Changing the battery
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.
- Replace the cell with the same face showing, and make sure the rubber keypad sits flat before closing.
- 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.
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.
