How do you change the battery?
It's super easy! All you need to do is open up the key fob and replace the coin cell battery.
What you'll need:
- Your Prius key fob
- Small flathead screwdriver / butter knife / file
- Replacement battery: CR1632.
- On Amazon, I bought two for $6.72. I was unable to find these batteries at my local Safeway or CVS.

To crack open the fob, insert the metal key into the notch

Remove the circuit board from the plastic casing.
You can just use your fingernail to pull it out. There is
some tape in the back of the circuit board so there may be some resistance.

Remove the battery from the back of the circuit board, using
a small screwdriver or a file. The battery is kept in place by 3 little tabs
so you don’t need that much force.
Pay attention to the battery orientation so you can copy it when you insert the new battery. In my case, the + side is up. For certainty, there are instructions
embossed in the casing.
