Let's see how to change the battery in a smart key for the Hyundai Tucson. Press the small side button located near the base of the key and pull out the emergency metal blade.

Insert a flat screwdriver into the gap created after removing the blade and lever it to open the plastic shell. Separate the two halves with a click.

Remove the old battery, being careful of the polarity; usually, the positive terminal faces upwards. The battery you need is a common CR2032, which can be easily obtained from a newsagent or an electronics or hardware store.

Insert the new battery in the same position, snap the two halves back together until they click, and reinsert the metal blade.

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.
