Key with remote in the head
- Here the key blade and remote are one piece. You open the plastic head, not the blade.
- Many key heads split along the side seam. Start at the small notch and pry a little at a time.
- 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.
- 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.
