Key fobs are an indispensable part of modern vehicle ownership, offering convenience and security. However, like any battery-powered device, the battery in your Dodge key fob will eventually need replacing. Knowing how to replace your Dodge key fob battery yourself can save you time and money. This guide provides comprehensive, easy-to-follow instructions for replacing the battery in both modern and older Dodge key fobs.
Whether you drive a recent model or a slightly older Dodge, the process is straightforward and requires minimal tools. Let’s dive into the simple steps to get your key fob working like new again.
Replacing the Battery in a Modern Dodge Key Fob
If your Dodge key fob is the type that doesn’t require insertion into the dashboard to start the vehicle, follow these steps:
Step 1: Release and Remove the Emergency Key
Locate the lever on the back of your key fob. Slide this lever to release the emergency key. Once released, carefully remove the emergency key and set it aside in a safe place.
Step 2: Prepare a Flat-Sided Tool
You’ll need a flat, thin tool to gently pry open the key fob. A flathead screwdriver is ideal for this task. Ensure the screwdriver is not too large to avoid damaging the fob casing.
Step 3: Pry Open the Key Fob Casing
Examine the bottom of the key fob, specifically where the emergency key was housed. You’ll notice a small slot or seam. This is where you need to insert your flathead screwdriver or chosen tool. Gently insert the tool into the slot and carefully pry the two halves of the key fob apart. Avoid using excessive force, as you only need to separate the two pieces enough to access the battery compartment.
Step 4: Access and Remove the Old Battery
Once the key fob is open, you’ll see the internal electronics and the battery. The battery is typically housed in a small compartment. Use your flat tool again to carefully slide the old battery out of its housing. Pay close attention to the orientation of the battery, noting which side is facing up (usually indicated by “+” signs). This is crucial for correct installation of the new battery.
Step 5: Install the New Battery
The standard replacement battery for most Dodge key fobs is a CR2032 battery. These batteries are widely available at auto parts stores, drugstores, and online retailers. Take your new CR2032 battery and slide it into the battery compartment, ensuring it’s oriented the same way as the old battery (match the “+” signs).
Step 6: Reassemble the Key Fob
Take 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 fob feels properly sealed. Finally, re-insert the emergency key back into its slot until it clicks and locks.
Replacing the Battery in an Older Dodge Key Fob
For older Dodge vehicles that use a key fob which needs to be inserted into the dashboard to start the car, the battery replacement process is slightly different:
Step 1: Release the Emergency Key
Similar to the modern key fob, start by sliding the release lever on the back of the fob to detach and remove the emergency key. Set the key aside safely.
Step 2: Locate and Remove the Phillips Head Screw
Flip the key fob so the buttons are facing away from you and the rounded end is pointing upwards. Look closely at the back of the fob; you should 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 secure spot so you don’t lose it.
Step 3: Separate the Key Fob Halves
With the screw removed, you can now use a flat-sided tool, like a flathead screwdriver, to gently separate the two halves of the key fob. Insert the tool into the seam where the two halves join and carefully pry them apart.
Step 4: Access and Replace the Battery
Once opened, you’ll see the inner workings of the fob. Carefully lift out the inner piece and flip it over to access the battery compartment. Use your flat tool to slide out the old battery, again noting its orientation for correct replacement.
Step 5: Install the New Battery (CR2032)
Insert a new CR2032 battery into the compartment, ensuring it’s placed in the same orientation as the old one.
Step 6: Reassemble the Key Fob
Carefully put the three pieces of the key fob back together – the two halves of the casing and the inner electronic piece. Ensure they fit snugly. Replace the Phillips head screw and tighten it gently but securely. Finally, slide the emergency key back into its place until it clicks.
By following these steps, you can easily replace the battery in your Dodge key fob, regardless of whether you have a modern or older model. This simple maintenance task can save you a trip to the dealership and keep your key fob functioning perfectly.
