Changing the battery
Key with remote in the head
- This type has the buttons built into the key head. The cell is inside that head, between two clipped halves.
- Many key heads split along the side seam. Start at the small notch and pry a little at a time.
- Inside you may find a small circuit board in a tray. Lift the board out if the cell is underneath, swap the cell with the same side up, and refit the board.
- Press the head together until it clicks and test the buttons. The transponder chip that lets the car start is separate from the battery, so starting should not change.
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.
Smart key (push-button start)
- Start by freeing the hidden metal key: there is a latch or slide on the case, and the blade comes out once it moves.
- Use the slot where the metal key sat. Twist, do not lever hard, and work along the seam until the halves separate.
- Pop the old battery out with a toothpick or plastic pick, not a metal blade, and seat the new one with the + side matching the old one.
- Snap the halves back together, slide the metal key home, and press each button, then try the start button from the driver's seat.

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.
