Key fobs are essential for modern vehicles, providing convenient access and security features. However, like any electronic device, the battery in your Dodge key fob will eventually need replacing. Knowing how to open your Dodge key fob is a simple yet valuable skill that can save you time and a trip to the dealership. This guide provides comprehensive, easy-to-follow instructions for opening both modern and older style Dodge key fobs, ensuring you can confidently handle this routine maintenance task yourself.
Tools You’ll Need
Before you begin, gather these simple tools to make the process smooth and efficient:
- Emergency Key: This is integrated into your Dodge key fob and is essential for initiating the opening process.
- Flathead Screwdriver or Pry Tool: A small flathead screwdriver is ideal for gently prying open the key fob casing. A plastic pry tool can also be used to minimize the risk of scratching.
- Phillips Head Screwdriver (for older models): Some older Dodge key fobs utilize a small Phillips head screw to secure the casing.
- New CR2032 Battery: This is the standard battery type for most Dodge key fobs. You can find these at most auto parts stores, pharmacies, and online retailers.
Opening a Modern Dodge Key Fob (Non-Dashboard)
This type of key fob is common in newer Dodge models and does not require insertion into the dashboard to start the vehicle. Here’s how to open it:
Step 1: Remove the Emergency Key
Locate the release lever or button on the back or bottom of your Dodge key fob. Slide or press this lever to release the emergency key. Pull the key straight out and set it aside in a safe place.
Step 2: Prepare Your Tool
Take your flathead screwdriver or pry tool. Ensure it’s a size that will fit into the key fob’s seam without causing damage.
Step 3: Pry Open the Fob
Examine the key fob closely, specifically where the emergency key was just removed. You should see a small slot or seam. Insert the tip of your flathead screwdriver into this slot. Gently twist or pry to separate the two halves of the key fob casing. Work your way around the seam if necessary, applying gentle pressure until the case begins to split open.
Step 4: Battery Replacement
Once the key fob is open, carefully separate the two halves to expose the internal components and the battery. You’ll see the battery housed within a small compartment. Take note of the battery’s orientation, specifically the position of the positive (+) side. Use your flathead screwdriver or pry tool to gently slide the old battery out of its housing. Insert the new CR2032 battery, ensuring the positive (+) side is facing the correct direction, matching the orientation of the old battery or indicated markings in the battery compartment.
Step 5: Reassemble the 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 case is fully closed. Finally, slide the emergency key back into its slot until it clicks and locks.

Opening an Older Dodge Key Fob (Dashboard Style)
Some older Dodge vehicles utilize a key fob that needs to be inserted into the dashboard to start the ignition. While the process is similar, there’s an additional step involving a screw. Here’s how to open this type of Dodge key fob:
Step 1: Remove the Emergency Key
Just like the modern fob, start by removing the emergency key. Locate the release lever and detach the emergency key as described in Step 1 for the modern key fob.
Step 2: Locate and Remove the Screw
Flip the key fob over so the buttons are facing away from you. Examine the back casing, and you should find a small Phillips head screw, typically located near the top or center of the fob. Use a small Phillips head screwdriver to carefully remove this screw. Keep the screw in a safe place to avoid losing it.
Step 3: Pry Open the Fob
With the screw removed, you can now proceed to pry open the casing. Use your flathead screwdriver or pry tool and insert it into the seam of the key fob, similar to Step 3 for the modern fob. Gently twist or pry to separate the two halves of the casing.
Step 4: Access and Replace the Battery
Once open, you’ll see the internal components. In some older models, there might be an inner piece that needs to be lifted out to access the battery compartment. Carefully lift out this inner component if present, and then flip it over to reveal the battery. Use your tool to slide out the old battery, noting its orientation. Insert the new CR2032 battery with the positive (+) side in the correct position.
Step 5: Reassemble the Fob
Carefully reassemble the key fob. If there was an inner piece, place it back into the casing. Align the two halves of the outer casing and press them together until they snap shut. Replace the Phillips head screw and tighten it gently, being careful not to overtighten. Finally, reinsert the emergency key into its slot until it locks securely.
