If you have a Hyundai car, it’s important to change the car key battery. This is because if the key battery is not working, your car will not start. You can do this by going to a mechanic or by yourself. To change the car key battery in a Hyundai, you will need: -A Phillips head screwdriver -A flathead screwdriver -A hammer -A wrench (optional) -1/2 cup of water (optional)

  1. Remove the old key battery from your Hyundai. If you don’t have one, get one here: https://www.amazon.com/gp/product/B00KL4QK8M/ref=oh_aui_detailpage_o01?ie=UTF8&psc=1&qid=14N3VcwzCv&sr=8-1&keywords=car+key+battery%EF%BC%B4
  2. Place the new key battery in place on top of the old one. Make sure that both batteries are facing outwards so that they are touching each other evenly. If they’re not facing outwards, make sure that you turn them so that they are!
  3. Use your Phillips head screwdriver to screw the two batteries together until they’re tight against each other (you may need to use a hammer if they’re not tight). Make sure that there’s no space between them!
  4. Use your flathead screwdriver to screw the screws into place until they’re fully screwed in (you may need to use a hammer if they’re not fully screwed in). Make sure that there’s no space between them!
  5. Put your hand over top of both batteries and hold them together with your fingers while using your other hand to twist them around so that their tips meet in the middle (you may need to use a wrench if they don’t meet).
