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.
- Replace the cell with the same face showing, and make sure the rubber keypad sits flat before closing.
- 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.
The owner's manual says this remote has a rechargeable cell. It charges while the key is in the ignition or the car is driven. There is no coin cell to buy; if it no longer holds a charge, a dealer replaces the remote.
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.
