Changing the battery

Key with remote in the head

  1. The remote electronics sit in the plastic head of the key itself, so there is no separate fob to open.
  2. Find the seam around the head. Twist a coin or small flat screwdriver in the notch at the blade end or side until the halves part.
  3. Replace the cell with the same face showing, and make sure the rubber keypad sits flat before closing.
  4. 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.

If a child might have swallowed a coin cell, treat it as an emergency and get to a hospital right away.
