Changing the battery

Key with remote in the head

  1. Here the key blade and remote are one piece. You open the plastic head, not the blade.
  2. Work a thin flat tool into the seam near the blade and twist; go round slowly if it does not open at once.
  3. Replace the cell with the same face showing, and make sure the rubber keypad sits flat before closing.
  4. Close the head, check there is no gap, and try the buttons.

A CR1620 is 16 mm across and 2.0 mm thick. It is easy to confuse with the 20 mm CR20xx sizes, which will not fit.

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. 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.
  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.

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