Changing the battery
Smart key (push-button start)
- Find the small release on the edge or back of the fob and hold it while you pull out the metal emergency key.
- Use the slot where the metal key sat. Twist, do not lever hard, and work along the seam until the halves separate.
- Before you take the old cell out, look at its face. Put the new cell in with the same side showing, and avoid touching both faces at once.
- Snap the halves back together, slide the metal key home, and press each button, then try the start button from the driver's seat.
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.
Keep spare coin cells away from small children. A swallowed coin cell can burn the throat within hours; if it happens, go to an emergency room at once.
