Changing the battery

Separate remote fob

  1. This remote is its own fob, separate from the metal key, which makes it one of the easier ones to open.
  2. Look for a screw on the back or a notch on the edge. Remove the screw if present, then twist a coin in the notch to split the case.
  3. Swap the cell or cells, keeping the same side up as the old ones.
  4. Reassemble and test from a short distance.

This key takes two CR2016 cells. Change both at the same time and stack them the way the old pair sat; mixing a fresh cell with a tired one shortens the life of the new one.

Key with remote in the head

  1. Here the key blade and remote are one piece. You open the plastic head, not the blade.
  2. Many key heads split along the side seam. Start at the small notch and pry a little at a time.
  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.
