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. The gap left by the metal key usually has a pry point. A slow twist with a thin flat tool (tape on the tip saves the plastic) opens the two halves.
  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. Snap the halves back together, slide the metal key home, and press each button, then try the start button from the driver's seat.

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.

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