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. 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. Close the head, check there is no gap, and try the buttons.

A CR2016 is 20 mm across and 1.6 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.
