A dead key fob battery can leave you stranded, so knowing how to change it yourself is essential. This guide provides a clear, step-by-step process to get your key fob working again in minutes.

Identifying Your 2012 Toyota Prius Key Fob

Before you begin, ensure you have the correct key fob. The 2012 Prius typically uses a standard flip key or a smart key fob. This guide covers both types. Recognizing the specific type of key fob you have is the first step to a successful battery replacement.

Gathering the Necessary Tools

You’ll need only a few tools for this task: a small flat-head screwdriver or a similar prying tool, and of course, a new CR2032 battery. These are readily available at most stores. Having the correct tools will make the process smooth and efficient.

Step-by-Step Guide for the Flip Key

1. Locate the release button: On the side of your key fob, you’ll find a small release button. Press this button to separate the mechanical key from the fob.
2. Open the fob: Use the flat-head screwdriver to carefully pry open the key fob casing. Start by inserting the screwdriver into the small groove where the mechanical key was attached. Gently twist to separate the two halves of the fob.
3. Remove the old battery: Once the fob is open, you should see the CR2032 battery. Carefully pry it out using your flat-head screwdriver. Avoid damaging the contacts inside the fob.
4. Insert the new battery: Place the new CR2032 battery into the compartment, ensuring the positive (+) side faces up. Press gently until it clicks into place.
5. Reassemble the fob: Align the two halves of the key fob and press them together firmly until they snap shut.
6. Reattach the mechanical key: Slide the mechanical key back into its slot until it clicks.

Step-by-Step Guide for the Smart Key Fob

The process for changing the battery in a smart key is similar, with a few slight variations.

1. Locate the notch: On the side of your smart key, there’s a small notch. Insert your flat-head screwdriver into this notch.
2. Separate the key fob halves: Gently twist the screwdriver to separate the two halves of the key fob. Be careful not to apply excessive force.
3. Replace the battery: Locate the CR2032 battery and carefully pry it out. Insert the new battery, positive (+) side up, and press it into place.
4. Reassemble the fob: Carefully align the two halves of the key fob and press them together firmly until they click back into place.

Testing the Key Fob

After replacing the battery, test all the key fob functions, including locking and unlocking the doors and starting the car. If the key fob isn’t working, double-check that the battery is correctly installed and that the contacts are clean.

Troubleshooting

Sometimes, even after replacing the battery, your key fob might not work. This could be due to a variety of reasons, including damaged contacts or a faulty key fob. If this happens, consult your owner’s manual or a qualified automotive technician.
