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. 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.
  3. 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.
  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. Start by freeing the hidden metal key: there is a latch or slide on the case, and the blade comes out once it moves.
  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.

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.
