I’ve got a 2017 i10, UK spec model. Do you know how to swap out the key fob battery (I think it’s a CR2032)? And is there anything else I need to do once I’ve put in the new battery, like pre-programming it?

To change the battery, just flip the key fob over and you’ll notice it’s split into two sections. Use something like a butter knife to gently pry open the larger section, and you’ll find the battery inside. Swap it out with a new one, make sure it’s a good quality battery. Then just snap the case back together – easy peasy! And no need to reprogram anything.

Check if it’s the same key fob, using a butter knife might make it simpler.

Hey, I’ve got the same key fob for my 2021 i20, and I just tried removing the part that covers the battery. You can actually do it by hand, like they show in the video from 0.54 minutes onwards. Just a heads up though, when I took off the cover, the battery kind of popped out, so it might be a good idea to do this indoors in a carpeted room!

To replace the battery, you just push it towards the Hyundai “H” logo on the fob and then slide it in the opposite direction to lock it in place.

To swap the CR2032 battery in a 2017 i10 key fob:

  1. open the fob
  2. replace the battery
  3. close it.

No pre-programming is needed; the fob should work immediately after the battery change.

If the problem persist please call your mechanic or take it back to Hyundai dealer @Dolph

  5. It’s best to avoid touching the new battery too much to maintain its cleanliness.

Replacing the battery in your 2017 Hyundai i10 key fob is a breeze and doesn’t require any pre-programming.

Here’s a quick rundown:

1.Pop open the key fob: There’s usually a small notch on the side or bottom. Use a flat-head screwdriver (carefully!) to pry it open at the notch.
2. Identify the battery: It should be a small, round battery. Most likely, it is a CR2032, but double-check to be sure (the model will be printed on the battery itself).
3. Swap the battery: Take note of how the positive (+) and negative (-) sides are oriented. Pop in the new battery with the same orientation.
4. Snap it shut: Press the fob halves back together firmly until they click closed.

Did you already have a new CR2032 battery on hand, or do you need to pick one up at the store?

pre-programming isnt required.

  1. Find the seam on your key fob, maybe a small notch. Gently use a flat screwdriver to open it there.
  2. Inside, there’s a small round battery (likely CR2032, but check the writing on it).
  3. Put the new battery in exactly how the old one was (positive (+) and negative (-) sides match).
  4. Push the fob halves back together firmly until it clicks shut.
