Signs Your Toyota Prius V Key Fob Battery Needs Replacing

Before we dive into the replacement process, let’s first look at some common signs indicating your key fob battery is nearing its end:

What You’ll Need to Replace the Battery

Replacing the battery in your Toyota Prius V key fob is a relatively simple task, and you only need a few items:

New CR2032 Battery: This is the standard battery type for most Toyota Prius V key fobs.

Follow these steps to replace the battery in your Toyota Prius V key fob:

Locate the Key Fob Release Button: On the back of your key fob, find the small release button.
Release the Metal Key: Press the release button and gently slide out the metal key from the fob.
Separate the Key Fob Halves: Use a small flat-head screwdriver or a plastic prying tool to carefully separate the two halves of the key fob casing. Start at the notch where the metal key was released, and gently pry open the casing.
Remove the Old Battery: Once the casing is open, you’ll see the old CR2032 battery. Gently pry it out, noting the orientation of the positive (+) side.
Install the New Battery: Insert the new CR2032 battery into the fob, ensuring the positive (+) side faces the same direction as the old battery.
Reassemble the Key Fob: Carefully align the two halves of the key fob casing and press them together firmly until you hear a click, indicating the casing is securely closed.
Reinsert the Metal Key: Slide the metal key back into its slot on the key fob until it locks in place.
Test the Key Fob: Test all the buttons on your key fob (lock, unlock, panic, etc.) to ensure the new battery is working properly.

Still Having Trouble?

Key Fob Programming: In some cases, you may need to reprogram your key fob after replacing the battery.
Faulty Key Fob: The key fob itself could be damaged or malfunctioning.
