Smart keys are everywhere, and it’s really important to have a good quality key battery in the car key. This is because if the car doesn’t detect the key battery, the car will not start. This is such a stupid idea, because one day, the key battery is going to go flat. However, it’s what we’re stuck with, so here’s our guide to changing the key battery on a Hyundai Santa Fe Keyless Car.
As usual, we’ve broken it down into easy stes and there is a YouTube video at the end to help if needed.
Step 1 HOW TO Change Key Battery on Hyundai Santa Fe Keyless Car Remote
So this week, we’ve got a 2015 Santa Fe key. It’s a proximity key with three buttons, and we’re going to show you how to change the key battery. The first thing is, you need to press the little silver button, that let’s you take the emergency key blade out. Put that to one side. So the way that the key opens, is that there is a line all the way around the key. It splits in two halves.
So the top part comes away from the bottom half. So you need a screwdriver to separate the two halves.

Now, you can see someone before has had a small screwdriver in there, and it damages the groove. It moves around too much in the slot and chews it up. So, I would say, get a nice big screwdriver, one that fills up that gap.
Put it into the gap, and just give it a twist.
You’ll hear a ‘crack’, and that is the key opening up. Then, what you need to do, is just gently put a small screwdriver where you see an opening and give it a gentle twist. That just helps the key open. And there you go.
So that’s the key open. Now, just a little warning on this here.
These are the really delicate components. So if you’re rough with the screwdriver, when you open it, and you damage these components, the car won’t start. So, it’s really important, so as you open it, just to go careful.

So, we’ve got the key apart, and the battery is a CR2032. Click on the Amzon link below to buy these.
So, we’re going change that. Okay. So there’s a plus sign there, and you’ve got the writing, and the plus sign there. So just turn it over, so that you can’t see the writing. So, we’re going put the key back together. And, when you do that, it’s a bit of a snap. It’s quite tight, so you think you’re doing something wrong, but you’re not. And, the last thing, is just to put the blade away. And then, so with a three button Santa Fe key, you’re good to go.
