The battery used in the ignition key for Jeep cars is the CR2450 3 Volt. Using a small flat-head screwdriver, open the key housing by prying at its centre. Perform this operation carefully, detaching each small part of the housing a little at a time.

Voila! The bulk of the work is already done! Now you have the sought-after battery in front of you. Again, use the screwdriver to pry under the battery itself and remove it. Insert the new battery you purchased and close the housing simply by pressing the two parts of the key together until they click into place.

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.
