Step-by-Step Guide to Battery Replacement
Follow these detailed instructions to replace your 2012 Fiat 500 Key Fob Battery:
Step 1: Accessing the Key Fob
To begin, you’ll need to separate the key fob from the ignition key. Locate the small release button or slider on your Fiat 500 key. Press and hold this button while gently pulling the key fob portion away from the metal key blade. This will give you access to the key fob casing and screws.
Step 2: Opening the Key Fob Casing
Once you have the key fob separated, turn it over to locate the screws on the back. Using your Phillips head screwdriver, carefully remove the two screws securing the back cover of the key fob. Place these screws in a safe place where you won’t lose them. After removing the screws, gently pry open the back cover of the key fob. You might need to use your fingernail or a thin plastic tool to help separate the two halves of the casing.
Step 3: Removing the Old Battery
With the key fob casing open, you’ll see the internal components and the battery. Identify the small Torx screw that secures the internal components. Using your T-8 Torx head driver, carefully remove this screw. Once the screw is removed, you can gently lift out the internal module from the key fob casing. The CR2032 battery will be visible within this module. Take note of the battery’s orientation (+ side up or down) before removing it. You can typically pry the old battery out using your fingernail or a small non-metallic tool.
Step 4: Installing the New Battery
Now, take your new CR2032 battery and install it in the same orientation as the old battery you just removed. Ensure it is securely placed in the battery compartment.
Step 5: Reassembling the Key Fob
Carefully place the internal module back into the key fob casing, making sure it aligns correctly. Reinstall the T-8 Torx screw to secure the module. Next, align the back cover of the key fob and snap it back into place. Finally, reinsert and tighten the two Phillips head screws to fully secure the casing. Reattach the key fob to the ignition key blade until it clicks into place.
Your 2012 Fiat 500 key fob battery replacement is now complete! Test the key fob to ensure the keyless entry system is working correctly. If you follow these steps, replacing your Fiat 500 key fob battery should be a quick and easy process, saving you time and money compared to a dealership visit for a simple battery change.
