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.
- Work a thin flat tool into the seam near the blade and twist; go round slowly if it does not open at once.
- 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.
Coin cells are a choking and burn hazard for children. Store the spares in their original pack, out of reach.
