Step By Step Process On: How To Change A Toyota Car Key Battery?

Here I will explain you step by step process of how to change a toyota car key battery? let’s see how to change a toyota car key battery.

Step-01:

If you have a key like this – the same shape as this – and it’s got three or four buttons on it and it looks just like this, then this will work. So, what you want to do first is look all around the perimeter of the key and you’ll notice that in the one top corner here there’s a little slot for a screwdriver right near the keyring. And by the way, you don’t have to take this keyring off to do this job.

Step-02:

So, what you want to do is get yourself a butter knife – something that’s not going to cut yourself – but so just stick it in there and give it a twist and the two pieces will come apart just like that. And, what you want to do is, if you look on here, it says “Use coin to open.” There’s a little arrow pointing into the corner, so what our knife is, is kind of like a coin. So, we’re going to use that to – we’ll just go gentle – so we’ll just pry it out of there and there we go. That piece comes right out.

Step-03:

So now, if you look at this and you look around the outside, you’ll see that there’s one, two, three, four, five, six, and all those little fingers need to be lifted up. In this little black cover will come off. So, what you want to do is you want to go around and just pry each one of these little fingers up a bit and maybe use your nail in there to hold it up a bit as it undoes. Just like that, go to the next one and then go over the next ones along the side here. And you can see it’s slowly coming off. There we go. And then just pull it right off.

Step-04:

And you’ll see inside there’s a CR2016 battery. Use the screwdriver in one of these little spots here and pop it out. And so, once you get your battery, just make sure it’s the – the printing on the battery is pointing upwards – and slip it back in there. And then just take your your black cover and it will only fit on one way. So just look at the shape.

Step-05:

Now, as far as the key fob goes, these are pretty slippery guys when you take the batteries out of them. As you’re you’re fumbling with it, it will fire out of your hands and everything. A little flying. Well, these little buttons in here, they will come out. So, they just go – they just fit back in. They only go in one place. So, you just have to play with them a bit and get them to drop back in there.

Step-06:

And so, once you’ve done that, just take your your fob and flip it around and look at the shape again. See, it’s got this little piece there and you’ve got a shape right there that’s the same. So, just put her back in there. Push your down in. Take the cover and that’s it. And you’re ready to go.
