Alright. So in this video, I'm going to show you how to change the key Fob battery and a Ford Fiesta. And this started being used in 2015 to present so for some of the newer Fiesta models, actually has a smart remote. It looks like this. So to get to the battery here, we're going to separate this piece.

You can see there's kind of a line that goes all the way around the key Fob. Here we go. Separate this into two pieces. And the key to this is in the upper right. If you look at the keywords, like where my right index finger is, right here, there's a little bit of a notch.

So we turn it this way. You can see there's a small notch. You can get a little bit of leverage. We got to pry these two pieces apart. So easiest way I found is you can take a flathead screwdriver.

You can actually just take another key, kind of stick it in there and just turn it. Try to get some leverage and pry these two parts apart. And it will be a little difficult. But you're able to get into that notch and turn. You'll be able to separate these two pieces.

You can also go right here where the keyring might go, and pop these two pieces off. There's a little rubber backing that may come off or stay just covers the battery. Here the battery that need change the CR 2032. Tap that out and that will fall right out. And when you're putting in a new coin battery, just make sure again, CR 2032, make sure the positive side is facing towards you.

Positive side has the lettering on it, like, so pop that back in and then just go ahead and replace the backing. And this will all kind of snap back together really nice and easy. So that's how you change the battery on Fiesta key Fob. And again, this is a CR 2032 battery. I'll put a link to the bottom.
