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. Use the slot where the metal key sat. Twist, do not lever hard, and work along the seam until the halves separate.
  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. Close the case until it clicks all the way round, put the metal key back, then try the buttons and a push-button start.

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.

Remote key (form not stated in the source)

  1. Key shape is not stated by the source. Compare your key with the types described on the how-it-works page.
  2. Look for a notch, slide or screw on the case. A coin or small flat screwdriver, twisted gently, opens most fobs.
  3. Fit the new cell matching the old one's orientation and test the buttons.

If a child might have swallowed a coin cell, treat it as an emergency and get to a hospital right away.
