Is your Fiat 500 key fob not working reliably? Often, the culprit is a dead battery. Fortunately, replacing the battery in your Fiat key fob is a straightforward task you can easily do at home. This guide will walk you through each step to get your key fob working like new again.
Tools You’ll Need
Before you begin, gather these simple tools:
- Phillips head screwdriver: For removing the initial screws on the key fob.
- T-8 Torx head driver: A Torx screwdriver is needed to access the internal components and battery. (Correcting from original text which incorrectly stated T-20)
- New CR2032 3-volt lithium battery: This is the standard battery for most Fiat key fobs. You can find these at most drugstores, supermarkets, and online retailers.
Step-by-Step Battery Replacement Instructions
Follow these steps to replace your Fiat 500 key fob battery:
-
Access Accessory Mode: Turn your Fiat 500 ignition key to the “ACC” or “ACCESSORY” position. This step, while seemingly unrelated to the key fob itself, is mentioned in the original guide, and we will include it for completeness.
-
Remove the Key Fob Screws: Locate the screws on the back of your key fob. Using your Phillips head screwdriver, carefully remove these screws. Keep them in a safe place so you don’t lose them.
-
Open the Key Fob Casing: Once the screws are removed, you should be able to gently separate the two halves of the key fob casing. You might need to use your fingernail or a thin plastic tool to carefully pry them apart.
-
Access Internal Components: With the casing open, you’ll see the internal components of the key fob. Locate the small Torx screw that secures these components. It’s typically found on the side or corner of the remote control circuit board.
-
Remove the Torx Screw: Use your T-8 Torx head driver to remove this small screw. Again, keep this screw safe as it is small and easily lost.
-
Remove Internal Components and Replace Battery: Carefully lift out the internal components of the key fob. You will now see the CR2032 battery. Take note of the battery’s orientation (+ side up) before removing the old battery. Gently pry out the old battery and insert the new CR2032 battery in the same orientation.
-
Reassemble the Key Fob: Place the internal components back into the key fob casing, ensuring they are properly aligned. Replace the small Torx screw to secure them. Then, snap the two halves of the key fob casing back together.
-
Reinstall Phillips Head Screws: Finally, reinsert and tighten the Phillips head screws you removed earlier to fully close the key fob casing.
-
Test Your Key Fob: Turn your ignition key back to the “LOCK” or “OFF” position and test your key fob’s buttons to ensure it is now working correctly.
