Just like any battery-operated device, the battery in your Dodge key fob will eventually need replacing. A dead or dying key fob battery can be a real inconvenience, preventing you from remotely locking or unlocking your doors, or even starting your vehicle in some cases. Fortunately, changing the battery in your Dodge key fob is a straightforward process you can easily do yourself at home. This guide will walk you through the steps for both modern and older style Dodge key fobs, ensuring you get back to hassle-free vehicle access in no time.
Tools You’ll Need
Before you begin, gather these simple tools:
- New Battery: You’ll most likely need a CR2032 battery. Check your owner’s manual or the old battery itself to confirm the exact type. These batteries are commonly available at most drugstores, supermarkets, and auto parts stores.
- Small Flathead Screwdriver: This will be used to gently pry open the key fob casing. A small, precision screwdriver is ideal.
- Phillips Head Screwdriver (for older models): Some older Dodge key fobs use a small Phillips head screw to secure the casing.
- Soft Cloth (optional): To protect the key fob surface from scratches while prying it open.
Step-by-Step Guide for Modern Dodge Key Fobs
This procedure applies to Dodge key fobs that do not require insertion into the dashboard to start the vehicle.
Step 1: Release the Emergency Key
Locate the small lever or button on the back or side of your key fob. Slide or press it to release the mechanical emergency key. Pull the key out and set it aside.

Step 2: Prepare Your Tools
Ensure you have your flathead screwdriver ready. If you have a soft cloth, you can wrap the tip of the screwdriver to minimize any potential scratches on the key fob casing.
Step 3: Pry Open the Key Fob
Examine the bottom of the key fob, where the emergency key was just removed. You should see a small slot or seam. This is where you need to insert the flathead screwdriver. Gently twist or pry to separate the two halves of the key fob. Work your way around the seam, if necessary, until the case begins to split open.

Step 4: Replace the Old Battery
Once the fob is open, you’ll see the internal electronics and the battery. Note the orientation of the battery (+ side up or down) before removing it. Use the flathead screwdriver or your fingernail to gently slide the old battery out of its housing.

Step 5: Install the New Battery
Take your new CR2032 battery and slide it into the battery compartment, ensuring the correct orientation (matching the + signs if visible, or as you noted in the previous step).
Step 6: Reassemble Your Key Fob
Carefully align the two halves of the key fob casing and press them firmly back together until they click securely. Ensure there are no gaps. Finally, slide the emergency key back into its slot until it clicks into place.
Step-by-Step Guide for Older Dodge Key Fobs
This procedure is for older Dodge vehicles that use key fobs which may require insertion into the ignition or dashboard.
Step 1: Release the Emergency Key
Just like with the modern fob, start by releasing and removing the emergency key. Locate the release mechanism and slide out the key.
Step 2: Locate and Remove the Screw
Flip the key fob over so the buttons are facing down. Look for a small Phillips head screw, usually located on the back of the fob. Use your Phillips head screwdriver to carefully remove this screw and set it aside in a safe place.
Step 3: Pry Open the Key Fob
With the screw removed, you can now pry open the fob. Use your flathead screwdriver to gently separate the two halves of the casing, similar to the modern fob procedure. Insert the screwdriver into the seam and gently twist until the case begins to open.
Step 4: Access and Replace the Battery
Once open, you might see an inner piece holding the electronics. Carefully lift this inner piece out and flip it over to access the battery compartment. Remove the old battery, noting its orientation.
Step 5: Install the New Battery
Insert the new CR2032 battery into the compartment, ensuring it’s oriented correctly.
Step 6: Reassemble Your Key Fob
Place the inner piece (if applicable) back into the fob casing. Carefully align the two halves of the fob and press them together until they snap shut. Replace the Phillips head screw and tighten it gently but securely. Finally, reinsert the emergency key.
You’re All Set!
Changing the battery in your Dodge key fob is a simple maintenance task that can save you time and frustration.
