Even the most dependable vehicles require routine maintenance, and your Dodge key fob is no exception. One of the most common tasks is replacing the battery. Whether you’re experiencing a weak signal or simply want to be proactive, knowing how to open your Dodge key fob is a valuable skill. This guide will walk you through the process for different types of Dodge key fobs, making battery replacement a breeze.
For newer Dodge vehicles equipped with key fobs that don’t require dashboard insertion for operation, here’s how to open them:
-
Step 1: Locate the Lever and Release the Emergency Key. Turn your key fob over to find a small lever on the back. Slide this lever to the side. This action will release the mechanical emergency key. Pull the key out and set it aside in a safe place.
-
Step 2: Gather Your Tools. You’ll need a slim, flat object to gently pry open the fob. A flathead screwdriver is ideal, but a plastic trim removal tool or even a butter knife will work carefully.
-
Step 3: Pry Open the Fob Casing. Examine the bottom of the key fob, where you just removed the emergency key. You’ll notice a small slot or seam. This is where you need to insert your flat tool. Gently insert the tip of your screwdriver or chosen tool into this slot and carefully twist or pry. This action will begin to separate the two halves of the key fob. Work your tool around the seam if necessary, applying gentle pressure until the casing starts to split open.
-
Step 4: Access and Remove the Old Battery. Once the two halves of the key fob are separated, carefully pull them apart to reveal the internal components and the battery. Observe the battery’s orientation before removal, noting which side is facing up (usually indicated by “+” signs). Use your flat tool again to gently slide the battery out of its housing.
-
Step 5: Install the New Battery. The standard replacement battery for most Dodge key fobs is a CR2032. You can find these batteries at most auto parts stores, drugstores, and online retailers. Take your new CR2032 battery and slide it into the battery housing, ensuring the “+” side is facing the correct direction, matching the orientation of the old battery or the markings in the housing.
-
Step 6: Reassemble Your Key Fob. Take the other half of the key fob casing and carefully align it with the half containing the battery and electronics. Press the two halves firmly together until they click securely back into place. Finally, slide the emergency key back into its slot until it clicks and locks. Your modern Dodge key fob is now open, battery replaced, and ready to use!
For older Dodge vehicles that utilize key fobs which require insertion into the dashboard to start the vehicle, the process to open them is slightly different:
-
Step 1: Release the Emergency Key. Just like with the modern fob, start by sliding the lever on the back of the key fob to release and remove the emergency key. Set it aside.
-
Step 2: Locate and Remove the Phillips Head Screw. Flip the key fob so the buttons are facing down and the rounded end is pointing upwards. Look closely at the back of the fob; you’ll see a tiny Phillips head screw. You’ll need a small Phillips head screwdriver to remove this screw. Carefully unscrew and remove it, placing it in a safe spot so you don’t lose it.
-
Step 3: Separate the Fob Halves. With the screw removed, you can now use a flat-sided object, like a flathead screwdriver or plastic pry tool, to separate the two halves of the key fob casing. Insert your tool into the seam where the two halves meet and gently pry them apart.
-
Step 4: Access and Replace the Battery. Once open, you’ll see the inner workings of the fob. Carefully lift out the inner piece and flip it over to access the battery compartment. Again, take note of the battery’s orientation. Use your flat tool to slide the old battery out. Replace it with a new CR2032 battery, ensuring correct polarity.
-
Step 5: Reassemble the Key Fob. Carefully put the inner piece back into the fob casing, aligning it correctly. Then, bring the two halves of the key fob back together and press them firmly until they snap shut.
-
Step 6: Reinstall the Screw and Emergency Key. Replace the tiny Phillips head screw and tighten it gently but securely. Finally, slide the emergency key back into its designated slot until it clicks into place. Your older Dodge key fob is now opened, battery replaced, and ready for operation.
Changing your Dodge key fob battery is a straightforward task you can easily accomplish at home with a few simple tools. By following these steps, you can ensure your key fob remains functional and reliable, keeping you on the road without interruption.
