Just like any component of your vehicle, your Dodge key fob, while durable, requires routine maintenance. One of the most common tasks is replacing the battery. If your key fob is starting to act erratically or has stopped working altogether, it’s likely time for a new battery. As your trusted automotive experts at keyfobx.com, we’re here to guide you through the straightforward process of opening your Dodge key fob and replacing its battery. No need for a mechanic; you can easily do this yourself at home in just a few minutes.
Tools You’ll Need for a Dodge Key Fob Battery Replacement
Before we begin, gather these simple tools to make the process smooth and efficient:
- New CR2032 Battery: This is the standard battery type for most Dodge key fobs and readily available at auto parts stores, pharmacies, and online retailers.
- Small Flathead Screwdriver: This will be your primary tool for gently prying open the key fob casing.
- Small Phillips Head Screwdriver (For Older Fobs): Some older Dodge key fob models might have a small screw securing the case.
How to Open a Modern Dodge Key Fob (No Dashboard Slot)
This guide applies to Dodge key fobs that do not require insertion into the dashboard to start the vehicle. Follow these steps:
Step 1: Release and Remove the Emergency Key
Locate the small lever or button on the back or side of your Dodge key fob. Slide or press this release to detach the mechanical emergency key. Pull the key out and set it aside in a safe place. This key is a backup to manually unlock your car door if needed.
Step 2: Prepare Your Flathead Screwdriver
Take your small flathead screwdriver. You’ll use this tool carefully to separate the two halves of the key fob casing. Ensure you have a firm and comfortable grip on the screwdriver.
Step 3: Gently Pry Open the Key Fob Casing
Examine the key fob where the emergency key was just removed. You will notice a small slot or seam. This is your insertion point. Carefully insert the tip of your flathead screwdriver into this slot. Apply gentle but firm pressure to pry the two halves of the key fob apart. Work your way around the seam if necessary, gently twisting the screwdriver to separate the casing. Avoid using excessive force to prevent damage to the plastic.
Step 4: Access and Replace the Key Fob Battery
Once the key fob is open, you’ll see the internal components and the battery. The battery is typically a round, coin-shaped CR2032 battery. Note the orientation of the battery before removing it, paying attention to the positive (+) side. You can use your flathead screwdriver or your fingernail to gently slide the old battery out of its housing. Take your new CR2032 battery and slide it into the battery compartment, ensuring the positive (+) side is facing the correct direction (usually upwards – match the orientation of the old battery or look for “+” markings in the housing).
Step 5: Reassemble Your Dodge Key Fob
Carefully align the two halves of the key fob casing back together. Press them firmly until they snap securely back into place. You should hear a click, indicating that the fob is properly closed. Finally, slide the emergency key back into its slot until it clicks and locks into position.
How to Open an Older Dodge Key Fob (Dashboard Slot)
If you have an older Dodge vehicle where the key fob needs to be inserted into the dashboard to start the car, the process is slightly different due to a screw holding the case together. Here’s how to open it:
Step 1: Remove the Emergency Key
Just as with the modern fob, begin by removing the emergency key. Locate the release lever or button, activate it, and slide out the emergency key. 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 top is pointing upwards. Look closely at the back of the fob; you should find a tiny Phillips head screw. Use your small Phillips head screwdriver to carefully unscrew and remove this screw. Keep the screw in a safe place so you don’t lose it, perhaps placing it with the emergency key.
Step 3: Pry Open the Key Fob Casing
With the screw removed, you can now proceed to separate the two halves of the fob. Use your flathead screwdriver again, inserting it into the seam, often located where the emergency key was or along the sides of the fob. Gently pry and twist to separate the casing, working your way around the seam as needed.
Step 4: Replace the Battery in the Older Dodge Key Fob
Once open, you’ll see the internal components. You might need to lift out an inner piece to fully access the battery compartment. Identify the CR2032 battery and note its orientation. Use your flathead screwdriver or fingernail to carefully remove the old battery. Insert the new CR2032 battery, ensuring correct polarity (positive side up or matching the markings).
Step 5: Reassemble the Older Dodge Key Fob
Carefully put all the pieces back together. If there was an inner piece you removed, make sure it’s correctly placed. Align the two main halves of the key fob casing and press them together until they snap shut. Replace the small Phillips head screw and tighten it gently but firmly to secure the case. Finally, slide the emergency key back into its slot.
