Let's see how to replace the battery of the key/remote of a 2020 Toyota Corolla. Let's get a button battery of the CR2032 type right away, which we can find at any supermarket or electronics store, or online like the youtuber did. We will also need a small flathead screwdriver.

On the top of the remote (where the key ring is) we will find a lever that we will slide to the right: lift the key ring and remove the physical key, pry between the two halves of the remote to open it and inside we will find the button battery. Change it, paying attention to the polarity, then close the cover and put the physical key back in place.

Operation completed.

How to reset the tyre pressure warning light on the Kia Niro EV?

To reset the tyre pressure warning light on the Kia Niro EV, inflate the tyres until they reach the correct pressure value. This value is indicated on the sticker attached to the driver's door pillar. Once the tyres are inflated, turn on the instrument cluster to check that the warning light has completely disappeared from the display. If it is still present, you may need to drive for a few miles to ensure it disappears completely from the screen.
