Changing the battery

Flip key

  1. Open the flip blade. Never force the hinge sideways, since the spring and pin are the weak part of a flip key.
  2. Look along the edge for a notch. A coin turned in that notch usually separates the remote half from the blade half.
  3. Take out the old cell, noting which side faced you, and fit the new one the same way.
  4. Press the halves together until no gap shows, then try every button.

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)

  1. Find the small release on the edge or back of the fob and hold it while you pull out the metal emergency key.
  2. The gap left by the metal key usually has a pry point. A slow twist with a thin flat tool (tape on the tip saves the plastic) opens the two halves.
  3. 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.
  4. Snap the halves back together, slide the metal key home, and press each button, then try the start button from the driver's seat.

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.

Coin cells are a choking and burn hazard for children. Store the spares in their original pack, out of reach.
