The best “how to” video I have ever seen on You Tube. Nice and clear, useful background information, informative tips and the best bit...no annoying padding that you can get in some of this sort of video. Everything in this one is useful and beautifully presented. And my key remote works again. Thank you!

Such a great video. Presenter helpful, clear, great tips, first class. Thank you ! You’ve just helped me out big time.

Thanks for making this. Alot easier than I thought. Now just need to find a spare key and a new key shell. Hyundai in Australia charges $800 for the FOB, so many order from UK again

Thank you so much!! Yesterday my car voiced that my car key had low battery. And it turned out the spare key was completely out so i kind of panicked cause I've heard that it's really pricey to change the key. But i googled and found your video and it turns out it's really simple! So thank you so much for the help! 🤗😁 Have an awesome weekend 😊

Thanks a lot
Works the same for the 3 button keys with the same shape BTW.
Saves me a trip to the garage (even though it's free since it's a company car).
