Key fobs are incredibly convenient, allowing you to lock, unlock, and even start your Dodge vehicle with the push of a button. However, these devices rely on batteries, and eventually, you’ll find yourself needing to replace the battery in your Dodge key fob. Don’t worry, this is a simple task you can easily do yourself at home. This guide will walk you through the process for different types of Dodge key fobs, ensuring you can get back to using your remote without any hassle.
Tools You’ll Need
Before you begin, gather these simple tools:
- A new CR2032 battery – this is the most common type for Dodge key fobs and readily available at most auto parts stores, pharmacies, and online retailers.
- A small flathead screwdriver or a similar flat, thin tool to gently pry open the key fob casing.
- For some older key fobs, a small Phillips head screwdriver might be necessary.
Step-by-Step Guide for Modern Dodge Key Fobs
This method 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 bottom of your Dodge key fob. Slide or press this release to detach and remove the emergency key. Set the key aside in a safe place.
Step 2: Prepare Your Tool
Take your flathead screwdriver or prying tool. Ensure it’s a suitable size to fit into small crevices without causing damage to the plastic casing of your key fob.
Step 3: Carefully Pry Open the Fob
Examine the key fob, specifically looking at the area where you removed the emergency key. You should notice a small slot or seam. This is where you need to gently insert the flathead screwdriver. Apply gentle pressure and twist the screwdriver to carefully separate the two halves of the key fob. Work your way around the seam if necessary, being patient to avoid cracking the plastic.
Step 4: Battery Access and Removal
Once the key fob is open, you’ll see the internal electronics and the battery. The battery is usually a circular, silver CR2032 type. Take note of the battery’s orientation before removing it – observe which side is facing up (usually the positive side marked with a “+”). Use your 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 install it in the same orientation as the old one. Ensure the “+” side is facing the correct direction, matching the markings in the battery compartment or your memory of the old battery’s position. Push the new battery firmly into place until it’s securely seated.
Step 6: Reassemble the Key Fob
Carefully align the two halves of the key fob casing and press them firmly back together until they click shut. Ensure there are no gaps and the fob feels securely closed. Finally, slide the emergency key back into its slot until it clicks into place.
Step-by-Step Guide for Older Dodge Key Fobs
If your Dodge vehicle uses a key fob that needs to be inserted into the ignition or dashboard, the process is slightly different, often involving a small screw.
Step 1: Release the Emergency Key
Just like with modern fobs, the first step is to remove the emergency key. Locate the release lever and detach the key, setting it aside.
Step 2: Locate and Remove the Screw
Flip the key fob over so the buttons are facing away from you. Look at the back of the fob, typically near the top rounded end. You should see a tiny Phillips head screw. Use a small Phillips head screwdriver to carefully remove this screw and keep it in a safe place.
Step 3: Gently Pry Open the Fob
With the screw removed, you can now separate the two halves of the key fob. You might be able to pry them apart with your fingers, or you may need to use a flathead screwdriver to gently pry along the seam, similar to the modern key fob method.
Step 4: Access and Remove the Battery
Once open, you’ll likely see an inner component containing the electronics and battery. Carefully lift this inner piece out of the fob casing and flip it over to access the battery compartment. Remove the old CR2032 battery, noting its orientation.
Step 5: Install the New Battery
Insert the new CR2032 battery in the same orientation as the old one, ensuring the “+” side is correctly positioned. Press it firmly into place.
Step 6: Reassemble the Key Fob
Carefully place the inner component back into the key fob casing. Align the two halves of the fob and press them together. Replace the small Phillips head screw and tighten it gently but securely. Finally, reinsert the emergency key.
By following these simple steps, you can easily change the battery in your Dodge key fob and ensure you remain in control of your vehicle’s remote functions. Regularly checking your key fob battery can prevent unexpected lockouts and keep you on the road without interruption.
