Old Prius (2004-2009) Key Fob Battery Replacement CR 2023

Wish I were the genius that put this together - the key fob I mean, not the video (which is excellent BTW).

Sure, it built on incremental enhancements over years, I'm sure.

1. Take out the emergency physical key - for which you pull on the spring loaded latch you see on the side where the emergency key sticks out.
2. With the latch in that position (pressure still applied with your fingernail), you can press and push up on the back cover (that is, the opposite side of the fob from the buttons). This should cause the back cover to slide up and you can remove it.
3. Now, you see four screws that you need to remove with a tiny Philips head screw driver
4. That done, you see a rubber arc that overlaps the battery and helps keep it in place. If you push down on the battery near that rubber arc, it will pop out slightly on the opposite edge. That will help remove it.

And that's it. I'd love to see how this has been improved in the newer versions.
