Changing the battery
Key with remote in the head
- The remote electronics sit in the plastic head of the key itself, so there is no separate fob to open.
- Find the seam around the head. Twist a coin or small flat screwdriver in the notch at the blade end or side until the halves part.
- The coin cell is usually under or on the back of a small board. Keep the rubber button pad in place while you swap the cell.
- Snap it closed and press each button. The car still starts with a dead remote battery on most of these keys, because the start chip needs no battery.
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.
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.
- 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.
- Reassemble, refit the emergency key, and check that the car sees the fob when you press start.

Remote key (form not stated in the source)
- Key shape is not stated by the source. Compare your key with the types described on the how-it-works page.
- Look for a notch, slide or screw on the case. A coin or small flat screwdriver, twisted gently, opens most fobs.
- Replace the cell with the same side up, close the case, and test.

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.
