Changing the battery
Key with remote in the head
- The remote electronics sit in the plastic head of the key itself, so there is no separate fob to open.
- 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.
If a child might have swallowed a coin cell, treat it as an emergency and get to a hospital right away.
