modern fob style. The casing should separate relatively easily after the screw is removed.
Step 4: Access and Replace the Battery
Once open, you’ll see the inner workings of the key fob. Carefully lift out the inner piece to access the battery compartment, which is usually on the underside of this inner section. Again, note the battery orientation. Use your flat tool to slide out the old battery. Replace it with a new CR2032 battery, ensuring the correct polarity.
Step 5: Reassemble and Secure
Carefully place the inner piece back into the fob casing, aligning it correctly. Close the two halves of the fob and press them together. Now, reinsert the tiny Phillips head screw and tighten it clockwise until it is snug but not overtightened. Finally, slide the emergency key back into its designated slot.
Troubleshooting and Tips for Dodge Key Fob Battery Changes
- Key Fob Still Not Working? If your key fob doesn’t work after a battery replacement, double-check that you installed the battery with the correct polarity. Also, ensure the battery is brand new and not expired. If issues persist, you may need to consult your Dodge owner’s manual for key fob reprogramming instructions or seek professional assistance.
- Battery Type Confirmation: While CR2032 is common, always verify the correct battery type for your specific Dodge key fob. Check your owner’s manual or the markings on the old battery itself.
- Battery Disposal: Dispose of old batteries responsibly according to local regulations for electronic waste.
- Preventive Maintenance: Key fob batteries typically last for a few years. If you notice decreased range or responsiveness, it’s a good time to consider a battery change proactively.
Changing your Dodge key fob battery is a simple maintenance task that can save you time and money.
