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 major inconvenience, preventing you from remotely unlocking your doors, setting off the panic alarm, or even starting your vehicle in some cases. Fortunately, changing the battery in a Dodge key fob is a simple task you can easily do yourself at home in just a few minutes. This guide will walk you through the process for both modern and older style Dodge key fobs, ensuring you can get back to using your remote without a trip to the dealership.
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 for the exact type. These batteries are widely available at drugstores, supermarkets, auto parts stores, and online.
- Small Flathead Screwdriver: This will be used to gently pry open the key fob casing.
- Small Phillips Head Screwdriver (For Older Fobs): Some older Dodge key fobs use a small screw to secure the casing.
Step-by-Step Guide for Modern Dodge Key Fobs
If your Dodge key fob is a more recent design and doesn’t require being inserted into the dashboard to start the car, follow these steps:
Step 1: Release the Emergency Key
Locate the small lever or button on the back or bottom of your key fob. Slide or press this release to detach the mechanical emergency key. Pull the key out and set it aside. This key can be used to manually unlock your car door if needed.
Step 2: Pry Open the Fob
Examine the fob where the emergency key was just removed. You’ll notice a small slot or seam. This is where you need to gently insert your flathead screwdriver. Carefully twist the screwdriver to pry the two halves of the key fob apart. Work your way around the seam, gently prying until the casing begins to separate. Avoid using excessive force to prevent damaging the plastic.
Step 3: Remove and Replace the Battery
Once the fob is open, you’ll see the internal electronics and the battery. Note the orientation of the battery before removing it – specifically, how the positive (+) side is facing. Use the flathead screwdriver or your fingernail to carefully slide the old battery out of its housing.
Now, take your new CR2032 battery and slide it into place, ensuring the positive (+) side is facing the same direction as the old battery was. If you’re unsure, look for “+” markings inside the battery compartment as a guide.
Step 4: Reassemble the Key Fob
Carefully align the two halves of the key fob casing and press them firmly back together until they snap securely. You should hear a click indicating they are properly closed. Finally, slide the emergency key back into its slot until it clicks into place.
Step-by-Step Guide for Older Dodge Key Fobs
For older Dodge vehicles that use a key fob which may need to be placed in the ignition or dashboard, the process is slightly different due to a securing screw:
Step 1: Release the Emergency Key and Locate Screw
Just as with the modern fob, start by releasing and removing the emergency key. After removing the key, flip the fob over so the buttons are facing down. Look for a tiny Phillips head screw, usually located on the back of the fob, often near the top rounded edge.
Step 2: Remove the Screw and Open the Fob
Use the small Phillips head screwdriver to carefully remove this screw. Keep the screw in a safe place so you don’t lose it. Once the screw is removed, you can proceed to pry open the fob. Use your flathead screwdriver to gently pry apart the two halves of the key fob casing, similar to the modern fob method. Insert the flathead screwdriver into the seam and gently twist to separate the halves.
Step 3: Access and Replace the Battery
After opening the fob, you may see an inner piece containing the electronics. Carefully lift this inner piece out and flip it over to access the battery compartment. Again, take note of the battery’s orientation before removal. Use the flathead screwdriver or your fingernail to slide out the old battery. Insert the new CR2032 battery, ensuring the positive (+) side is correctly oriented.
Step 4: Reassemble the Key Fob
Carefully place the inner electronic piece back into the fob casing, ensuring it sits correctly. Align the two halves of the key fob and press them together until they snap shut. Replace the Phillips head screw and tighten it gently, being careful not to overtighten. Finally, slide the emergency key back into its slot.
Once you’ve reassembled your key fob, test the buttons to ensure they are working correctly. If your Dodge key fob is still not working after replacing the battery, there might be another issue, and it’s best to consult your Dodge dealership or a qualified automotive technician. However, in most cases, these steps will successfully solve the problem and get your key fob working like new again.
