Changing the battery

Key with remote in the head

  1. The remote electronics sit in the plastic head of the key itself, so there is no separate fob to open.
  2. Many key heads split along the side seam. Start at the small notch and pry a little at a time.
  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. 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.

Flip key

  1. Swing the key blade open first. On most flip keys the cell lives in the body behind the hinge.
  2. Look along the edge for a notch. A coin turned in that notch usually separates the remote half from the blade half.
  3. Lift the cell out with a plastic tool and press in the new one with the + side matching.
  4. Press the halves together until no gap shows, then try every button.

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.
