Changing the battery

Smart key (push-button start)

  1. Find the small release on the edge or back of the fob and hold it while you pull out the metal emergency key.
  2. Look inside the empty key slot for a notch. Put the tip of the metal key or a small flat screwdriver wrapped in tape there and twist gently until the shell splits.
  3. Note which side of the old coin cell faces up (usually the side with the writing), lift it out with a plastic tool, and press the new one in the same way.
  4. Reassemble, refit the emergency key, and check that the car sees the fob when you press start.

Kia smart keys usually free the mechanical key with a button, and the case opens at the gap it leaves.

A CR2032 is 20 mm across and 3.2 mm thick. CR2032, CR2025 and CR2016 share the same width but not the same thickness, so a swap between them can leave a loose contact or a case that will not close.

A CR2450 is 24.5 mm across and 5.0 mm thick, much fatter than a CR2032. A thinner cell will rattle and lose contact, so buy the exact size.

Flip key

  1. Open the flip blade. Never force the hinge sideways, since the spring and pin are the weak part of a flip key.
  2. Look along the edge for a notch. A coin turned in that notch usually separates the remote half from the blade half.
  3. Take out the old cell, noting which side faced you, and fit the new one the same way.
  4. Press the halves together until no gap shows, then try every button.

A CR2032 is 20 mm across and 3.2 mm thick. CR2032, CR2025 and CR2016 share the same width but not the same thickness, so a swap between them can leave a loose contact or a case that will not close.

Coin cells are a choking and burn hazard for children. Store the spares in their original pack, out of reach.
